Default Re: 12v Headlight problem

I finally got around to finishing the research, starting with purchase of a Sylania H6024. Sorry but I don't recall the manufacturer of the near idential bulbs with problems. Recall those problem was that the dash speedometer RED hi beam indicator light, lit on both hi and low beams positions. I'm a mile away from my garage and will get the mfgr data later (and post it here).


Bottom line, the Sylvania has totally indepentant halogen high and low beams filaments within the bulb. The generic over-the-counter halogen 7" blub have a common something so that when applying voltage to ground and low beam terminals, 12v squirts from the high beam terminal as well even though no voltage was sent to that terminal from the switch.


Time to order a matching bulb for the other side.
