i put the the hyper yellow 2500k nokya bulbs in about 3 months ago and now my passenger side fog light is out but when its on high beem it still works. u guys think i burned out my wiring harness or its jus the bulb???? The dealer said a lot of people put after market bulbs in and burn out their wiring harness all the time!!! any info would be appreciated

 

It depends on what bulbs you got. If you got the standard 60/55W bulbs then it's just a $hitty bulb but if you got the bulbs with a higher rating than that then it's recommended you replace the harness with a hightemp one.
