disabling daytime run lights

dynoray · May 2, 2015

i just bought a 2015 2500 and im wondering how to disable the DRLs. i did it on my 2012 by taking out 2 fuses. i dont see those fuses there. anyone do this on the new ones yet?

I wanted to do the same thing, but alas, they did away with the two fuse gig I had done in the past also. But, I have conditioned myself to reach over and turn the knob to the left and disable the DRL's when I start the pickup. Message comes up on the DIC saying daytime running lights disabled and you dismiss that message. I park the pickup in the garage and can tell that they are turned off. Also, when the wife is driving and coming to pick me up from my semi truck, I can tell they are off if she remembered to do the left turn thing when she started it up or any time enroute. Still seeking a more permanent solution, but this one has me somewhat satisfied.

Some wonder why anyone would even want to disable the DRL's. But those folks never go hunting or dealing with livestock on a farm or ranch.

yeah,that kinda stinks. I just don't like em on except for bad weather etc. being a mechanic for many years I get tired of changing burned out bulbs and melted plugs and wiring in the headlamp assemblies. that's why I always disabled them on my cars. maybe at some point someone will chime in with a fix for us. thanks

Start the truck, turn the headlight knob a click to the left to turn off DRL's, push and hold traction control to turn off traction control and stabilitrac and good to go.

I opened up the switch, removed the return spring, put switch back together and all set. Switch stays in the off position now.

That's an interesting idea. Thanks! I will have to take a look at that.

Can't you just pull all fuses found on the fuse box? That usually does the trick.

Cowpie · May 7, 2015

No fuses on 2015. They figured out we were pulling them and hard wired DRL's.

Some vehicles the DRLs are the hi-beams. Of all the vehicles that have their DRLs as headlights, about 95% use their hi-beams. Would love to switch my DRLs from lo to hi.
