I purchased the Firehouse Cree strobes - 2 white and 2 red. I intended to put the 2 white on mounts on the front of the drone and the two red on mounts on the back of the drone. I'm doing this to improve the drone's visibility for my eyes. Now that I have them I began to wonder about which color to place in which position. Are there any restrictions on what colors go in front vs go in back? Thanks.
