    I have two led lights running via a 12v system driver. The lights flicker and I'm told that ghost or induced voltage is to blame. I need to know what type of diode or resistor to fit to the led or driver cable to stop this problem please. No other cable are nearby.

    Hello,

    Do you have more details (like a datasheet) of the driver and the used leds?
    That way we can give a more detailed answer to your problem.

    Or a dirty power supply. More information would be nice.

    The driver is from Hafele (ref 83374900) 12v/15w, input voltage 100-240v. It has a socket for the power lead and various other sockets for the lights, but I am using 2 only. The lights are 2x 12v/1.5w. The problem from what I understand (as I have little knowledge of these things) is due to the way the house electrician has wired the room. It is a new house and several neighbours have the same problem. The cabinet lights are switched with the bathroom lights coming on.

    Two lights 1.5 watt each. An electrician said that a diode or resistor needs to be attached to the cable, but not having electrical knowledge I just need to know what to purchase to deal with the flickering.

    Hello,

    Do you have the specifications of the leds?
    A datasheet or a link to the datasheet would be great.

    The LEDs are from Hafele too ref 83373200. There isn't much specification shown. There are 19 diodes on each light 125mA, cool white 5000K.

    Yes, they work, but flicker/flash. Due to induced voltage. I need to find something to attach to the cables to dissipate this ghost voltage.

    Hello,

    Can you post a drawing on how you have connected the driver and leds.
    Also mention the lenght of the cables.

    Here is how to attach an image to the post:

    Egad !! U guys are having these sorts low life problems. heee hee hee!

    And I thought I or we are the ones dealing with these kinda electrical issues with low newly wired houses.

    U switch a light on from ur living room and the next floor toilet or living room light comes on. :D
