I have had my 04 hyundai sonata since December of 07. Since then I have replaced my low beam lights over 25 times since I have owned the car. It doesnt matter what brand, they all burn out in 3 months or less. I have taken it to the dealership and to two other mechanics and they all say there is no short, yet the bulbs keep frying. At 20 bucks a bulb, the neverending cycle of replacing bulbs is getting expensive and ridiculous. One burns out, so I replace it, then the other side burns out, so I replace that. Less than 3 months later the cycle starts all over again. I even had 2 burn out in a month and a half. I dont know what to do anymore.

 

What brand light bulb you using, and where you buying (not that where you buy them really matters)..

May look into buying European sourced bulbs, OSRAM or HELLA might be worth a shot.. and give them a test drive.

 

Are you touching the bulbs with your fingers when replacing them? If the oil from your skin gets on the bulb they will burn out quicker. Never touch the glass part of the bulb at any time.
