Ok so I have a 02 Denali and I have been debating on replacing the stock tailights with are really dull with a set of the LED taillights. Which brand should I be looking at? Are they worth the change? Should I just get factory replacements?

Here's mine, LED taillights off eBay. I love they're look and the LEDs are stunning however I do lose my cruise anytime the lights are activated. So someone on here suggested the spyder ones bc they have load resistors built in to solve this issue, go with those.

Those look great, I'm sure you could probably add resistors.

You need to add a least one load resistor to the brake light circuit.
Any of these lights that include load resistors are only putting them on the turn signals.

I'm not sure of the "why" it works that way, but I'm guessing the cruise control grounds through the brake light circuit. (If you have read up on the way the side marker lights work, I think it would be something similar.
So we should only need to put a loading resistor on one side.
I'm not sure if it works the same way with your truck, but my '00 Yukon XL's cruse control stopped working as soon as I installed my LED tails. I have yet to install a loading resistor because it's winter here, and I don't want to work on the truck in the cold.

I ordered these for my fogs. I'll post a pic when I get the new housings next week. All bulbs will be led then!

installed these and they are excellent, not as nice as my TRS XBLED, but they are really close. REally the only difference is the cutoff of the XBLED was better but the XBLed are $200

Hey thank you. I've never done that before so I'd have to look deeper into how it's done before attempting. I noticed that it only kills the cruise when running lights are on or I use my right signal. Maybe same with yours?
