My driver's side bulb keeps going out, but my passenger side has been fine. I run Astra hyperwhite bulbs, and at 12.50 apiece they're getting expensive to replace

 

I've gone through 3 pairs of Hyperwhite bulbs.
I used to have CUZO and some "Japanese" brand kind.
The CUZO lasted 6 months and 2 months.
The "Japanese" brand lasted a little less than 1 year.
You should get the low wattage bulbs, the ones that output 55W or so.

I would suggest going with Sylvania "stock" bulbs.
All Hyperwhite bulbs will blow out sometime or another.

 

My situation may be different, but have you tried pounding on the light? I thought my light went out but noticed after hitting it, it would return and stay on. obviously, something is loose in my situation and I've tightened everything down. Regardless, half the time I start up my car, the pass side light won't come on.

 

I've had the exact same problem every since I've owned the car. Matter of fact... my drivers side is out right now. I've owned the car for close to 3 years now and I've had to replace the passenger side once *about 2 months after I bought the car* and I've replaced the drivers side 3 times... once I fix it this time it'll make 4. I use the regular stock bulb from Wal Mart. Sometimes the light will come back on if I tap on the bulb housing but that only fixes it for a month or so. I even bought a complete new set of foglights earlier this summer to see if that would take care of the problem but evidentally not

Wonder whats up with that? I'm always sure not to touch the bulb itself like recommended on the back of the package
