Have really bad crazing on the inside of my headlights and can't seem to find a good replacement. Can these headlight cases be disassembled to recondition the inside lens, or does anyone know where I can get a quality replacement?

I've dismantled headlights before, but not Rlegendo ones.

Basically, you need a hot-air gun and some pries, or a lot of screwdrivers, or something. And plenty of patience.

Carefully go round it to soften the mastic and then gradually pry apart. Bearably painful on the fingers is about the correct temperature, so as not to distort things. Reassembly is largely the reverse, progressively squishing them back together.

Some people put the lamps in the oven, but that's scarily hit n' miss as they're often not very accurate at low temperatures.

The oven method mentioned by @Blues Legend can be found at . I would think that reassembly is critcal with respect to sealing the unit. In that regard perhaps a high quality clear and waterproof silicone caulk.

seems like a heat gun might give you more control...think I'll try to find a junkyard set to work with since it's a daily driver...all the google shows is the jdms, which look ugly to me...

You want consistent heat all around , heat gun wont get it hot enough, itll take MUCH longer. Also use butyl rubber, not silicone when you reinstall

Why your preference to butyl rubber as opposed to a good quality silicone?

thoiboi

because thats what was used when the headlight was first assembled and what most headlight retrofitters use to put it all back together.

Silicone also shrinks after time. Not as permanent as the rubber chewing gum.

John from PA

Not necessarily true for 100% silicone products. I used to work for GE and specifically use the Advanced Silicone 2 Window & Door Sealant for outdoor projects. The shrinkage is essentially “zero” as defined by ASTM testing codes. I do believe it would be more difficult to work with as opposed to the butyl rubber being suggested but would provide superior adhesion. Whether that capability is needed or not is a different matter. But one could say that since the original sealing method failed, perhaps something better is worth consideration.

Interesting to know. Probably less messy.

Lights are normally ventilated to prevent misting - it's just a matter of keeping the rain out at 90 MPH...

The crazing is likely due to sun damage - mine get cataracts on the outside only, as we aren't allowed intense sunlight.
