This bracket is designed to add one surface mount Feniex T3 to the project of your choice. I didn’t want to heavily modify my motorcycle’s rear fender, so this attaches with 4 small flush-mounted bolts. I suggest printing this in PETG or PLA and using silicone or gasket maker to fully seal the light. I chose the Feniex T3 based off its low price (~$30 USD), reliability, small form factor, and multiple flash patterns. Just be sure to get one in red if using as a tail light!
