2006 Tahoe. CC was working. I installed LED's then noticed no CC. I read that LEDs pull lower voltage and the computer thinks a brake light is out killing the CC. I'll put back the original bulbs. Does that mean LEDs are not an option or is there a workaround?

OK, so two part plan, please let me know if this will be a problem. I presently have 2 LED 3157 brake lights (white color). I am told LED red shows better through the red brake lens. I can put the red 3157 LEDs for the brakes, then put amber LEDs for the turns in the rear. That makes 4 LED lights in the rear. I purchased this kit where I can put a 50w resistor on each of the 4 LEDs. Any problems doing this? I plan to self-tap/mount the resistor somewhere on the metal body of the truck away from plastic and wiring as much as possible.

I would wire resistors for only the brake lights so you still have cruise control.

For turn signals I would get the novita led flasher. That way you dont have 2 sets of hot resistors behind your light housing.

Yes with personal experience I can confirm red led bulbs are actually brighter than white with red lenses, so get some red bulbs. Amber I'm not sure but I would assume it would be the same.

What do you have for front lights? Leds?

Oh yeah, I forgot I did that on my 02. For my 08 Silvy it was 2 sets of resistors since that flasher is built into the bcm.

Yea I hear the 07+ are a pain if you want leds for anything. Outside and inside lights. But still ways to do it

Depending on your electrical system, you may need a different relay than this one. I have an ‘05 Tahoe, and mine needed a different LED-compatible relay than earlier models.

If you do a search online, some SSR owners were having the same issue, and they detailed that the LM486 worked for them. This is what I have installed on my truck, and it works for me.

Good to know. I've only used old fashion resistors.

You have a picture to where that installs? I'm running those resistors for my front signals (switchbacks) and wouldn't mind pulling the resistors in place of a relay

So I ended up only using the 3157 R (Red) LEDs for my rear brakes. I left the turn and reverse lights incandescent. I installed a 6ohm 50w resistor on each brake light, then used a #6 self tapping screw to mount the resistor down into the chassis away from the lamps. Up front I have 2 LEDs only for running lights. Cruise control works again. I'm pretty happy with this unless someone has an upgrade for the headlight incandescent bulbs.

Hid or led in stock housing. Your preference. Stick with 5000k (white) or 6000k (white/blue) color temp.

I have read that we can install 4 leds but risk hyperflashing with more bulbs installed even with the new flasher relay. I installed 4 leds up front for corner and main signal flashers, the relay and spyder led tails. I am assuming that the spyder tails have resistors from their factory because my signals flash correctly. Anyone else with this experience? On a side note....I have not tested CC yet! Sorry to hijack thread. Just seems a few knowledgeable people are commenting here on the topic!

I've read reviews that the led flasher is only designed for one pair of led bulbs and if more are added the led flasher cant keep up with it and they still hyperflash

This is the reason why I didn't get the led flasher. Because I have all lights switched to leds

But I've read reviews of people using it with success too so idk if its year or bcm or what

Kinda late to the party here, but I installed LED tail lights from CARID, installed an LED relay from Superbright LEDs and have no issues. CC still works fine.

I am so glad that it worked! I read multiple threads on the topic and I followed the steps from one post. Installed the spyder tails and checked with oem flasher and everything worked. installed flasher and front corner 194's and it worked. Then installed the 3157 front flashers and it still worked! I have led drl's but I have not seen them turn on yet as I have not driven the truck since install but I will update on CC once I have tried it!

Thanks, I am behind the times. I didn't think there was an LED headlight out there, and I thought HIDs only work with HID housings. Good to know. I'll definitely look into them.
Well it's usually a no no to put hids in stock housings. But ours have a diffuser lens (older style lights) so it dispurses the light much better than crystal clear lenses (aftermarket or newer vehicle lights) . So hids do fine in our lights.

Stock lights with diffuser lens

Aftermarket with crystal clear lens, try not to put hids or leds in these.
