The Blue Lights for X4 H107C and H107D Quadcopters is a set of four blue LEDs that mount on the propeller posts of the X4 H107C and X4 H107D palm-sized RC quadcopters. They are designed to help make the aircraft visible at night and can also act as an alarm, flashing in the event of a low battery. They can be used to replace the original LEDs the X4 came with or if you want to mix multiple colors to, for example, help you keep track of the aircraft's orientation at night.
To install these LEDs the X4 body shell will have to be opened and the cables will need to be soldered in place.
