In the constant struggle many of us have with our daytime running lights, I decided to pull the DRL fuses to find out what they do. Apparently.... nothing. I pulled each one and both DRL fuses and they didn't seem to effect anything. I verified that there is power running through them when the lights are on.... whether I leave them on automatic or by using the switch. But I have no idea what that power is going to.

Can anyone shine some light on what these two DRL fuses are actually for?

I'm using one of them to power my wheel well lights.
