This bracket is designed to add one surface mount Feniex T3 to a motorcycle license plate. One of my motorcycles was rather limited in space for mounting a light, so this bracket attaches direct to the license plate. I suggest printing this in PETG or ABS and using silicone or gasket maker to fully seal the light. That said, I’ve printed a few of these in PLA, and they’ve held up fine. As different states have slightly different sized plates, you may need to file your plate a tidge to get it to fit. 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!
