Review on 🚲 NiteRider Sentinel 150 Lumens USB Rechargeable Bike Tail Light - Powerful Lasers, Daylight Visibility - Easy Installation for Men, Women - Road, Mountain, City Commuting, Cycling Safety Flash by Gary Duncan

My local bike shop had a rack mount that I could attach to the back of my rack, which means NiteRider has it. Looks like it's now on Revain as a separate item to order. I twisted a flat hair tie around the center of the lamp and the back of the mounting clip behind it just to be absolutely sure it wouldn't pop out if I hit any bumps. It doesn't block light. I bought an adapter (less than $5) to charge the light from an outlet next to my bike in the garage. (USB cable included.) This is the best bike lane taillight available, much better made than the other three I've tried. I like the fast flashing bike lane mode with slow flashing rear LED. The cars are moving about four feet so obviously they can see it. Based on another customer's warning that the charging port plug popped out and is leaking water, I take half a plastic patch, cut it in half lengthwise and glue it in place. via the stopper (two thin strips) every time after I charge the taillight about once a week. This should solve the problem of the cork falling out. It's a minor hassle, but worth it for the peace of mind.
