Headlight upgrading
I recently changed my factory halogen headlight housings with an aftermarket halogen set with switchback planks. Doing so I had to switch both my high and low beams with H7 bulbs. I went ahead and went a step further and ordered all GTR led lights from Headlight Revolution. After the install everything worked great. I don’t know if I didn’t notice prior but I thought the factory lights had all four lights running. (2 on each side) but when I engage my high beams, only the two top lights engage. Is there anything I can do to get the lower two H7’s to engage their high beam as well? Sorry for not paying attention ahead of time but I figured all four factory lights lit up all high beams as well. Thanks for any future info or leads on this matter.

there’s a forScan change to keep low beams on with High Beams as well!

Which aftermarket housing did you buy? Sounds like there's some wiring internal to the housing that's causing the issue. I wouldn't just make a change in Forscan without understanding what's really going on with those housings.
The housing sounds like it's set up so the tops are aimed to be a high beam pattern and the lowers at the low beam pattern. Having the low beams on with the high beams is just silly in my opinion. With the high beams, you want light to project out, not dump right in front of the truck.

Headlights are resolved
We were actually able to get what i was going for. It was in the BCM (non as built). So now all four lights light up in low beam and all four lights flash over in hi beam. I did however need to adjust every light upwards. I didn’t realize they were pointed at the ground as much as they were. Yes 4 of those gtr’s is bright af! With or without hi beams on, not to mention having the same type of fogs. Very happy to say the least.
the only part I never figured out was how to get the planks to only light up in DRL. The lights I have have the turn signal plugged into that part of the light. Even though it acts as a parking light as well. Oh well, I’m good where I’m at.
someone asked what brand these were, I’ve done three everything away. They came from Americantrucks.com
