Review on 🚲 Tek Bike Light Lumina Adapter Mount: Optimal Compatibility with NiteRider Lumina, Mako Series, and Garmin Computer Mount – A Must-Have Accessory by William Burnett

My NR Lunina 350 fits perfectly with this adapter - Dovetail fits well - Solid and stable fit. The spot is too thin for the light to pop after the jump from curbs, over potholes, etc. could not slip off. Too much vibration and your headlight will fall and hit the ground. Easily solved with a (green) rubber strap and 5 months of daily driving with no problems with NR Lumina falling off the adapter. A "serrated washer locknut" and button head machine screw were used to secure the adapter to the aluminum bracket after welding. to the top of my barrel. Not sure about fitUP with GoPro.
