LED headlights alfaOBD and resistors?

[aszumilo]

Guys, one last thing - can you help me identify which reverse bulbs I have? I want to get these swapped out to a brighter LED. The numbers on the bulb don’t match anything I can find.View attachment 538938

Think those would be Sylvania 921LL

Not sure which headlights I have, but it's a single bulb for the high and low beams.

If it's a single bulb that does both High and Low beams, those headlights are commonly referred to as Duals. I don't think Duals were installed after the 2012 model year.
The Express trim level truck came standard with Quads for 2015, the Projectors were available as a package option. Have pictures of the available OEM headlights:

Projector:


And these are Duals:

Nah, I've got quads. My mistake.

When I swapped my 17 to all LEDs, even after setting up everything in ALFA obd, I still had to use resistors on the taillights. For the flashers to work right I think. It wasn't hard.

Were you also experiencing the headlight flickering before setting 'enable high intensity discharge headlamps' in AlfaOBD?

Actually, I set that in Alfaodb before I fired it up m
