When you sand, make sure you start with the least aggressive. I'd stay away from anything courser than 1000 grit. Anything courser will be difficult to remove the sanding marks. I made the mistake of using 500 and despite being really clear from yellowing UV coating, I see a lot of sanding marks esp when the lights are on.

I pulled the trigger and bought new OEM headlights (housing only) OSRAM CBB HID Bulbs and Peak Profile LED for highs. Going to protect the housing with Xpel... going all in!

 

Keep in mind that if the lenses have cracks throughout the depth of the entire lens, they probably aren't salvageable.

 

Unless 150 people sign up at $150 with prepaid orders, I wouldn't even cover the manufacturing costs.

Chinese companies can crank out whole headlights for cheap because it's what they do on a large scale. If I (not a plastics manufacturer) get them prototyped, developed, manufactured, and shipped, it will cost significantly more money, even in China.

 

What about contacting the headlight manufacturers and get them to sell a batch of the lens alone?

 

I think the previous comment about lenses were about the housing lens, which the UV coating turns yellow.

What you're referring to are the projector lenses.

 

I'm not sure what you mean here. Does that flickering issue occur more with the fresnel projector lens, or with the clear projector lens?

 

Fumes from 2k are extremely hazardous to your health; don't go recommending this to people when it's both dangerous and unnecessary (most don't have the proper ventilation masks).

A small squeeze of Meguiars Ultimate Compound, a microfiber cloth, and 30 seconds of rubbing will make your headlights look factory new. It takes a few months for them to fog up for me, but if I wax them (as with the body of the car), then they last without a clearcoat.

Meg Ultimate Compound: Collinite 845 wax:
P.S. My bulbs, I believe, had 120k miles on them and were 14+ years old. They do get dimmer. I swapped new HID bulbs in per OEM specs and things are indeed brighter.

 

i apologize. next time I’ll make sure to include the fine print. Or are we assuming that people can not read warning labels on spray cans? Or that a $30 mask is somehow unattainable?

and sure you can use good ol’ fashioned elbow grease, compound and get foggy, hazy headlights every few months. Oh and spend extra time waxing just to delay the imperfections. Or you can restore headlights properly the first time and then apply a clear coat or film for protection and long lasting results that will definitely be more impressive than compound applied by hand... The time it takes to do it once correctly is far less than sitting there rubbing away with compound followed by wax then rinse, repeat every few months....

oh before i forget please use a mask and secure proper ventilation!
