I am installing new Hella 500 fog lights and don't understand why I have to tie into the headlights. I want to be able to use the lights Independently of the headlights. The instructions show tying into the high beam headlight wiring. Can I skip this step? Any help would be appreciated.
I went to Hellas web site and found different instructions. They say that for off road use only tap into parking lamp wire to operate lamps independently from high and low beams. Parking lamps must be on to operate. I can live with this setup. Thanks for the tips. My CJ7 would not run without this website.
Notice that they said "Off road only"! Some states require fog lights to be wired to operate with low beam headlights only. Due to the way they are focused and project light, I can't think of any situation where you would want to operate only fog lights and nothing else. They are designed to compliment low beams by shining low, close and wide.
Also, you really should run their power through a relay. If you put them through the parking lights they will always be on with ANY lights. If they are high power bulbs I doubt if those parking light wires will supply enough current, unless you use them to just operate the relay (with an independant switch).
Beer is the answer - it doesn't matter what the question is!
I hooked the relay trigger wire to a "key on only hot fuse".Then put a toggle switch in line with that to the relay.Of course the other side of the relay is hooked to battery pos. and fog lights.That way the relay is only pulling minimum power thru the toggle,but full power directly off battery.
The Hella kit came with a relay. The switch needs a small current to work the relay. The install was not bad and the lights work great. Went offroad last night and was pleased with added light. I may convert the headlights to a relay as well.
