What type of bulb did you use? LED or halogen? I ask because the LED bulbs require rotation to get a good beam out of them. You could try rotating the halogen bulb, but I doubt it will do anything. Also, check to see if one of the headlight tabs broke while tightening or possibly the piece of guide plastic isn’t in the slot (not sure if your year has it). 97-03 has the inner tab that slides into a slot on the core support, behind the grill a tiny bit.
