I found some 12v LED brake light bulb replacements and mounted them to the rear boom, but I couldn't see it very well and then during a job it broke off. So I decided to up the game. Ingredients- 2x old-skool flashlights from the dollar store, with good reflectors. 2x 12v LED brakelight bulb replacements. Like These Hot glue and wire and zipties of course. Take out the reflectors. Unsolder the base from the LEDS so they have a flat bottom, and solder the power wires on, so they exit down the center. Hot glue them in the flat part of the reflector. I used the screw cap that would hold the flashlight bulb in place and then made a hot glue wall that forms to the 25mm boom. Then zip tie it all on the boom. I had to saw the edges of the reflectors where they meet, and put some hot glue to hold them together, but it ended up very solid. They look like bug eyes and even in bright sun I can always see them. I was pretty amazed. The viewing angle is very large too. Even at 90 degrees I could see them well. At night they look like afterburners. Hope you find this helpful!
