Default Headlamp glass replacement

On a night drive home from Sedona, I heard the sickening "PING!" of a rock hitting the headlamp. So I've now got a quarter size star ding * just off the center axis of the headlamp glass. The rock did not penetrate the lamp assembly. Fortunately the headlight still works.

Anybody have a write up on headlight glass replacement? Thanks!

Apart from replacing the complete headlight not much choice.
I do have a replacement H4 lens in the works that is nearly ready for trial installation.

Roger, I do have an H4 not currently installed that could be used for that trial.

After installing your new headlight, now would be the ideal time to cover the faces of your all of your front light face's with Expel:

Would there be any work on replacing the "mirrored" section as well? That seems to be the issue on the ones I have - the lenses are fine but the mirrored portion is flaking/rough.

So I replace the whole headlamp, got it. I replaced the bulbs inside the lamp when I purchased the car, didn't know the glass/headlamp was replaced as a unit. Sorry....NOOB question.

Thanks guys.....where's rogers number?

Brian / Van
Someone (MrMerlin or Sean IIRC) has posted on here that if you put the headlight assembly (glass / reflector) in the oven at a certain temperature the sealant holding the glass in melts and the glass and reflector can be easily separated.

I have a pair of lights where the reflector is hazed (from water sitting in the light with the lights retracted) and the bulb shield is all corroded. As I have a spare pair of new lights I will on eday get around to trying to remove the glass and clean up the reflector / shield. If I stuff it up - nothing lost.

I would happily test the H4 replacement!

That said- this thread made me go learn about tin/silver re-silvering of mirrors, and I'm figuring out how much heavy metal waste I can generate and not **** off the EHS folks at work.....

Looks like it would be reasonably straightforward to properly re-mirror the insides of H4s and H5s if the lens can be removed non-destructively. And Roger has already accomplished that.

I used a heat gun to melt the sealant and very carefully separated the two. 3M makes a marine sealant that is a similar color. Not that difficult. I suggest using doing it over a shipping blanket incase something slips
