Gaciron Bicycle Safety Taillight 10 lumens Bike Helmet Light Wearable, USB Rechargeable LED Cycling Rear Light with Reflector for Alarm, and Super Bright IPX6 waterproof Daily Commutes

good quality light, like the fact it has built in reflectors so removes the need to have a separate rear reflector. Decent level of brightness, easy to use and good quality fittings.

Just perfect for alertness and bright too

Very bright flashing light for day light use attached to the back of my helmet

Only used it once, it fell off the bracket on a bumpy road on the first ride. Got home with the bracket but with no light.
