ok people!
Is there a way to make my fog lights flash when i flash my headlights?
like when i flash to thank someone for letting me through?
i think it would look cool to have all 4 lights flash. __________________

Power feed from the headlight positive through a diode to the power feed of the fog light positive on the same side (left to left, right to right).
The diode only allows the power to flow in one direction, like a check valve. Be sure it is rated for the amperage (volts [12] / bulb wattage [55] = ~4.6 amps, so if the bulbs are 55, you need a diode rated for at least 5 amps. If you have 100 watt bulbs, you need a diode rated for 8.5 amps minimum (I'd probably go 10 amp rating in either case).
Shrink tube over the entire diode and the solder connections on each end to protect it all. It may not be a bad idea to add a fuse in this line as well (again, following amperage guide above, but try to get as close to the amperage as possible with the fuse, whereas the diode can be much higher safely).

Why not just push the foglight switch on and off. Foglights don't work with the high beams and probally would be a pain in the ass to hook up. __________________ 98 Avus Blue 318 ti Active
