STROBON Lights are the most powerful navigation lights on the model market for years.
It allows 2 different working modes
All you need a piece of wire or a tweezer to change the pattern. Connect two small pads of the Strobon v2 board while it's working (it will not change the pattern when it's OFF) It will stop working when you connect these pins and jump to next pattern when you release the connection.
