All Lamp Assemblies
Chemical Damage to exterior polycarbonate headlamp and license lamp lenses. Note that most late modelvehicle headlamps and some license lamps have this type of lens. This material isused because of its temperature and high impact resistance.
A variety of chemicals can cause crazing or cracking of the polycarbonate lens. Headlampand other exterior lenses are very sensitive. Care should be exercised to avoid contactwith all exterior lenses when treating a vehicle with any type of chemical, such asthose recommended for rail dust removal. Also rubbing compound, grease/tar/oil removers,tire cleaners, prep solvents for pin stripping, cleaner/waxes, undiluted washer solvent,alcohol and even car wash soaps in too high a concentration may also damage the lens.The use of these products on the lens can result in the need to replace the entireheadlamp assembly.
The license lamp above exhibits a separation of the bond of the lens and housing,and a clouding of the polycarbonate lens. This condition was the result of applyingchrome cleaner to the rear bumper and license lamp.
This lamp shows some effects of chemical damage. Notice the milky color along theedge and the fracture. This was caused by a solvent used to prep the body for pinstriping.
Warning:Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exteriorlamps and lenses.
Overheating damage is most often presented as imperfections in the lens surface. Crazing or deformationsof the lens may occur if a shop mat or fender cover is draped over the fender andcovers a portion or all of the headlamp assembly while the DRL or headlamps are on.Covering the lamps restricts the amount of heat dissipated by the headlamps.
Warning:Care should be taken to not cover headlamps with shop mats or fender covers if thevehicle is being serviced while the headlamps or DRLs are illuminated. Covering anilluminated lamp can cause excessive heat buildup and crazing/deformation of the lensmay occur. The degradation of the lens can be unnoticeable at first and eventuallybecome hairline cracks in the lens. In extreme cases, it couldcause the lens to deform.
