UV protetion for Polycarbonate Headlight housings?

[Dave M]

Greetings,

New Guy here. I am concerned about the deteriorating effects of UV rays on the polycarbonate lenses of the HID headlights. I'm hoping to avoid, or at least forestall, the dreaded yellowish fog that so often clouds such lenses with age. Do any of you wise and resourceful veteran Prius owners have any suggestions? I don't think wax is enough to protect my new '05 black pkg 6.

Thanks,

Dave M

While Keats said, "A thing of beauty is a joy forever" you might want to look at some protection for your lenses and expensive HID headlamps to keep them beautiful, such as these or a similar paint/lamp protector (see lots of threads here about clear bra, etc.) With a Black Beauty, you might want to consider protecting the paint too.

After some further reading here I came across reference to 303 Products which look like a good UV shield.

I hope this helps.[/font:4ef7085fdb]

303 kicks! I've been using it for about 13 years. I have yet to find a better product!

Yeah 303 Aerospace Protectant is the best. Use it on all plastic, inside and out. I apply to the exterior lights and plastic trim after every wash. It also keeps wiper blades like new for years!

Don't use wax on plastic or rubber, it's bad for it.

I also found PlastX by Meguiars great at buffing scratches or dullness from clear plastic lenses. It's specifically made for it. Use it, then coat with 303 for maximum protection.
