Cornering Lamps Empty
PostSubject: Cornering Lamps   Cornering Lamps EmptyWed Dec 07, 2022 8:15 pm

Hello all. What are you guys doing about the yellow cornering lamps on your cars? My 99 is in excellent shape with the exception of the yellowed cornering lamps. Really bothers me.

I see GM still has the cornering lamps available for the 95-96, but the 97-99's are long discontinued. I wish someone made an aftermarket reproduction.

Can the 95-96's be adapted to fit the 99's? I'm wondering what's different on them? The housing, the lens, or both? I'm wondering if I could get new 95-96 lamps, then possibly dissect then lens and adapt to my current 99 cornering lamp housings?

It's hard to believe the cornering lenses changed after 96.  How much do new ones cost now?

I tried cleaning my old ones up, to no avail, and bought new ones.  I took the brand new lenses, sanded off the coating GM treated them with, and applied a better aftermarket coating.  That must have been a decade ago.  Can't remember the name of the stuff, but my lenses are still clear.  My Riv doesn't see much sunlight/UV though.

YouTube has a bunch of videos about taking the yellow out of plastic.  One of these techniques might work - Link

Pretty positive there is no difference in cornering lamps from 95-99. Hard to believe they are still available…

I DA sand mine and buff them and they look pretty perfect from 10 feet away. Needs to be done about once a year

Curious what DA you have? I bought a Porter-Cable recently but the instructions say it only likes 6" pads. I'd like to be able to use 2-3" in some areas.

I'd prefer electric, having watched a few YouTube videos about air compressors that blew up.

There are different part numbers according to my research.  According to several parts sites, they show some of the 95-96 part numbers available, but nothing at all for the newer part numbers.  I have no idea if they cross reference, or will work.  I may for sh!ts and giggles order a pair to see. The only things that STICKS out on my car is the fugly yellow cornering lens.

To be honest, Im not sure the brand. Its an older 6” orbital air sander. There are a few at my fathers collision shop but there is one in particular I like. And then I polish with a little 3” battery powered buffer/polisher. I dont put the screws in my cornering lights. They are snug with the clips and it is super easy to pop them out and clean them up whenever needed.

I bought some several years ago, they did not have holes for the lamps, that may account for more than one part number.
I cut holes in them for the cornering lamp sockets, my Riv spends most of its time indoors so they still look new.

TTT. Does anyone have any NOS lamps available? I still can't find any. It's the only thing exterior that bothers me about the car.

I looked around and didn't see them either. Even the main light lens and housing appear to be discontinued. The remaining parts had to end up somewhere, but who has them?

Moral of the story - don't wreck the 8th gen.

Many years ago another list member wrote that he got rid of the yellow aging on the cornering lenses by running them thru his dishwasher (with dish detergent). I'm not sure I believe that worked but FWIW there you are.

There are a bunch of videos on YouTube about removing yellowing from plastic with SalonCare 40. I'm going to try it in the next couple days. I don't know if it will help with our cornering lenses though. I believe the problem was in the coating on the lens. That's why I sanded the original coating off my replacement lenses and recoated with a better product.

I actually believe that the problem is the type of plastic that the morons at GM used....
Our headlights are plastic as well, yet despite the sun & the heat from running them all night they don't turn color...

It must be close to 10 years since I did my cornering lenses. The new ones haven't yellowed. They don't get much UV in the garage though, and the new coating could be blocking out the UVs that do sneak in.

I'll be curious about the SalonCare 40...  Really??

BTW, just for the data, having learned my lesson about parts obsolescence with the V8-6-4 Eldorado I think I bought new lenses shortly after I bought the car, say 2006 or 2007.  Mine has mostly been garaged as well and I just noticed some darkening early this year, bone stock.  M

I'm currently attempting to restore some 50 yr old nylon parts from my Charger with SalonCare 40. It hasn't done much yet, but they didn't get much time in the sun today either.

I've still got my original, very yellowed Riviera cornering lenses. Maybe worth an experiment?

Gears? I did some white nylon retainers from around the engine bay. Some of them came out good, some of them need another day or two. Overall I think the technique is working.
