It’s been a while since I finished this upgrade, but I don’t THINK I made any changes in AlphaOBD for my headlights.
If you only changed your high beams to LED, you may be OK with the housings you have. What I found was that the stock quad housings threw light everywhere, so I was blinding oncoming traffic even on low beams after I swapped to LED’s.
Low beams are where I felt like the truck needed an upgrade the most. I couldn’t drive through my neighborhood after dark without worrying about running over kids that I couldn’t see. That’s why I went to the AlphaRex housings and upgraded to LED’s in the low and high beam. The pattern of light this setup throws isn’t perfect, but it’s good enough for me.
See, I've had the opposite experience with oem quads and leds. The leds I've used (on the cheaper end) have all produced halogen beam patterns, just brighter, with no glare above the hot spots. Even with hid, it was the same result, solid hot spots, minimal to no glare above. In fact, I had fewer people flash the high beams at me with quads than with the projectors I currently run, even though they are aimed lower, have a much crisper cutoff and running the same hid ballasts. Here's a pic of the cutoff/beam pattern with oem black quads and I believe auxito q16 led bulbs. Yes, there is some light above the cutoff, but it's not enough to blind anyone, kind of like how a projector has a small amount of light bleed above the cutoff to illuminate overhead signs. The quads, when aimed right actually produce a hell of a beam pattern for a reflector housing, without a lot of light scatter above. Now, aftermarket housings that look like oem, are absolutely terrible and have a beam pattern that is so scattered, that even with halogen bulbs, you'd be blinding oncoming traffic.
