yellow ish headlights
really yellow ...
Meguiers PLAST-X is a fairly decent product. There are better ways, but for a beginner, or just starting out I suggest that product. Make sure you tape off where the headlight meets the body with blue-tape since the plast-x is a mild adhesive.
This will all work if your headlights are yellowing from the outside. If it's from the inside, you would have to pull them apart and do it from the inside. There are also wet sanding options are available. But be-careful with that.

it depends...you can waste time and money removing the yellow form the outside..but if the tarnish is in the inside its a bigger project than expected..ive delt with g HLS for quite sometime and found that the inside of the lenses have a clear protectant that sometimes fades,bubbles,and rubs off in some spots. best way to fix is baking the hls,seperating them,then sanding the inner lense with 2000gritt sandpaper then buff using a plastic cleaner/buffer..i also found that chrome/wheel cleaner removes the clear on the lenses the best..if interetsed send me some pics of your hls..if your g isnt a DD and you can send your hls ill clean them for you cheap..just shoot me a pm,mike.

Plast-x only works till the next time it rains.
Borrow an random orbit buffer and get some cutting polish. Read into polishing techniques then polish them up and use a sealant or good wax and they should stay clear for a long time!
Last resort (if the lights are completely demo'd) you can wet sand them. Google that, probably not the best idea, but still an option.

If you can clean them up via Plast-X it will be fine. I recommend going less abbrasive and ramping it up. I would try an oxidation cleaner such as Klasse AIO first, than up to a light cut polish like Meguiars Plast-X, than a medium cut polish by hand, then medium cut via a polisher (orange/PFW), then a heavy cut via hand/polisher (orange/PFW), and then finally wetsanding (3000 unigrit to start). All this is to minimize unnecessary removal of the surface.
Just remember to seal the headlamps. I would not put a wax, an acrylic sealant such as Klasse All In one followed by Klasse Sealant Glaze would be best IMO (remember to redo the combo every 3 months or so) due to the many benefits they have over a wax, both in durability and protection.
Ohh, kinda phrased that wrong!
What I meant was why bother buying plastX when you could just buy a multi purpose polish and use it on more than just your headlights.
Not like Plastx won't work on paint...but I wouldn't use it. Just make sure after you polish, you seal it!

Nothing will stop the headlights from yellowing, especially if you park your car outside and live in the north or in really sunny areas of the south. Salt and sunlight really eat the hell out of the plastic headlights. I find a good cleaner wax or plast-X and a buffer once every 2-3 months keeps the "like new" look alive. LaminX protective film is another great way to add life to the headlights.
Word to the wise - if you like to really scrub away at the headlights or buff the headlights for a long enough time to get them hot to the touch, you can potentially break the sealant ont he headlights, then you expose the inside of the headlight to the elements and they start rotting and corroding from the inside. So don't be too rough when cleaning the headlights. You could make a bad situation worse. Klasse AIO does not get the headlights as clean as plast-x does. Both work, but Plast-X works better. You may as well throw some Klasse sealant glaze on the headlights when you are done.
