They are absolutely beautiful under the 1:1 transoms on boats. They are real sexy at night.
Cool upgrade for a RC but I would buy the 120 degree LED's to get the most bright ones you can.
I use these for my gauge cluster in my car and they are the brightest I have found. Regular LED's might not be very bright under water.
Go here, they are the 3rd one down from the top

You can get them in all sorts of colors. I have Blue on my dash(one of the hardest colors to get to be bright enough to see your gauges at night) They work great. Fast shipping too. I think I willdo this mod once I get my Boat up and running just for fun.
