Did you bake them to loosen the glue for separation?
I've done this before on Fords. But the complex curves had me worried about breakage. I want to separate my current heads to matte black the interiors pieces. And probably install a brighter LED strip like you have

Yes. I baked it at 250-275 degrees F which was a little too hot. This was a damaged headlight I bought for $50. It’s a 2015-2017 model. I believe it’s from a 2017 Tahoe. I’m using it for R&D to determine if the led strip can be made to have the same brightness as the 2018+ headlights.
Since I have a Yukon, I need someone to take some voltage measurements at their Tahoe/Suburban headlight connector under certain conditions.

Hello, new to the forum, researching the DRL head lamp vs. LED strip for my '17 Suburban. At this point I don't think Chevy will abe providing a solution. I'm planning to install HIDs in the coming months, and I definitely don't want to use the HIDs at full power for DRL(HIDs are not dimmable as I understand it). Like many here, I really want to use the LED strip for DRL. I've seen a few solutions posted here, but I don't want to do any cutting/splicing on the harness. I'm thinking about building an electronics module that will power the LED strip and turn off headlamps during daylight operation (ie DRL mode) and automatically switch back to original headlamp/LED drive signals when headlights are fully ON, whether from Auto or manual turn on. I'm hoping a plug&play solution is possible. If I had such a module, from what I understand, I should be able to then install a standard HID aftermarket kit installation and have the system give me DRL via LED and HID for low beam headlights. I will post progress here on what I find out, unless there is a better thread on the forum for this.
Does anyone know what the PWM frequency used for the headlamps is? I will verify at some point, but it would help with some early designing if this is known.
Thanks.

Thanks.
the DRL runs at a lower voltage 9volts if it's on the low headlights or high beams...
if it's on it's own reflector or signal bulb then it will run at the full 12 volts..
on the LED you will need to use diodes to prevent feedback of power over the DRL and headlight circuit... other wise when it's DRL mode it will burn out the DRL fuse on the spot might cause damage
just don't make a full bridge rectifier LOL
the LED module should have it's own driver that runs off of 12volts this can be confirmed with a mut
also running LEDS without a load will cause it to display a DRL Bulb out message....
if you can run the DRL circuit to the Fog lamps... would be the best bet
as the DRL are typically off when the fog lamps are able to turn on

Thanks for the info and tips. Do you have an idea of how much load the DRL circuit needs in order to avoid a bulb failure detect?
25 watts minimum if they use the 3157 bulbs might need a smoothing cap or driver to prevent flickering/strobing
First check the fuse size before hand... on the DRL (25 watts =2 amps)
Ok, thanks for the input.
Been spending a good amount of time studying the lighting schematics for my truck; little bit of progress on ideas for the electronics, but I need more information on how the DRL PWM operates in terms of pulse frequency to help with electronics design; looks like I will need to get an engineer buddy to help get the measurements from the DRL and LED operation. Not sure when that will happen given holidays and work schedule...Will post back results when I get them.
