LED BRake Light Problem - Toyota Nation Forum : Toyota Car and Truck Forums

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.

Maybe i has something to to with the wattage or the voltage. Just a stupid guess by me.

They are not drawing the same current as the standard bulbs would and it thinks a bulb is burned out.

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!!

I just wrote to APC performance. Hopefully something can be done about this because I really like these.
