headlight switch upgrades?

My 76 02 has H4's rated at 55/90 watts. The 76's

have headlight relays, right? So it was surprising to

see a wisp of smoke curl up from the dash during

a long drive with the lights on. Nothing outside the

switch melted but the switch bezzle was pretty hot.

I've heard that the switches are notorious for

burning out. I don't think the electrical draw is

excessive. Does anyone have suggestions for a

switch upgrade?

high beam relay, only low beam. It that's the case, those 90watt bulbs are waaaaay too much juice for either the headlight switch or the dimmer switch. Wire in a relay ASAP or you're gonna fry something!

but Mike is correct that the 90-watt bulbs draw too much current for the original setup. Looks like the high beam current goes through the light switch. You need separate relays for your high beam bulbs.

Evil BMW eletrical trick numero uno -- put fuses and/or relays in a circuit, but on the wrong side of a switch. They must not get enough fireworks in Munchen...
