LED BRake Light Problem

I have a 99 and have just put in a set of LED's for my brake lights. They work fine, and there are no blown fuses, but my "brake lamp" light is on(on the dash). Any ideas why this is happening? Again, I don't see any problems yet, other than the dash light.

Try putting a resistor in parallel with the LED (I assume the LED "bulb" has a series resistor). IIRC the 921 bulb draws about 1.2-1.4A, so you probably want a 10-20 ohm power resistor (remember that, don't use 1/4 watt resistors). You can get 8 ohm power resistors at Radio Shack. Put two in series and put that combo in parallel with the LED "bulb". Should cost a couple of bucks.

Did some troubleshooting this weekend. Found the cause of my problem. My "Brake Lamp Sensor" was bad. I had burnt a solder run on the circuit card. I resoldered it and all is well !! Now I am going to e-mail A1C performance manufacturers and let them know about the problem. Thanks for all your help guys!!
