2011 gmc sierra 1500 5.3L 53,400 mi, crew cab. Both of my high beam lights went out at the same time. They were working earlier in the day, then when I used the truck later in the evening they would not come on, high beam indicator on dash works. I checked the fuse box but don't see a fuse or relay for the lights. At 36,394 miles I had both high and low beam bulbs replaced.

 

resolved.

 

How did you resolve this issue?

 

Bulbs were blown.
