21+ Tahoe LED Tail Lights

[Tenscourts]

I'm happy to report that my plug and play harnesses seem to be functioning as expected. No warnings or errors and all the bulbs have been replaced with LEDs. Hopefully tomorrow I can provide you all with some ordering info if you are interested.

Good news!

Please keep us posted. What bulbs did you end up going with?

I used diode dynamics bulbs. A little pricey but I have them in my 16 Silverado tail lights as well.

So this harness just inter-connects under the rear quarter panel and provides the resistors for all three bulbs?

Which harnesses did you use?

Correct.

These are new harnesses that will be available soon at Gen5diy.com. I've provided them with an install video and they will have them listed for sale soon. I'm not aware anyone else offers these. I've seen people tap resistors in behind the tail lamps but I've measured temperatures on these resistors at 230 degrees fahrenheit plus so I really don't see how that's a safe way to do this and there isn't a lot of room behind the fixtures anyway. I also hate tapping wires and this solution is plug and play.

Yes, correct. No one else offers anything like this. Every other LED manufacturer that offers you the resistors tells you to plug them in in line with your bulbs or put a harness behind the lamp.

Truly grateful you've taken the time to develop test something like this that will be plug and play underneath the vehicle for the heat won't damage the headlamp.

Especially if we're able to run all three bulbs on the same harness without any dash errors.

Jesus that's hot.

My unknown brand aftermarket LED license plate light housings have optional tiny plug-in resistors. I just removed the resistors as there's no warning or error otherwise. However they've been there for about a year and a half with no issues.

Is that in a T1XX (2021+) ?

Previous generation.

Sorry guys. I'm waiting on the website to get the listing up. I can say I went on a road trip Wednesday from Eastern North Carolina to Busch Gardens in Williamsburg VA and I didn't get a single error, warning, or issue regarding the lights. It's about 3 hours one way.

Great news
I'm excited

Same here, can’t wait to try out. Seems like the best option for installing LED lights.

While we all wait, do you have any pics of the installed harness by any chance you can share?

The install video I made was three parts. Here is the first part before I merged the three and sent it in.

This is great! Thanks for sharing!

Those are 3 enormous resistors! Wouldn't you need 4, marker, brake, turn signal, reverse? Or or all 3 resistors shown here solely for the reverse light circuit?

Marker is already LED.

Turn, brake, and reverse are not.

 

[BlaineBug]

Marker is already LED.

Turn, brake, and reverse are not.

So essentially it's the same configuration as the 2020 Tahoe with the addition of an amber turn signal.

 

[Tenscourts]

Brake and Turn Signals are separate circuits on each side. The reverse lights are a single circuit which is why you only need three resistors on one side and two on the other. It doesn't matter which harness goes on which side. Sorry for the delay but I'm still waiting for them to get the listing up on the site.
