I'm installing aftermarket gauges on my dash. I installed an LED for the E brake indicator. I removed the old light socket and spliced the red wire of the LED to the blue wire of the old indicator socket. I spliced the black wire of the LED to the black wire of the old socket. With the E brake on, the LED is bright. When I release the E brake the LED gets a little dim but remains on. I'm not sure what is going on. Any thoughts? Thanks
