I didn't get much feedback from a previous post, but I'm looking at the headlights that are sold as replacements that have halos on them that function as daytime running lights. They all seem to mention that special wiring may need to be done but I'm not sure what or how. I've checked youtube for some videos but am still not clear. My 04 does not have any daytime running light function. Does anyone know how these get wired to function that way or if it is possible? Or would I have to wire the halo's to the parking lights and they would only come on when I turn on the parking lights? This, of course, would also keep my tails on and I don't really want that.

I'm not stuck on these lights but my son really likes them. If there is no real way to get them to function as true DRL's, I'll probably just go with some smoked housings or something.

 

From what i remember you can either run the positive to a fuse or tie the positive into the power wire going to the light.
If you run it to a fuse the "Halo"comes on with the truck.(I have Mine like this)
Sometimes i dont run my headlights when im supposed to and just have my fogs on with the "Halo" Lights on. But if you just tie the positive into the power wire going into the Headlight it obviously only lets the lights come on with the Headlight, i thought that was a waste and thats why i ended up running them to a fuse. Only trick is you have to find a fuse that dosent get power until the key is turned.

I hope that helps a little

 

I have never had anyone ask me enable to them before, so I can't confrm or deny this. It IS an option on a bunch of other models though. This was a release from 2004 >>>

This is how they are driven

It would be nice if DRL was a separate output circuit but it's not.

 

I have access to a StarScan Tool and have "played around" with settings on my '04. I can confirm that DRLs can be turned on by selecting Canada as the country code (as well as some other countries on the list as well).

But no, there is no independent setting for DRLs on the '04 as there is with the TIPM models (06+). Sadly for me, there is also no setting on the '04 for fogs on with high beams (which is why I have the DIY wire in the FAQ section). With the TIPM models you can enable that feature as well...

 

Hammer, I did your fog mod and still have it configured that way. So, they come on even when i turn on my parking lights. I don't want the headlights to function as DRL's, just the halo's/LED's. They come with separate wiring but I'm not sure where I can wire them to such that the halo's come on when the truck is started.

 

A fuse. But it wont be when the truck is started it will be when the key is flipped forward. Unless there is a fuse that dosent get power until the truck is running.

Like i said in my orginal post.

I ran both my power wires from each light to a fuse and just grounded the ground. Its simple

 

Oh hell that's easy.... Simply tap into ANY unused relay socket that shows hot with ignition using a simple, $10 meter or even a $5 light tester (with wire probes) for that matter.

That's how I wired my e-fan, only exception is I have a temp probe that will cut the fan off/on at certain radiator temps.

If you need a pic of what socket on an '04, I can snap a pic of where I ran the red fan (+) wire...

 

A pic would be great. I've got a meter. Should I be able to run juice to both sets of halos from the same circuit?

I understand it will likely be when the key is turned, not just when the engine is actually running.

 

Here, the top wire that's in the open relay socket...
