Default What causes this?

I had came back from the track yesterday morning and when i got back home i parked in front of my house, so i wouldn't have to move my car when my wife leaves for work.

As i was backing up i noticed the red light wasn't that noticeable on the right tail light (it was 6am so the lights are bright in the dark). I get out and check and sure enough the light is out.

As i take the light out today i notice this:



This is actually the second time that's happened. The first was years ago, and i didn't think anything of it, since it was the 1st time i had to change the bulb on it.

So now i have to go to the yard and get a new light because it doesn't snapturn like it should (hopefully i can find some extra goodies). Maybe it's time to switch to LED's? i'm guessing those shouldn't generate that kind of heat to melt the damn plastic like this one.

What brand/type of bulb did you install?

A couple of years ago I installed Sylvania Long Life bulbs. They melted holes in both taillights because they burn whiter and hotter.

I use my parking lights and driving lights as DRL, so the rear taillight is always on when I'm driving. Sylvania reimbursed me for new taillight housings.

When I went back to a stock incandescent bulb, no more melted housings.

replace both bulbs. Is one brighter than the other?

I'm going to guess it was a bad bulb. You could put a voltmeter and make sure the voltage is the same on the left and right side.

i had replaced them at the same time a long time ago, they were both the same brightness. Now that i think of it and remember, i had to replace this one twice. same problem with the melted plastic.

i think i should get LED's

Where did you buy the bulbs, and do you still have your receipt?

Are you using dielectric grease when you install new light bulbs? I have using Sylvania Long Life bulbs for years with no problems.

the problem is circled in blue. since the base is broken and seating incorrectly, the bulb is sitting in the housing crooked, cocked to the side, and is then melting the housing on the plastic.
