So yesterday I decided to see if I could clear up my headlights. They're very yellow, and when I say yellow, I mean "I can't believe it's not butter" yellow. So I searched it on the net and found out how to do it. Here's how I did it.
First you need 1 sheet of 600 grit wet/dry sandpaper, 1 sheet of 2000 grit wet/dry sandpaper (you can get single sheets at Orchard for $1.50) a bottle of 3M rubbing compound and Maguires PlastX plastic polish if you want. I didn't use it. It should cost you around $25 total and it takes about half a day. First you need to take you headlight off in order to get a better grip on it. If your doing this to your stock lights as I did, your headlights should have what look like 3 little nipples (HAHAHA...nipples) on it. I like the sleek look so I took a hacksaw and cut them a little bit above the face of the lens. Then, with a straight razor, carefully shave it down to lens level. Next, get a bucket of CLEAN water, your 600 grit sand paper, a shop towel, (I used 1 scott's shop towels) and a block of wood. Wrap the towel around the wood, then the sand paper around that. Water it down and begin to wetsand the lens. Try to sand in one direction. I went so far as to remove all part numbers on the lens. You'll want to intermitenly rinse the lens off with clean water. ALWAYS KEEP THE LENS WET WHILE SANDING!!! You'll be sanding with 600 grit for a while. When it looks like the lens has a uniform milky haze, and is free from any bumps, switch to 2000 grit. This step should take about 15 minutes. Rinse, then dry it off with a towel. Here comes the magic. Once it's dry, apply the rubbing compound in a circular motion per directions. I applied and buffed 4 times. Each time it got better...and BAM. Clear lens. I have Silverstar Ultra's and thought they where crap until I cleared up the headlight lens. Now it's twice as brite and I now know why people like the Silverstar Ultra's. Sorry I didn't put step by step pictures like "poor mans throttle body" did. Haven't figured out how to do that yet. Here are some before and after pictures. Any questions? Just ask.

 

Will have to try this, my fog lights are brighter than my head lights.

 

wow, dems nippuls wuz nasty.........

 

I hate to say it but they make a kit at AutoZone for like $16-17 that does the same thing. However, I still have yellow headlights and haven't tried either method so maybe your way works better. I don't know.

Anyways, they look good! Nice work.

 

here's another simple and cheap way. get a small container of "rubbing compound". looks and feels like wax, but has a little more grit. use the buffing wheel on a dremel tool with medium speed. smear on some compound and buff it off clean. repeat 2 or 3 times. i did mine about 2 years ago and they've stayed clear.

 

Can you do the same for fog lights? Mine are getting yellow.

 

The main reason I went this route was because my lights were heavily yellow. the pictures don't do them justice and I wanted to use a tried and true method. Do it right the first time and they'll be no second time. Here's the site were I learned it from. there are a lot of before and after pics from top to bottom.
