These are Tail Lights, strips of programmable LEDs to light up your horse's tail for higher visibility. PLUS FLAIR. You know what I do when I wanna show off my ass? Well first I have to coax him out of the barn with an apple! Get it? I hope you don't, I hope you just think I'm stupid.
Hit the jump for a couple more pictures and a video in case this concept is blowing your ridiculous little mind, then just mount lasers to the back of your saddle like a normal person.
Thanks to Wend, who agree they should make these for cats too so they can't sneak up on you in the middle of the night.
