When i was driving home last night i realized that the right headlight was out. I switched on the high beams and they work but when i switch back to low beams the light goes out again? What gives? It isn't a bad bulb, right? Is it a fuse?

 

Blew the low beam coil?

 

This is totally normal, the bulb has two separate filaments, one for high beam and one for low. the low beam usually blows out first (since it's the one you use most.)

The solution is that you need a whole new bulb. (Sorta stupid, but that's the way it goes.)

 

He's right, my friends car had the same thing happen to it. He just bought new bulbs.

 

i agree, defintly the bulb. i've had it happen to me.

 

9004 are dual filament bulbs, it also happens to my bulbs in my brake lights, you just need a new bulb, no biggie

 

duh..yeah..new bulb--yesman #5

 

wipe them down with alcohol and don't touch them before you install them. The oils from the skin will decrease the life of the bulb

 

thanks guys!

 

sound advice, my friend actually had a bulb explode in his car because he didn't listen to me when i told him this.
