ok so my headlights were in pretty sad shape for awhile, the housing were alll messed up and only one bulb worked on low and the other worked on high, so i got new housings and bulbs for it, now when i use my high beams after about 5mins they start to flicker on and off,

i unplugged the passager bulb and it stop, i then replaced the pig tail for that side, still had the same problem and didnt help, last night i replaced my high beam-blinker-washer switch and i still have the same problem, i also bought another set of new bulbs and they still flicker on and off when on high

is there a relay i cant find for the head lights??? or could i just rewire my high beam switch on a relay of my own?
