Installed LED's in my car...but even when "off" they stay dimly lit.

[BP-Revo]

Long story short, I had to replace a few bulbs in my G35 and in the process I replaced the majority of the running lights and interior convenience lights with white LEDs to get rid of the yellowish looking light.

Anyway, everything went smoothly except my map lights. I have them on the "auto" mode where they turn on when you open the doors (or unlock the car/turn off the engine). However, when they are "off" (door shut, engine on), they are still very dimly lit (just enough for me to notice they are producing light).

If I turn off the auto mode (so its not controlled by doors) the bulbs shut off 100%.

I've come to the conclusion that it's an issue with the car allowing current through despite being "off." (Apparently other owners have the same thing.)

So my question is, is there a way I can wire in a resistor or something that will create enough load to drop the voltage so that the LED stays off when it should be "off" but have little effect when it's on?
