Default headlights are out

Hey all
Well both my headlight went out simultaneously.
All the other lights work.... headlights no workie.

I looked at the switch and noticed it had a very light green light on (which if I remember correctly, when it was working correctly I think it was a bright orange light... but I could be wrong)

Anyone have any ideas?
Its 703 saturday night so of course I cant go out and fix this....
but right now my only thought is possibly a relay?

Also where would it be?

Also, could the passengers side floor board getting damp effect it? It rained here and it leaked and it made it down to the floor board and down to the hump the seat is on but no flooding or standing water, just the right side of the floor board on the passenger side.

Given they worked yesterday, and it rained like days ago....

I would check the fuse first then the relay next. The light on the stalk inside is on a different circuit.

Have you done the drl modification in the fuse block that many guys do? If so I would be looking there first. Seen many internal fuse block failures due to this.

The mod I was reffering to was if you power up the drl relay with the headlight relay signal so all 4 lights are on at the same time puts more draw on the headlight circuit, not to mention some peoples wiring skills can be sub-par and also cause issues. That's why I always look at electrical modifications prior to anything else.
