posting in urgent because ive already been pulled over and given a warning for it -_-
Alright so passenger headlight has VERY low power going to it, i had HIDs on the car but i noticed one wasnt working so i put normal bulbs in and passenger side is just barely lit, it looks off from more than 8 ft away, low beams and high beams both having that issue on pass side.
turn signals all work fine, thought switching bulbs would make a difference.

Also i just finished installing an acura TL dash barely 2 weeks ago (pics soon) and the headlights have been working fine until 2 nights ago.

Any ideas where to start?

Check voltage at the HL connector.

Then check voltage from the neg side of the HL connector to battery neg

Then check voltage from the + side of the HL connector to the battery +

You should, but you won't.

I probably should have said this, but check with the headlights on and the bulb plugged in.

Check your fuses. My buddy had the same problem until he swapped out his fuse

Check and replace as needed the 20amp headlight fuse(s) in your engine bay fuse box.
