FAQ > Car, Truck and SUV Rear View Mirrors
My   car   has   a   rear   view   mirror   that   looks   very   complicated,   Is   it   going   to   be   an   issue   when   I   have   Phoenix   Glass replaces my windshield? Rear   view   mirrors   in   today   vehicles   do   appear   to   be   something   to   be   afraid   of   and   some   are   but   in   reality,   the   majority   of   them   are   just business   as   usual   for   the   technicians   at   Phoenix   Glass.   There   are   a   few   out   there   that   can   be   rather   difficult   to   transfer   over   to   the   new windshield   such   as   Infinity,   Lexus,   BMW   and   a   few   other   makes.      Unfortunately   for   that   simple   reason   it   puts   some   vehicles   into   the difficult   installations   category   in   which   we   would   rather   not   perform   the   installation   in   the   field.      These   types   of   rear   view   mirrors   use   a horse   shoe   shaped   spring   that   maintains   an   equal   pressure   on   each   of   the   two   ball bearings   to   retain   the   mirror   to   the   mounting   bracket.      It's   not   at   all   uncommon   for   a technician   to   have   difficulty   with   these   type   of   units   in   that   it   will   pop   apart   and   the small   BB   sized   ball   bearings   exit   the   mirror   in   an   unsafe,   unruly,   flying   formation.     Imagine   trying   to   find   something   smaller   than   a   BB   in   a   parking   lot   or   worse   yet   a gravel parking lot.
99% of the new windshields of today come from the factory with the rear view mirror mounting bracket already mounted on the windshield.
My Rear View Mirror fell off my windshield, Can Phoenix Glass reattach it for me? No   problem,   and   we   can   usually   do   it   while   you   wait   and   you   will   also   receive   a   life   time   warranty   for   the   work.      In   the   unlikely   event   of it falling off again we'll put it back on for free for as long as you own the vehicle.

An Interpretation of the Standard: Passenger   vehicles   must   have   an   inside   mirror   along   with   a   driver’s   side mirror for rear viewin g.
Federal   Motor   Vehicle   Safety   Standard   111   is   a   specification   pertaining   to   the   rear   vision   parts   of   a   vehicle.   This federal   standard   outlines   important   safety   requirements   as   it   relates   to   automotive   mirrors.   FMVSS   111 specifies   the   required   range   of   vision   that   the   driver   must   achieve   utilizing   rear   vision   products.   These   ranges are   both   horizontal   and   vertical   angles   from   the   side   and   rear   of   the   vehicle.   In   addition,   FMVSS   111   states that   rear   vision   products   shall   have   an   average   reflectance   of   at   least   35   percent   (OEM   mirrors   are   typically between   40%   and   60%   reflective).      This   part   of   the   specification   is   achieved   through   the   use   of   special   first surface chrome glass.
Federal Motor Vehicle Safety Standard  (FMVSS-111)
The   key   function   for   rearview   mirrors   is   to   maximize   the   field   of   vision   of   the   area   behind   the   driver.   The   convex   mirror   was   designed   to increase   that   field   of   view.   The   federal   law   does   not   specifically   dictate   usage   of   convex   mirror   for   passenger   side   viewing;   however,   to be   on   the   safe   side,   if   a   convex   mirror   part   was   originally   used   then   convex   mirror   should   be   reinstalled   to   maintain   the   maximum   field of vision.
The   passenger   side   mirror   is   optional   as   long   as   there   is   a   field   of   vision   from   using   an   inside   rearview   mirror.     It   can   be   flat   or   convex   and   if   it   is   a   convex   mirror,   the   insignia   “Objects   are   closer   than   they   appear”   must   be inscribed on the mirror.
If   viewing   from   an   inside   mirror   is   impossible,   an   example   of   this   would   be   one   of   our   Phoenix   Glass   Mobile Installation vans, the vehicle must have a passenger side mirror along with a driver’s side mirror .
If   there   was   a   convex   part   on   the   vehicle   originally,   it   should   be   replaced   with   a   convex   part   etched   with   the   proper   “OBJECTS   IN MIRROR ARE CLOSER THAN THEY APPEAR” statement.
