I just got my LED bulbs in for my DRL's, looks great, but i wanna have it on at night. does anyone know anyway to do this? i was thinking about running the power to the DRL's from the parking lights so that whenever the parking lights are on the DRL will be on. think that will work?

If you use a relay and totally disconnect them from the DRL circuit then it should work. I wouldn't just run wires because you might get feedback.

Yeh that's probably the easiest way to do it. Just make sure to cut the DRL wire not splice into it unless your using a diode or else whenever your DRL's are on your parking lights will come on as well.

is there a way to do this with jumper diodes like with the 6 high mod?

Yes. Connect the ground from the negative coil of the parking lamp relay to the negative coil of the DRL relay, band on the diode facing the parking lamp relay.

If you do it at the underhood fuse box, the parking lamp relay wire is white. The DRL relay wire is Green/Black.

If you do it at the BCM, they are at the big gray plug. Parking lamp is B2 white. DRL is B4 Green/Black.

Or if you want them to come on with your headlamps, then you can use A4 Pink/white, also at the BCM gray plug or same Pink/white at the headlamp relay at the underhood fuseblock.

just tap them (properly) into the running lights. It works great.

Chip. Did you use a diode when u tapped them? If so the gray band faces the drl side right?

I didn't use a diode, because I converted them into amber running lights.

Can't do a diode from low beam to DRL fuse?

The BCM applies/removes ground to the relays when it comes to all the lighting (parking, DRL, low/high beams). The simplest and (IMO) cleanest way is to trigger the negative side of the coil on the relay.

If you want to add your own complete circuit (power, ground, relays), than you could wire to the DRL fuse.

wow, all these great replies........... just wish they were in English!! so can i just cut the power to drl's and splice into the power going into the parking lights and run it into the drl??

It does work. That's how I did mine......and for future reference, as long as the circuits have the same amperage, you're good.

Exactly. Then tape off the old power end or pull the drl fuse for safety.

I ran mine in parallel. I feel it's actually safer. If I'm not mistaken, it more evenly distributes the load across 2 circuits, instead of overloading 1 circuit.

Ahhh I see....that would work well but your DRL's and Parking lights stay on all day correct? Do you have control when they are on an off??

I converted my DRLs to amber running lights running lights, so that doesn't really matter to me, but I'm sure we could figure it out if you needed to.

Yes, you can do this, but you must splice both the 12V and ground wire. However, if you do it this way, you will not have DRL's on during the day. They will only be on at night with your parking lights.
