Recently replaced the factory fogs with driving lights. They worked with the low beams for about 8 minutes and then the driving lights went out. Turn off the low beams with parking lights and they are on. Likewise, switch to high beams, they come back on - which is preferable - of course. But have you ever heard of too much current going through a relay and selctively switching the lights? My wife's Subaru is designed to that with her fogs (but its the opposite, go to high beam and they shut down). Time for a new relay or another great 914 mystery?

Bueller? Bueller? Bueller?

not sure why that is happening. I'd found the fogs are wired right off the low beams at the fuse panel. I'd used H-4 bulbs in some Cibi driving lights and just unplugged the circut from the low beam and hooked it to the high beams and it's worked fine. Not sure what you may have going on.