This vehicle must have a passenger side mirror along with a driver’s side mirror. FMVSS-111 Rear vision requirments for cars and trucks An example of a car or truck, interior rear view mirror with manual day night operation. Drivers side view mirror The passenger side mirror is optional as long as there is a field of vision from using an inside rearview mirror.  It can be flat or convex and if it is a convex mirror, the insignia “Objects are closer than they appear” must be inscribed on the mirror.
My Car doesn’t have a side view mirror on the passenger’s side,  isn’t it supposed to?
What are the requirements for Rear and Side view Mirrors in Vehicles?
The passenger side mirror is optional as long as there is a field of vision from using an inside rearview mirror.
Requirements very depending on what type of vehicle you have, below you’ll find the Federal Motor Vehicle Safety Standard that applies to just about all Vehicles.
One   of   my   side   view   mirrors   on   my   car   has   a   crack   in   it.      Can   I   just   have   the   glass   replaced   or   do   I   have   to   buy   an entire unit?
An   Electrochromic   Mirror   is   a   mirror   that   electronically   automatically   dims   to   a   darker   color   when   it   is subjected   to   bright   light   such   as   headlights   from   the   vehicles   behind   you.      The   reason   we   ask   this question   is   the   vehicle   will   use   a   different   Windshield   if   it   has   one.      In   some   cases   the   vehicles   black matrix band may be different and in others it may be as simple as a different mirror mounting bracket.
In   most   cases,   depending   on   your   particular   vehicle   we   can   replace   just   the   glass   but   there   are   a   few   out   there   that   will   require   the entire mirror unit be replaced.  Stop by our Service Center and we will be able tell you what options are available to you.
The   second   type   is   an   Automatic   Dimming   Mirror.      It’s   the   more   modern   of   the   two   and   is   called an   Electrochromic   mirror.      Do   to   it’s   higher   cost   this   type   of   mirror   was   typically   only   found   in   today’s higher   end   vehicles   but   in   the   past   few   years   we   seen   them   in   a   variety   of   different   models.   It   works automatically   through   what   the   automotive   industry   refers   to   as   Electrochromism.      Sensors   which   are located   on   both   the   front   and   rear   of   the   mirror   detect   the   level   of   light   coming   from   the   front   as   well as   the   rear   of   the   the   vehicle.      The   Sensors   are   programmed   to   detect   night   driving   conditions   and focuses   on   areas   of   light   intensity   that   may   prove   to   be   a   problem   for   drivers.      When   the   sensors detect   light   they   send   an   electronic   signal   along   with   the   proper   voltage   level   to   the   mirror   activating the solution that is sandwiched between two layers of glass to darken.
When   I   called   Phoenix   Glass   to   obtain   a   price   on   a   new   Windshield   for   my   car   your CSR   asked   if   it   had   an   Electrochromic   Rear   View   Mirror.      What   is   an   Electrochromic Rear View Mirror?
An Electrochromic Rear View Mirror
In   an   effort   to   help   overcome      this   problem,   two   different   types   of   interior   dimming   mirrors   have been   created.      The   first   is   the   traditional   manually   operated   day/night   mirror.      This   is   the   one   you   are   most likely   to   be   familiar   with,   it   works   with   a   manually   operated   flip   tab   located   in   the   bottom   center   of   the   rear view   mirror.      You   flip   the   tab   and   it   adjusts   the   mirror’s   angle   to   a   light   dimming   reflection.      This   is   actually   the result   of   using   two   different   reflective   surfaces,   one   on   the   front   of   the   mirror   and   one   on   the   back.      The reflective   surface   on   the   back   is   lined   with   a   silver   derivative   material   that   makes   it   very   reflective,   while   the front   of   the   mirror   is   normal   glass   only   slightly   reflective.      This   entire   piece   of   glass   is   actually   a   wedge   shaped piece   of   glass   formed   to   a   particular   angle.      When   the   tab   on   the   mirror   is   set   in   the   Normal   position,   it’s positioned   so   the   backside   of   the   mirror   reflects   the   road,   but   when   flipped   up   into   it’s   night   time   mode   the normal   glass   in   front   handles   the   reflection,   returning   a   much   dimmer   version   of   the   road.      The   lesser   reflecting capabilities of the normal glass will help protect your eyes from bright light effects behind them.
