Cleaning out the headlights?
« on: February 26, 2018, 06:46:26 AM »
I can't be the only one here who's dirtied up the inside of thier headlights by offroading through deep water crossings.  My passenger side light is especially bad with the entire silver reflective interior coated in brown.  I have tried to pry the lens apart from the body but I have managed to crack the plastic a little and chip the edge of the glass.  Its on their good but I was hoping to pry the lens of and clean everything up before resealing it all.  Has anyone here had success with this or did you just get new light assemblies?

I've never done it (never needed to), but it's my understanding that most headlamps can be separated into the front & back sections after heating in an oven - you tube will probably get you more specifics, like temp, and how long to bake for.

I have used a heat gun to heat up the stuff that holds the glass lens to the plastic housing (concentrate the heat on the glass lens, not the plastic housing). Once heated sufficiently, I pried the lens off the housing. From what I recall (been several years ago, the last time I did it), I didn't have to use any additional sealant when I put it back together. Just heat it up again, to get it sticky, then push and hold the lens onto the plastic housing, until it cools off.
The reason I was doing it back then, I was replacing broken lenses on lights that had good housings (I was using good lenses from lights that had broken housings).

While you are in there, you might try to figure out what you need to do to prevent water intrusion in the future. Headlight bulbs should have an Oring on them, and then a seal of sorts on the marker light bulbs. With everything in good repair you should have a water tight enclosure
