Burning out my headlights?

I'm having weird problem. Last week one of my headights burned out. I didn't think much of it other then that it seemed premature because I replaced both of them a year ago. Well... just yesteday the other one burned out as well. I replaced it too. The original lights lasted for 13 years. The last set lasted a year.
Also- last year the battery in the truck started leaking acid. It was coming out of the top. I thought it might be overcharging so I took the alt in to a shop to have it tested. It was testing as within proper voltage.

So my guess is that either the lights were a total coincidental fluke or the alt is in fact bad and the equipment that tested it was wrong. Its weird because the lights arent any brighter than usual and nothing else is burning out either. The replacement battery is fine as well.

 

Id check for moisture in the bulb housing

 

You remembered not to touch the glass on the bulb with your bare fingers right?

 

I had the same problem with a replacement set of headlights I bought from wlt world and they burned out very quickly. But I got another set and they seem to be working better.

Good luck

 

This.
Sometimes this is the problem...the person replacing the headlight bulbs touches them. This will make them prematurely break.

also check for moisture in the housing. I have broken a bulb off roading because water splached up into the housing and onto a bulb.

 

Yep, when changing those Halogen capsules you gotta be just like a surgeon & never, ever ,ever , NEVER ! ( did I say never ? ) touch those little gems with your bare fingers,hands or any other part of the body that has amino acids on it, Get some of those rubberized throw away surgical gloves before you even get the replacement elements because bigger than shit, no matter how careful you try to be, if you don't have the gloves on first I can practically guarantee that you'll get finger prints on them some where & you'll be replacing the bulbs again in a few days. I did this a couple times before realizing that I was fucking up by touching them with bare fingers.....

 

The oil in your fingers get on those bulbs and they are toast. I hold mine by the prongs on the H4's.
