I'm all about symmetry with my vehicles lighting, I hate it when headlights are missaligned, one bulb is darker or brighter than another, etc.... plus anyways...symmetry is beauty right? lol

So I'm backing up to the garage door, that's all glass windows, at my shop the other day and notice one of the bulbs in my 3rd brake light is darker than the other and putting off a slightly different pattern to the light (ie, dark spots etc..) So I'm upset that I haven't noticed this earlier and crawl into the backseat to pop out the housing. I pull the bulbs out....and there is a BIG BLACK BUBBLE in the glass of one of the bulbs??? Is there any danger to this if left unnoticed? Why did this happen? It was the right bulb, (921 18W I think.. ) so it seems like it shouldn't get so hot it'd bubble up like that.

Just wanted to bring this up just incase it might cause a problem for anyone sometime down the road. Here's a picture of the old bulbs.

eventually it will EXPLODE.

thats what happens when the bulb suface gets contaminated during/before installation. can be a REAL pita to get all the glass out of the housing.

I would imagine it was about to explode! Not that big of a deal if it did. Youd just have to shake/vaccumm all of the glass out of your headlight and remove the bulb with a glove or towel

An explosion of that caliber could have blown out his rear window. $$$ to replace that peace!!!! LOL.

Just goofing!!

Thats why you dont touch the bulbs. Looks like whoever checked your bulbs last had a greasy finger and touched it. ALWAYS use a lent free towel when handling bulbs.

I drove through a massive puddle up by a lexus dealer in my lincoln once. HAd silverstar fogs and the water got into the foglight and blew the bulb. It burnt the inside of the foglight as well.

I replaced all my light bulbs in the back of a 91 ls400 and the head lights 2-4 hours to get it all correct. I am using the new Sylvania ultra bright silver star headlights bulbs and boy they make a difference. I put in the HID LIGHTS in my 06 camry and they really light up the road. I also had problems with my third eye brake light both bulbs were dark put in new ones and they really shine now.
