First the right low-beam died, then the left. I took out both bulbs and inspected them; they were not blown. I also replaced the bulbs and they still did not work. I checked the fuse box, and the fuses aren't blown. Thoughts?

Relay? Do CANBUS systems still have relays for the lights? Bad ground/failed ground wire? Test for power and ground at the light?
