LED 3rd Brake Light and Cruise not compatible???

To be honest with you, im not sure. I know some cars do. I havent looked at the fuse panel on my truck yet. I've only had it a month, so I haven't had any major issues yet. I switched my 3rd light brake light to LEDs when I got the Hella Tails and 3rd brake light. I didnt have any issues with my cruise control.

Your Hella's prob. have a built-in resistor, el cheapo's like I bought did not, and I had the same problem the O.P has.

Come to think of it, I dont know that Ive actually used my cruise control since I put the lights on. My commutes to work are normally heavy traffic. Im gonna try to remember to test my CC today after I get off. Yall have me nervous now.

(I'm not well versed in LEDs at all)
Here is what I have on my truck. LED tailights/brake lights, new LED flasher, and LED third brake light.
I added the rear bulbs and flasher first, and everything still worked fine. Once I added the 3rd brake light, no more cruise.

Thanks for the response...now how do I do that?? I am not familiar with LED lighting, so I'm not sure what that means.

Basically you need to add a resistor to simulate the load of normal bulbs, thus tricking the flasher into thinking everything is okay. Buy yourself a resistor kit - ebay, Auto Lumination, V-Leds, etc. Splice one side into the high circuit of the turn signal line (or the brake line in the 3rd light) and the other side to ground. Maybe this will help: diagram from Super Lumination

Well, I just replaced my LED flasher with the regular one and add two 3ohm resistors to the front turns. I noticed the third brake is still on dim with headlights. I also took a test drive to check the cruise with no luck. Back to square one with the cruise. I really don't mind the dim brake light either. I might now put the regular third brake in and try that. Come to think of it I don't remember if the cruise worked when I bought it 'till I put the Recon on (my first mod).
