2020 Silverado hd wigwag?

[carguy411]

Has anyone put in headlight wig wags On the new 2020 Silverado LT 2500 HD. We just ordered ours to replace the older utility . If anyone has done it which flasher and was there any issue. These new cars with everything running through canbus system don’t know if it would be an issue . As an alternative I was thinking to put white haw in the upper turn signal housing at a slow single flash alternating pattern to simulated it. I know it’s not as good as actual wigwag but
Thanks in advance

why not just avoid it completely and use a pair of spot or flood lights with a headlight flasher mounted on a grille guard?

Thought of that but might mount a 4 head stick to it
That is if one of the major manufacturers releases a push bar for it. So far no one has them out yet

I seen that. I was thinking more like setina and proguard. They have a flat bar across the middle which makes mounting to it easier

Haven’t got the truck yet but I think the ideas i had won’t really work. I guess I’m going with a flasher module prob the whelen UHF2150A
I’m just still wondering will this screw anything up in canbus system ?
Anyone see any issue with that flasher on here. Seems like a straight forward thing but these new cars are temperamental

According to the 2020 schematics, each high beam wire is Yellow at the back of the headlight. A normal two output halogen flasher will work fine.

I used a SoundOff ISO flasher on my 2018 2500HD and it worked perfectly. I even flashed each module of a dual Pioneer Slimline at the same time. Looks great

Thanks guys. It’s strange for poop and laughter I emailed whelen about using the ulf. Flasher and they said they don’t recommend flashing the 2020 high beams
So now I’m confused lol

Would it be cheaper to just have someone wiggle the highbeam switch instead?? These funky lights, have you checked with Chevy to see if there's an upfitter PDF or something on this vehicle to give you a lil help?

That is a good idea. I could have one of the new guys do it

I’m not sure if there is a up fit guide for the 2500 I’ll have to look. I don’t know why whelen said that they don’t recommend it. I guess they worried about bcm

All the vehicle schematics are available at gmupfitter.com

Whelen probably said that because they haven't confirmed it will work yet. Each highbeam is driven by a separate relay, much like any other vehicle for the past 30 years.

Thanks what I was thinking. I think If I use. The ulf2150a. Positive switching It should be fine wiring behind headlights ,it’s after the relay and the bcm

Attached above is a 2019 1500, should be similar operating systems. There are many trims on these, some have halogen and upper trims have LED. This a halogen system.

I just saw that one I was thinking same thing unless something changed with the 2020 2500 but I doubt it. I guess I could try it.
What’s the worse that can happen lol