A traditional manually operated day/night mirror.  This is the one you are most likely to be familiar with.
Most   people   think   the   interior   dimming   rear   view   mirror   is   just   another   gadget   the   auto   makers   came   up   with   as   a customer   convenience   but   they   were   actually    developed   as   a   result   of   the   many   accidents   that   are   caused   from   a visual   effect   known   as   The   Troxler   fading   effect.      The   Troxler   fading   affect   is    a   phenomenon   that   occurs   when   you try   to   focus   your   vision   on   a   single   point   in   space   for   more   than   20   seconds.      When   you   do   this   it   will   create   a stimulus   outside   the   range   of   your   focal   point   to   fade   away.      To   see   an   example   of   this   effect   click   on   the   photo   on your   right   and   then   try   focusing   on   the   red   dot   in   the   center   of   the   picture   for   10-15   seconds   and   you   will   see   that the   blue   circle   will   disappear.      T his   momentary   blindness   or   obscurity   can   cause   problems   for   drivers   d riving   at night   or   in   dark   conditions   because   The   Troxler   fading   effect   happens   automatically   when   your   eyes   are   exposed   to bright   lights,   be   it   from   your   rear   or   side   view   mirrors,   (typically   both)   on   coming   traffic   or   even   street   lights.      This happens   even   quicker   when   your   driving   in   rural   areas.   where   it’s   very   dark.      When   your   eyes   are   exposed   to   bright   lights   your   eyes immediately   compensate   by   tuning   out   distractions   so   you   can   focus   on   particular   things.      Unfortunately,   after   the   bright   light   disappears your   eyes   take   time   to   readjust   to   low   light   conditions,   especially   when   you're   trying   to   look   in   a   particular   direction.      The   continual distraction   of   bright   lights   from   behind   the   driver   can   be   even   worse   when   reflected   in   the   rear   view   mirrors   causing   the   eyes   to   slowly lose   sight   of   road   details   in   front   of   the   car.      To   reveal   the   effects   of   glare   on   the   eyes   that   drivers   must   endure   studies   that   have   been conducted   have   shown   that   The   Troxler   fading   effect   increases   driver   reaction   time   by   up   to   1.4   seconds.      This   means   that   when traveling   at   night   or   in   dark   conditions   at   60   mph,   it   would   take   you   1.4   seconds   which   translates   to   123   feet   more   than   normal   before you would be able to see again and be able to react to road hazards.
My   Cars   inside   rear   view   mirror   is   broken   and   I’ve   found   that   it   is   very   expensive   to   have   the   whole   unit   replaced.      I understand   I’ll   loose   the   dimming   capability   of   the   mirror   but   can   Phoenix   Glass   custom   cut   a   normal   type   of   mirror to fit it?.
That’s   a   simple   question   we’re   asked   almost   on   a   daily   basis   but   the   answer   isn’t   so   simple.      Let   us   start   out   with   Yes   we   Can   but   we’re sorry   to   say   we   Won’t.      Long   ago   it   was   done   with   both   rear   and   side   view   mirrors   on   a   regular   basis   and   considered   business   as   usual because   the   majority   of   people   didn’t   know   any   better   and   as   much   as   we   hate   to   say   it,   some   still   don’t.   The   mirror   glass   that   was   used is   the   same   type   of   1/8th   inch   thickness   mirror   glass   that   you   see   everyday   in   your   typical   bath   room   medicine   cabinet   mirror.      In   that type   of   situation   it   does   a   fantastic   job   but   in   an   automotive   application   it   can   literally   cost   you   your   life.         When   this   type   of   mirror   is used   in   an   automotive   application   the   reflection   it   gives   you   is   far   to   bright   in   dark   night   time   driving   conditions.      When   the   bright   light enters   your   eyes   it   causes   a   little   known   phenomenon   called   The   Troxler   Fading   Effect   that   can   literally   make   objects   disappear   before your very eyes.
What is the Troxler Fading Effect and how does it effect my night driving?
