Are There Any Glass Replacement Headlights Available?


Recommended Posts

As you know, lens yellowing has always been a problem not only with Lexus, but almost all car makes. I have not heard of a source for glass lenses but they may be out there somewhere.

In the mean time, I did a search and found the following post on how to clean and polish your OEM lens in such a way as to remove the yellow and cloudy look. A much cheaper approach than replacing.

The lens has a silicone-based coating applied to its outer surface, some manufacturers apply two different types of coatings to the outer surface of the lens, these coatings are mainly for UVR protection, but are also for impact and abrasion resistance, once the coating (s) fail the lens surface will occlude (clouding or yellowing)

While most of the cloudiness is on the surface, severely discoloured lens cannot be brought back to optical clarity. If you live in a southern state, this discoloration can become noticeable in as little as two-years.

Application Methodology:

•Use a solvent type cleaner (Klasse or Zaino All-In-One) if this does not remove the oxidation use a plastic polish

•Meguiar’s PlastX contains a microscopic diminishing abrasive, which requires a little pressure when applying it to enable these abrasives to remove the discoloured plastic and expose new plastic. Or Renovo Plastic Cleaner

•Plastic Cleaners can be used to clean and condition Perspex as well as flexible plastic but is not suitable for use on glass.

•Prior to application of a plastic polish ensure that the window is clean and free from dust particles by washing with a soft cloth and warm water.

•It is not advisable to use cleaning detergents on plastic.

•Shake the bottle thoroughly. Plastic polish can be hand or machine applied

•Using a random orbital buffer with a 3.5-inch backing plate and a 4-inch (LC White) polishing pad or a terry cloth applicator

•Place a small dab (about ½-inch diameter) of plastic polish on the foam pad or applicator.

•Place the pad on the lens surface and turn on the machine (speed #4)

•Polish the lens repeatedly in a left-to-right and an up and down pattern.

•Continue polishing until all the polish is gone

•Wipe the lens with a damp Microfiber towel

•Inspect the lens, repeat the polishing process 2-3 times as necessary

•Plastic polish will not remove clarity defects that are within the plastic but it will remove external/surface scratching and oxidation (yellowing)

Wet-sanding- some OEM headlights have a coating applied this coating does not respond well to sanding test a small inconspicuous area. If the plastic starts to turn white, do not sand the lenses. Use a plastic polish (see Plastic Polishing)

When sanding the lens ensure that you sand in one direction only. It's important to keep the lines as straight and uniform as possible as they are often still slightly visible even after polishing. Providing the lines are in one direction you’ll never notice them once the acrylic coating is evenly applied. Otherwise random sanding lines will distort the light beam and become a distraction
