Yep, I'm wondering if this switch mod would work for us or if they they would need to be disabled in the programming.

As a motorcycle rider DRL's have made me less noticeable now. That is a real safety issue, I'm not safely tucked in a steel cage like the average motorist.. Everyone is so used to seeing headlights o

I have the GM TechII and you can't disable the DRLs, why would you want to anyway it's one of the best safety features ever put on a vehicle.

Not sure if you're a guy or girl but I guess you're not a very patient person then if you can't wait 1 minute for the ambient light sensor circuit to shut them off for you. Personally I find it works

Try it out by holding the switch over in the off position and start up vehicle and put in drive all while holding the switch off. I'm curious.

Nope, DRL's are on no matter what, waiting on my GM dealer OBD programmer system I ordered to get here so I can see what settings we can play with lol

 

Edit: Nope, just tested it! DRl's ........ etc

DRLs are mandatory here in Canada.

 

I have a US-issued 2015 Silverado LT. I have not done anything to the factory switch. If I turn it to "OFF" then let it spring back to the AUTO position my DRL's turn off. I have done it while in Drive and know it works that way (while sitting in traffic with my foot on the brakes I can see my lights go off in the reflection in the car in front of me). They stay off until I spring the knob to the left again to re-enable auto lights or until I shut off and restart the truck (which re-enables them too).

Auto lights and DRLs are two different things.

Why would auto lights be on in the daytime??

If it was dark when you last used your truck they will be on when you start it even if it's daylight. There's a hysteresis timer and it takes a couple of minutes to switch. This is so they don't turn on and off when you hit a shadow area like an overpass.

That's the way mine was as well sk. I didn't like having to turn my lights off EVERY time I used my truck instead of just having to turn my lights on at night.

:crackup: Not sure if you're a guy or girl but I guess you're not a very patient person then if you can't wait 1 minute for the ambient light sensor circuit to shut them off for you. Personally I find it works perfect the way it is. Meet to many non GM cars at dusk or later with no lights on. Daaaaaangerousssss in my opinion. Please don't take this personally I'm just observing here and just don't understand your need to pull out this spring in the switch. Let a sleeping lion sleep. I pray to GOD you don't hit a biker this summer because he didn't see your lights.

I know that.

 

What I am telling you is that on the 2014/2015 Silverados the upper headlight (low beam) is used as the DRL during the day. If you turn the dash switch to the left it disables ALL the lights (DRL, parking lamps, and auto-headlights) and you can drive without any lights on. So it DOES disable the DRL's but it only does it until the truck is shut off and restarted. At that point the DRL circuit automatically re-energizes until you turn the switch again.

 

Again this is for a US truck. I don't know if the Canadian DOT laws work the same way.

Exactly right sk. Coby, read sk's post. This isn't only about the auto headlights it's also about the drl's. Every time I drove my truck in the daytime the lights were on full time. Nice sleeping lion quote. Here's one for you: If it ain't broke don't fix it, - Gm full time headlights are worthless except to get you to replace them more often. I'm not sure how I eeked through my first 50 years of driving without headlights in the daytime for safety. Lol

      Tire pressure for 37s

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter

      My First Project and GMC has me stumped

      By asilverblazer · Posted

      I had an alternator fail that was shorted internally in such a direct fashion in addition to the larger gauge cables that it appeared like a VERY dead battery. Granted I think the car did power up, it definitely wouldn't start.   Rodent damage to wiring?

      Towing In Loose Gravel

      By asilverblazer · Posted

      Using experience to justify bad advice is lazy and typical of someone incapable of articulating why their advice is prudent.    This immediately sets off the BS alert and the advice that followed certainly qualified.   Asking an idiot for help getting out of dumb situations because he is an expert... at getting himself into dumb situations.   Unless I've been living in an alternate universe - the first thing everyone does when getting into a sticky situation is shift to a higher gear 🤨.   Of course not, the torque multiplication, mechanical advantage and finer control typically afforded by the lower gear is far better suited for this scenario.   There ARE scenarios where a higher gear MIGHT be appropriate determined more by the drivers ability to control EXCESSIVE wheel spin versus applying torque to the ground.

      I'm not sure I agree with "extreme" low speed, high torque sentiment here with regards to the prescribed use of low range. How about...whenever it's needed?   A 2.72:1 transfer case and whatever differential gears these Silverados have (3.42's, maybe?) aren't producing "extremely" low crawl speeds. Or insanely high torque multiplication. Even with the 1st gear in these newer transmissions. But it does provide mechanical advantage and potentially better control at slower speeds. And with extra weight or towing, I think it adds mechanical sympathy for the truck as well.   Plus, traction control and the other assists generally turn off when you shift into low range. Those aren't needed here, they'll work against you if you need wheel spin. In high range you'll need to figure out how to turn off the various modes those assists provide. Depending on the vehicle, those things don't all automatically turn off or turn completely off.   While I agree that a farmer might have some great practical experience, a recommendation to "always" using one gear isn't very informed advice. If the farmer had said WHY and could explain the physics behind his prescriptive "always" I'd definitely listen. The way he's described here makes it sounds like he could either be uninformed or is telling everyone what worked for him, not necessarily that there could be a more advantageous way about things.
