lrgnation

Okay here is my problem now.

Turn on headlights. Start to drive and random times the passenger side shuts off. I checked all the connection, wiggled the wires, knocked on the light. And it would not go off but i start driving and randomly it goes off after a few seconds. Turn the lights off and back on and there is no problems. Also no problems with high beams. Its not the bulbs because i switched the bulbs from one side to the other.

wtf is happening? bad relay, bad switch? help me..
