I recently bought this pickup and it has some sort of aftermarket headlamps in it that have fans on each of the bulbs. The high beams don't come on. When I actuate the highs it just stays at low beam.
I pulled the left headlight and did a test with a meter on the headlight plug leads. There is a voltage change but I can't understand it. All that shows me is the switch in the interior is probly OK.

Since both High beams are not working, I imagine it is a relay?
Is there a separate fuse for left and right headlights or a separate fuse for high and low beam?
(I searched all over trying to figure out this fuse situation. I can't even locate the head light fuse. I know its in that TICM but which one)?
Same question for relays.
Is there a separate relay for high and low beams? (Or even a relay at all)?

Clearly I don't know what I'm doing.
I could sure use some instruction here.

Thanks for any info,
I appreciate it!
