I went and checked my headlights, they were replaced 34 months ago, Silverstar Ultra's

 

Heat + vibration = broken filament

 

ironic: one of my headlights is now out. ...but I'm a little skeptical: my brights aren't working either (the blue light on dash lights up, but the lights don't get bright). So I'm wondering if my recent disassembly of fuse boxes has something to do with that. sigh.

 

The dashboard is controlled by the BCM, not an old fashioned analog wiring.
