Disabling Daytime Running Lights (DRL)

[flyin99]

Check right next to H. Here is the list of both plugs for each headlight, with wire colors.

i checked on the bcm side of the connector and failed to see the DRL specific yellow wire. my thinking would be that this slot would be reserved for the sierra DRL seeing as they are separate drivers from the lowbeam bulb.

_{I have a Sierra SLE which doesn't have the LED DRL's. The Sierra uses high and low beam in the same bulb. So, I'm wondering if the BCM is different than the Silverado???}

Same BCM. Different flash maybe

Here's a pic of my SLT BCM.

Does anyone know if you install an aftermarket HID kit, if the DRL feature would be bad for them...the constant on, off, on, off if you turn them off immediately after they turn on after being shifted into gear? this is the only thing that is holding me back from getting a DDM kit.

I wonder how difficult it would be to disassemble the headlight switch and remove the spring feature that prevents leaving it in the OFF position?

Was pretty easy to do on my 2015.

i wanna disable the auto lights to..haha

Did you ever figure out how to disable the auto lights? I have an SLT Sierra, so I'm fine with running lights or leds always on, but I have an hid kit in there and the auto feature is way too sensitive. Even when its not very dark out and I unlock my truck the headlights come on, then I have to wait for them to go off, then start the truck and they're on again. Going to kill the hids.

 

Is there at least a way I can disable the headlights from coming on when I unlock the truck when its 'dark' enough out to trigger the auto function

The unlock lighting should be able to be disabled under the vehicle configuration menu under "approach lighting".

no i havent tried that yet..i wanna hook a resistor up to the light sensor under the dash and trick it. worked on the older trucks..

So, no one except for Chris White can disable the DRLs/automatic lights? it is total b.s. that Chevrolet service departments will not disable them via the BCM. The federal laws were changed in 1990 so that GM could sell vehicles in the U.S. with DRLs and automatic light features. There are no laws within U.S. borders stating we are required to have DRLs or automatic lights.

It's not that they won't, more likely they can't. The diagnostic tools dealers have aren't magical. If GM doesn't want it messed with it won't be changeable.

Boooo down with GM promoting safety. I wish half the morons driving in this snow had automatic lights.

[Rewillia]

Am I missing something here. I just switch my light switch position all the way to the left (off position setting) and all lights are off.

[04GMshorty]

yea but like stated above its spring loaded, so once its put into drive the drls come on no matter what..

 

interesting point about removing the spring in the switch..still wouldn't turn off the drl though..thats gonna take some wire harness or bcm work..

 

im getting resistors this week to do the auto headlights but still have to figure out the drls..
