    Circuit Design help for Garden lights

    I am (hopefully) creating some walkway lights for my garden. Probably six 12 Volt downlighters .

The problem I face...

    12 volt LED flashing when off.

    LED lamp flashes every 10-15 seconds when switched off. The lamp is in a bathroom in circuit with a timed overrun extract fan. I understand that the cause can be induced voltage, or bleed off from the electronic switch in the fan timer. Is there a simple solution to this?
