3rd Brake Light LED Kit Anyone?
I have a 09 SS so I can't comment on ALL cars. This is what happened when I installed an aftermarket 32 LED strip into my lamp housing. I didn't have much hair BEFORE this episode but after the troubleshooting required to fix it I have a lot LESS now.
If you will read your owners manual you see that to ARM the cruise control you must hit the brakes once after starting the car to allow the cruise to be turned on. This is a safety feature built into the system to verify that the brakes are working BEFORE ALLOWING the cruise to be set because the BRAKES are the primary method by which the cruise is turned off. The system uses the High Mount Brake Light to sense the brake function. It does this by sensing the current draw across the High Mount lamp. Because there is so little resistance across an LED there isn't enough current sensed to allow the cruise to turn on. This is the same condition that causes rapid flashing LED's. If you used a LED lamp from another vehicle it probably has the resistor circuitry built in. There's plenty of reference material around.

If something had been available, when I did mine, for $30, including shipping, I would have jumped on it.

As you know, LEDs require very little power, so if you put 12v to them without resistors they will burn out fairly quickly.
Our boards have resistors wired in to provide the resistance needed for long led bulb life. That provides enough resistance to allow the cruise to work properly.
My car is an 08, Mike's is an 09. Between the 2 cars we've had over 50 cruise control activations since the install of these.
Im confident these will work just fine.
Thanks everyone for your interest!
Wow... so much wrong information in this thread.
You need resistors in parallel.
my 06 ss/sc had 3rd led from modern performance and worked fine.
When I bought one for my tc the 3rd brake light would stay slightly illuminated when parking lights where on,
and it would stay dimly light for ten minutes after the car was shut off
if theirs a way to fix this i would order one!

I got Impala LED strip for under $10 at a junk yard.
Now, if you sold ones for $20-$25 that lock LEVEL inside the stock housing, I'd pay $25 for it rather that $10 and have to ghetto tape it inside.
