I went to a store called Party City and bought these cool flashing led lights that go onto a bike's wheel. They only cost me $1 and come in a pack of two, so I decided to buy them and strip it apart to make led lights for my helicopter. They have 3 led's and a flashing board that I rewired and strung up onto my helicopter. For wire, I stripped it out of a telephone cable to wire up the led's. Hooked up a resistor, plugged it into the receiver and I was done.

Here is a small video and some pictures.

I will create a better detailed photo log on my second set of lights. You could say it cost me .50 cents each set .
