Rear Bike Light for Night Riding Cycling, 2pcs Red LED Bicycle Tail Light with 6 Spare Batteries, Mini Back Safety Bike Lights for Skateboard Kids Scooter MTB Rack, IPX5 Waterproof Taillight

This is my second buy of these lights. Very bright and efficient lighting. Simple application . Light weight and the price is unbeatable

If they don’t turn on.Open light , take out batteries and there’s a little piece of paper in between the batteries so the device can’t be turned on until you remove that piece of paper… Ran tonight very bright. Can’t complain. One bit built strong.. seems like they will last a long time

Not one, but two rear bike lights plus extra batteries for less than $6 Prime shipped, definitely a great value! Super easy to mount. Not the brightest light, but totally sufficient! Would recommend!

Great little light to be seen with, strobe, or solid, very simple to mount just about anywhere!

Bought as a two pack and neither one works. Strangely enough they came with six CR2032 button batteries but these things don't seem to have any way to replace the batteries. They are sealed units. Completely disposable. I would be very disappointed but I know the SIX batteries that cam with it are worth about 4X what I paid for these lights. Really strange.

two devices and many batteries. works exactly as described

There's rubber straps on BOTH sides of the device, making it too long. The longer strap doesn't have enough slots to pull the light tight onto your bar. Gonna try velcro for a tighter fit that will last. Usually these things will fall off once you ride over bumps. Other than that it's bright, easy to install the batteries & getting those spare batteries makes this a good deal. (6-pack of 2032's cost about $14 these days).

Hubby's bike needed some lights on it since that did not come with bike. For the cost these lights are perfect. @ pack is worth the price to make sure he can be seen. Fast shipping & packaging oif items was spot on, Thanks again
