    I will probably not understand the answer, but here goes.

    I am wiring a LED light to my motorcycle to alert me when my radar detector goes off. Using the headphone output to trigger a solid state relay (Magnecraft 70S2-04-B-03-V) to control the LED.

    I am getting the 12V from a relay wired direct to the battery.

    When I put it all together on the bench and tested it using my car batery charger as a power source it worked perfect. The LED flashed in sync with the sounds the radar dectector would make if the earphone jack was not being used.

    When I wired it to the bike and activated the radar dectector the LED came on and stayed on as if the relay was not resetting.

    Any ideas for an electronics idiot?

    Thanks

    If it is a TRIAC style output relay, it will never turn off with pure DC. Your battery charger may have an un-smoothed output which could well allow the TRIAC to drop out.

    Why do you have an illegal radar detector?
    Why do you risk killing innocent people and yourself when you break the speed limit?
    Why does your country still use old fashioned radar instead of new laser technology?
