i have a pearl white +61404532026gt sl. overall the body is in near mint condition, with the exception of the headlight enclosures.

the entire panels, on both sides, for the headlamp has yellowed. as a result i have this beautiful white car with uglar tarrish yellowed headlamps. the area i’m referring to is the entire housing, not just right where the beam is, but the entire “eyes” of the car.

what i think i want to do is one of two things, depending on options:

a)if possible, remove the headlamps, clean off the yellowing and reinstall the headlamps.
b)if the yellowing can’t simply be cleaned, removed the headlamps and repaint them black and then reinstall them.

questions:
1. what are my options for fixing this problem?
2. are there any guides online for the removal of the headlamps? i have no clue how to take them out.

i started to type out procedure on how to take the lamps apart but then realized you have a 98. unless you’ve swapped out the lexan headlamps with glass ones (glass lamps only made in 94), it sounds like it’s just got a nasty film in them. you can’t really paint them because the paint is on the inside and i’ve heard it’s near impossible to wet sand off. i would try and find some lamps from a 94 made of glass.

this can be remedied easily with some tlc. buy sandpaper from 400 grit to 2000 grit or higher if you can find it and wet sand those puppies until the yellow is gone. then use a polishing compound to a glossy shine.

wetsanding wouldn’t fix this. the problem is the yellowing is beneath the glass/plastic cover of my headlamp. its in between the clear outer layer and the white inner-piece.

i really am hoping that i do not have to go out and buy brand new headlamps over this problem, but thats how it is sounding.

if it was an older model it sounds like it would be made of glass and i could just stick it in an over and take it apart. however, since its a 1998, if i am reading properly its plastic so thats not an option.

sigh, i hope someone comes up with some saving grace for me here….

i had the same problem on my 1996. my friend had it on his 1995. the way to fix it to simply buff it out with good buffing compound. my headlights looked brand new. better than ever. thats how you fix it.

ok, i did some more reading and i’m going to put my faith in the 3s community and assume that you’re all right and that i simply have to buff it out (but damn if it doesnt look like the yellow is beneath the plastic, not on top of it). i found a website where someone buffed it out and they said it took about 6 hours per headlamp. i wonder if there is any way to speed that up or if there are any tools i need.

additionally, i am wanting to change the color of this headlamp anyways. is there any company i can send the headlamps to to have their color changed or do i need to just contact my local body/paint shop?

questions:
1. is there any way to speed up buffing the headlamp (as opposed to 6 hours)?
2. what tools do i need (or would be recommended) to buff the headlamp (i.e. sand paper, if so what size, any power tools, etc.)
3. who should i contact about changing the color of the headlamp. i want the headlamp to be painted black.

sell your lights. buy used black lights off a 3kgt. 99’s won’t quite fit without a bit of jimmying the bumper.

or you can buy 94’s and robomod them. that’ll be black enough.

what is “robomod”?

so you don’t recommend i try and have someone paint my headlamps then? you think i would be able to find a good quality black headlamp that’s not faded?

do the 1994s fit my 1998? if so, which is recommended, the glass 94s or the lexan 98s?

95-98 3kgt lights are all identical…save for the color. painting them looks like crap, because the original paint was on the inside of the lens.

94’s were all glass.

94-96 stealth lights were square around the outside.

robomod can only currently be done with 94’s. search it.

i had the same problem with my 98 sl. wet sanded the areas where the light shines through, masked the area, and had the rest of the headlight painted, when the car got painted. the painted headlights look fine, a year later.

94s are hard to come by. i sold a set for $450 shipped a few months back. had quite a few people wanting them too.

i have restored two sets of 3s lights and a set of avenger headlights using the method from that site. i probly spent 2 hours each on the 3s headlights. they came out very well. the avenger headlights i might have spent 1 hour a piece on and the difference was remarkable. the car was my moms and she said the improvement on night vison alon was worth it, on top of it looking good again.
