The 2001 Dodge Ram headlights have +12 volts on them all time. Ground is used to switch lights and brights on. What is the advantage to using this system? Does anybody make a wig-wag for this type system? What other vehicles use switched ground?

Why can't you convert it to a + switched system with relays? I don't really see any reason why this wouldn't work....

Don't know the advantages of thet, but negative switching wig-wags are made. And the usually is no cost difference, at least I dont charge diffrently.

Do not install wig-wags on a Dodge without putting a new harness on the headlights first. The stock ones have a tendency to catch fire and meltdown when you use wig-wags on them. NAPA has a universal 9004/9007 headlight plug & wire harness you can get in stock for only a few bucks.

Then, AFTER you get a new harness, you can get a flasher that will work with a ground-side switching system

One reason neg switching is used is so when there is a short the lights will turn on as opposed to blowing a fuse and not working at all. The theory being that the lights being on and not being able to turn them off is better than not working.

We use on Chysler products a seprate halogen set up. The best thing I have used is the hideaway halogen bulbs with a standard flasher. They mount just like a strobe tube and you dont have to deal with the chasis electrical. We had a warning from the major flasher manufatuters that installing an alternating flasher could do damage to the body electrical computer.
