Since we had a thread on incandescent bulbs and LED.My problem is that the incandescent bulb works correctly, switches on and off just like it is suppose to. The LED is on no matter what position the switch is in, on or off the LED stays lit.

What series incandescent are you replacing?What LED lamp is going in?Look in socket to see how many pins in base. (small solder dimples)Sounds like the incorrect lamp.

We have a night light with the same problem. I think it is something to do with the internal circuitry of the led but that's more than I know.I like the `leakage' idea. Maybe our night light switch does not completely break the circuit or the wiring is reversed do the switch breaks the ground rather than the power. Now I know even less!

Either your DC lighting switch is leaking....or something screwy about your DC lighting wiring system.....

Sounds like what a motion detector does. They rely on a cold incandescent to "leak" a milliamp or two just to power the electronics. Not enough to light a filament but sometimes enough for LED.

Looks like Nikola Tesla is alive and well.

Those use a tiny rechargable battery or a super capacitor. The led takes so little power it can run for a while on a very small reserve.

That's worth investigating, if you care about your battery.

Do you have a battery disconnect switch?
Ever put an ammeter on your battery lines?
Could they be phosphorescent?

Clarification, this is in our stick and brick house :)

I think we lost the OP, this will remain an unsolved mystery.

If it does, you'd better hurry up and patent it. Perpetual motion or lighting with no remote power is a fantasy.

As you can see from the above comments there are many things that can go wrong.

More information is needed to sort through the possibilities.

If your switch is illuminated it can probably leak enough current to light the LED.
