No daytime lights on 03 Yukon?

My DRLs won't come on. Does my truck not have that feature or are the bulbs out or something? Or do I need to enable them?

Also, I've always wondered what these are for... And do the tail lights come on with the DRL?

Thanks.

You can check the DRL fuse. If that is fine the bulbs are probably burnt out, nobody really ever checks them.

No your tail lights do not come on with the DRLs.

They don't come on in park. And they're mostly for safety.

Check the bulbs. Mine were fried but that didn't fix mine, the sensor on top of the dash in mine went bad installed a new one they work now.

I replaced the bulbs with those from the tails since I got new LED tails, and they work now!

Recycling parts FTW!
