21+ Tahoe LED Tail Lights

Tenscourts said:

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.

Do you happen to have pictures at night of your bulb setup?

Makes sense.

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?

Interesting that they are using 100 Watt while many folks have used 50 Watt on each light. I wonder if they feel that the extra resistance gives more reliable results?

The way I understand it the wattage is the amount of heat the resistor can handle before it begins to fail and in the case of our turn signals start hyperflashing. Lasfit offers a bulb that has a built in resistor but they warn if it's left on too long it will over heat and begin to hyperflash. Their resolution is to turn it off and let it cool. If I'm understanding correctly these 100 watt resistors allow for more heat load lowering the chance our bulbs will hyperflash or cause errors. Like I said earlier I measured one of these at 232 degrees and the longer you sit in reverse or hold your foot on the brake the hotter these things will get. I could be way off but I think I'm right. Additionally on the gen5diy site they sell these resistors as an upgrade "for those that are experiencing an issue with your tail lights hyper flashing after some time."

That makes good sense. Thanks for the explanation!

I'm going to go ahead and give y'all the full install video. I'm not sure what the delay is on getting the product on the site. Hopefully its out soon so you are able to order.


No guarantees but I have reached out to Diode Dynamics to see if they would offer some discount if you purchased the same set of bulbs I used.

Absolutely phenomenal work.

Take my money please. You deserve it for the work you put into this.

Here is the response I got from Diode Dynamics. Honestly I think the cost of the bulbs gets you free shipping anyway but they do say they have a sale coming up and provided a free shipping code...

"Thank you for reaching out and sending that video! Unfortunately, due to our MRP policy with our authorized Diode Dynamics dealers. We're unable to authorize discount codes outside sale periods. However, we do offer an exclusive code for free US shipping on any new or future orders using the code below.

Coupon Code: FSX72C4HS

You can share this with the forum as well. We are also going to be having a sale for Memorial Day."

I reached out to Gen5DIY for an update and was told the guy is out sick but they would have it listed by early next week.

Still waiting on the listing to be posted on the site for the harnesses but I just installed this Canvasback Cargo Liner if anyone is interested in checking it out.
