These weigh nothing, are super bright, and the drain is in the .001 amp (per light) range. I intend on getting several more (I had 1 that I found) and constructing a harness style setup that sports 4 lights (2 on each side).
FYI the 1k 1/2 watt resistor will easily power several of these
I'd love to adapt the centrifugal switch idea into main rotor lights, use a Li 3.7volt 'button' battery...
e-bay has these: http://www.ebay.com/sch/i.html?_nkw=valve+stem+lights
That sounds interesting. If I understand, the leds are powered directly by the battery with the resistor between the battery and the led?
