OK finally getting around to doing the light cycles, bought the hallmark ones off ebay for around US$15 each (plus shipping which sadly doubles the price)..
Blue cycle arrived still waiting on yellow (clu) to arrive.. Can pull the top off pretty easy to access switch which I will just remove and solder the wires so it is always on with the pin once I remove the batteries and solder in wires to 5v power source in pin..
Will post pic up once installed... but seen plenty online and they look good for a $30 mod (per cycle) plus some wire...
