I'm alittle confused. while driving yesterday at dusk, my driver side DRL blew, and the orange 'DRL' light came on. My confusion is, do I just replace the center low headlight bulb. I believe it's a 9003. Both my low and high beams work fine.

 

I JUST did this on my Canadian (Of Course) GE.

The High-beams/Low-beams are on a single bulb. They have 2 filaments. The DRLs use the High-Beam half of the bulb. So chances are you have a missing high-beam and DRL, but low-beams are fine

My advice would be get the cheaper longer lasting ones, instead of the hot burning but brighter ones. As you use them MUCH more than 200 hours as the package says.
