mabey a relay if you tested the wires with a multi meter and there is no power it can only be a fuse or at the light switch check there

Could it be the switch if they dont come on initially, and eventually come on during the drive?

My headlights in my 2015 GMC Sierra will intermittently blink off and unless I stop and turn the truck off and on and turn the knob off and on they wont come back on. It will go for weeks without issue then all of a sudden it'll start acting up again. Dealership says they've never heard of such an issue. Changed the bulbs. Help???
Having the same problem has anyone figured this out yet
