I find night flying fun, with all kinds of lights attached, but then I don't try to video at night.
I have little lights, in all colors, that stick to small metal discs glued to my P2. They use a watch battery and they are very lightweight, yet VERY bright. I rig mine like large size crafts, with navigation lights and white beacons. Then a LOT of other really cool lighting, with a UFO look!
I found some long foam rods, with RGB LEDS inside and there are many color choices, just by pushing the switch. They look great attached, with zip ties, to the landing gears and even the arms - one on each side.
Then, I have a infrared controlled light strip that encompasses my P2. The colors morph, strobe, fade in and out, steady, etc. The number of possible color combinations is very numerous and amazing! Look on eBay for this.
