incandescent bulb works correctly LED does not

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.

    LEDs do not light up without power. Either your DC lighting switch is leaking....or something screwy about your DC lighting wiring system.....
  • 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!
  • 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.
