Yellowed headlamp inside headlight assembly

Recommended Posts

The driver side headlamp (the part inside the assembly) has a small yellow spot just in front of the bulb. The bulb still works. It just looks unsightly. I would like to clean off the spot if only for aesthetic purposes.

How do I dismantle the assembly?

I took the headlight assembly off the car. Now, I need to separate the black casing from the clear plastic cover to get inside the headlight. There two screws on one side of the casing and three plastic snaps on the other side but they only keep the rubber seal in place. But I can't see how else the assembly is kept in together.

One slip with the screwdriver tip and you will have a nice permanent scratch! If it is yellowed from the heat of a bulb then you have little options. But if its dirt then I would use a soft wood dowel with the end rounded and sanded. Attach some soft terry cloth with 3M Super 77 spray adhesive and then use a very fine plastic polish to gently scrub away the spot.

Thanks GoldenWarrior1.

I tried that. I didn't have a dowel but I cut a thin strip of wood off a paint stir stick and taped a strip of micro fiber cloth to it and dampened it with PlastX. Unfortunately the yellow spots didn't come off as you predicted. It must be melted into lens. It was worth a try though. My only alternative now is to replace the assembly. I looked on Ebay and there are lots for sale. Around $500. I don't think its worth replacing at that price considering its really only a cosmetic problem. But I will keep looking around. Might attend some swap meets in the summer.

Thanks again.
