This came in a bundle of accessories I bought from a friend who crashed his P3. I have no need for it and am trying to defray my costs.
This clips onto the top of the P3 and provides more light for visibility, day or night. There are 4 LEDs on each leg, which clips/unclips easily to the P3 landing gear. Two legs have white LEDs and two legs have red LEDs.
Note: the brightness of the white LEDs made capture by my iPhone camera impossible. See the 4 LEDs in each reflection.
Two modes: steady and flashing.
Recharges via USB.
Clips on securely, yet easy snap on and easy to remove.
$20 plus shipping. (B&H sells these for $40.)
