Last night I finished installing an H4 housing kit so I can use an led bulb in the future (right now they have halogens in them) and noticed an issue I don't remember having the last time I drove the car. For some reason the right headlight works but the left isn't. The car is giving half power to one high beam (the left) and full power to the right headlight. I haven't pulled the high beam switch, until after when I tried to get it to go off. If I pull the switch both high beams do what they're supposed to, but the one high beam is going on dimly without pulling the high beam switch and turning the headlights on.

 

You have an incorrect connection... double check your wiring/ head lamp connectors.
