Scratched Headlight Lens replacement

Bought on Ebay two clear lenses, for my 2011 X-5 m sport 5.0. was told these are OEM, but from HK, well, they look fine.

Reg. mechanic says he won't touch 'em. Grrrr. My existing lenses just have been polished too often, kind of wilted, scratched/discolored.... Watched several You Tube vids but they all look and sound like idiots!

Any recommendations who to go to, who does this, So CA, Ventura area? Cost?

Anybody DONE this? Using a Dremel saw to cut them out along the edge....? Really? or drop entire assembly for 12 minutes in an oven at 200ļF, also I question THAT wisdom.
Appreciate your thoughts, THX

Quentin

Try a body shop rather than a regular mechanic. Insurance companies will specify just the lens if it is available and the other parts of the headlight are undamaged, so a body should be pretty well versed in the procedure.

FWIW the oven trick is well known and successful on the E46 side. The heat basically softens the sealing material so you can cleaning pull the lens. It depends on which headlight version you have on the E46 and I don't know enough about the E70 headlights to comment as to whether it will work or not but if the lenses are sold separately and there are tabs, it should be doable. Hairdryer on high is other method.

Hi Quentin, in my experience, almost nobody wants to mess with this procedure due to the complexity and high-likelyhood of leaking/water ingress afterwards.

I did the work myself once when retrofitting a projector lens on a Toyota vehicle. I put one headlight assembly in the oven and used a heat gun for the other. This softens the Butyl glue that seals the lens in place so you can remove it and replace. You will need a roll of new Butyl tape to put in the lens.

Definitely not an easy or clean job. Good luck.

You said the lenses have been polished too much and are scratched/yellowed. Have you tried a restoring kit with sanding pads? The 3M one worked well for me and lasted.

I just bought this and will be doing it soon. https://www.chemicalguys.com/headlig...LEX_443_9.html

OP, maybe buy some used junkyard lenses and restore those? If anything goes wrong you still have headlights. #twocents

This guy used to be big into the headlight modification and he can easily swap the lenses for you

Before and after.

This took 2 beers and 3 hours. Started with 2500 wet sandpaper and ended with carnauba wax.

But do they give you BEER? HUH? No, they don't.

I goggled and couldn't find Costco doing it but Sams, yes. Sounds like they give it a quick wet sand then apply some kind of UV coating. And the price went up to $49.95 I spent less.

I donít know if you guys detail your own cars but if you do, follow same procedure for your lights as you do your paint.
I usually clay and wax once a year and just wax once. I always hit the headlight lenses and tail lights and Iíve never had to do anything more to my lights. I donít know if the automated car wash chemicals have an impact, I suspect they might. I prefer to drive a dirty car until I can hand wash it than taking it through the scratch master.

Just took picture of the 18 year old e46 this week after hanging those cabinets. I bought that car new and itís had zero body work so that headlight is original.

FWIW: Ive put on an Xpel headlight film after polishing. Provides UV protection as well as pitting/abrasion resistance.

Do these come pre-cut to shape?
