[QUOTE="Robert M, post: 16027753, member: 9628"] I had the same problem with my 2008 GT500, except it was the reverse lights. The solution was not to dig into finding a short in your electrical system, because it is the body lighting module (BLM) that is lighting that low resistance LED. The resistance in a incandescent bulb is greater and it takes more current flow to light it, there is always voltage at those bulbs from the BLM, but not enough to light the incandescent filament. The solution is to buy a CANBUS LED bulb for that location. The CANBUS LED's have a resistor built into their circuitry and provide the amount of resistance (similar to the OE bulb) and do not allow the LED to light under normal "key-off" conditions, just like the original incandescent bulb. I have CANBUS LED's in several locations on my 2008 where the non-CANBUS LED's would stay dimly light. I used Super Bright brand CANBUS LED's and have had no issues since, that was 4+ years ago and my car is completely LED'ed except for the HID headlights. SuperBrightleds.com is the website I think, look for the CANBUS LED's under your specific application, they work. Also remember, use the correct color LED, RED behind a Red lens etc., otherwise the LED light gets a washed out look to it from the outward appearance. R [/QUOTE]
