Dome Lights - Question on LED's..

Blue/White LEDs are very sensitive. Even in the off position, there's still a tiny bit of current flowing through the socket (probably a solid state switch from the BCM). Regular

Blue/White LEDs are very sensitive. Even in the off position, there's still a tiny bit of current flowing through the socket (probably a solid state switch from the BCM). Regular bulbs have higher resistance, so it won't light up at all.

Try rigging up a blue/white LED. Fully connect one lead, and use your fingers to "connect" the leads on the other. It'll glow dimly.

It shouldn't drain the battery.

Mines on both sides are glow very dimly. I want it 100% off when the doors are closed.

what do u mean by "Fully connect one lead, and use your fingers to "connect" the leads on the other."?

Oh just an experiment with blue/white LEDs and a battery.

The only solution I can think of to keep the LEDs "off" is to add another resistor, but it will also limit the current to the LEDs when lit sacrificing brightness a tiny bit.

I put an order in with Diode Dynamics and got a pair of red and blue panel lights. One of the red panels has a diode that stays on brightly when it should be off, and by brightly, i mean i can see it very clearly through the light panel when it should be off and the other panels are all very dim when off compared to this. I emailed them about it and they are no help. If you want my advice, its stay away from Diode Dynamics...
