Hey guys i am wanting to get 2 LED strips to put under the headlights (or on the front bar) of my magna and i want them so they turn on with the car but turn off with the headlights.

I was thinking about running power from the cig lighter (maybe with a fuse) to the switch and then grounding the switch.

Should this work? Otherwise does anyone have any simple suggestions ?

Just run wires from positive of battery to a switch in the car, then to the positive of the lights. Then ground the ground of the lights. You can turn the lights off manually when you turn the headlights off by the switch. That would be the easiest way. Doing it this way means you can also turn them on when the car isnt on (great for camping) :D

Wannabee Audi... :thefinger:

Well do you want some sort of in cab control or just let them do their thing ?

Should be as easy as a run of cable from the battery to the front, there's your positive, ground it near the front somewhere. Have it go through a relay that is triggered by a cable spliced off a headlight loom that should be nearby... ground the coil somewhere nearby.

Something along those lines If I'm making any sense.

im not fussed whether i have control over them from the cabin or not but im thinking if instead of having them come on with the car and do what they are meant to i think it might be just easier turning them off and on from the switch.

Then do what I said :D I did my Leds that way

I came across a diagram of how to wire them without a switch,

Does anyone see a problem with doing it this way ?

[Tobyrose12345]

Not at all..but then you wont be able to turn them on/off at will!

[peaandham]

That doesnt bother me too much, i would prefer not to have a ricer button in my dash lol.

[Tobyrose12345]

Thats ok then :) That will work perfectly!

That means they will come on and off with your park lights, it seemed to me more like you wanted to run them whilst your headlights weren't on?

If that is the case, then it may work to grab a NC (normally closed) relay, and connect the coil to the positive of your park lights, and ground. The 12v source for the DRLs should come from an ignition ON source, not ACC ideally. Then when you turn headlights on, the relay engages, turning the DRLs off. The rest of the time the DRLs just get powered through the relay. If you want manual control, put a switch after your fused connection to the ignition ON wire, and connect the other side of the switch directly to the DRLs positive, bypassing the relay.

you wouldnt happen to have a diagram of how to wire it the way you said it would you big v?

Why overcomplicate things? Why would you want them to turn off when the headlights are on? You dont drive around with your parkers on do you? They DRL's are LED and draw SFA current, no need for a relay, just wire them parallel to the park light circuit, across the globe holder. Then they will come on with the parkers. with a fuse on the power wire if you want to be 100% safe.

if its a late model car, the parkers for left and right will generally have a seperate circuit each, so just pull the parker bulb out of one side, if its an older car, pull both out so as to avoid backfeed through the filament, then connect the clip of the test light to earth, then probe the pins in the holder and figure out which is the power feed when the test light glows when the parker switch is turned on. if youre using a multimeter to do it, black to earth, red to pins, then look for 12v with parkers on.

He doesn't want them on with the parkers, that's why the relay (described by Big V) is using the parker circuit to turn the DRL off.

with mine i just plugged them into where the parker globes used to be... but do you want them to be off when the parkers are on? if so do it how big V said...

i totally started this whole audi light phenomenon, now everyones doing it :(

You wanna come to noble park - every dickheads got them.

I "think" I've done this right. (although I havent played with relays for a while and the only diagram I have is pretty complex to work out whats going on.)
Feel free to correct my diagram if I'm wrong.
