Hi All, I just installed blue LED brake lights on my Mustang. I noticed as soon as I plugged them in, the LEDs lit at a low level. If you actually press the brake pedal, the light intensity increases dramatically, but there always seems to be a small current to the bulbs. Is this normal??? I don't want a battery drain, but I'm thinking that a barely lit LED bulb probably draws no more than the blinking alarm light. Any insight would be greatly appreciated.

Just as a matter of note blue lights on a personal vehicle are illegal.

The brake lights are controlled by the smart junction box (SJB). A small leakage current of a few hundred microamps flows out of it even when the brake lights are off. This current is far too weak for an incandescent bulb to give off any light, but LEDs are efficient enough to give off a faint glow from it. A simple solution is to mount a resistor in parallel with the LEDs to shunt the current around them. You will probably need resistors anyways as your turn signals will flash at an abnormal rate since the normal incandescent load isn’t present with the LEDs. That is, unless you like a fast blink rate.

Thanks, I actually misspoke, they are not brake light bulbs but the little bulbs that illuminate when you put your car in reverse. Given the number of cars I see driving around with full tint, no front plates, and other violations, I think I will take my chances on the backup lights and keep the regular bulbs in the glove box on that off chance I get flagged. :shiny:
