Mount led on top of boom with the bright spot of led hitting the blade 1/4 inch from the tip.

Easy way to mount bulb is to use a spot of hot glue on the top of the boom to nest the led in ,
also 2 small zip ties or string  to safely hold the LED in place.
Power the Led from your lipo battery by tapping into the wires running to the Electronic Speed Control. You can also use a 12 volt battery. The led is set for 12 volts but will run on 
lower voltage with diminished results.

The cluster led should be mounted so that it shines on 3/4 of the blade. It can be mounted on a tail boom guide ring as see in the pics. or it can be mounted on the fin.
It should be powered by the same battery that runs your glow wire. The cluster led is also set for 12 volts but will run on lower voltage with diminished results.
