Bicycle Cycling Laser Tail Light Laser & LED Mountain Bike Safety warning Flashing Lamp Alarm Light Back Rear Led BY DEFENSE FIRE

This little light is cool! It puts lane lights out and is pretty bright. It does consume batteries pretty quick.

The light wouldnt stay on when screwed on, it wasnt tight, I had to fill in spacer area with cardboard to hold light in place, But light is very bright,

These are a great deal for the money and work really well. Everyone who sees them on our bikes wants one so I've re-ordered them a few times. It's so cool to have a laser lane behind your bike at night but be careful because you'll be turning your head around all the time to see the lasers and go off the road.

Worst bike light ever. Received two of them - The first broke after a week. The second after a few days. These things look great on the outside, but somehow managed to screw up the wiring or something for a simple light! If you shake or knock these things, they turn off. Piece of junk - do not buy.

Nice, but not water resistant. First time in a light rain, water got inside and shorted out an on/off button and one of the lasers. The short in the button meant the lasers wouldn't turn off, which meant dead battery. After drying out, the on/off button works again, but one of the two lasers does not. In addition, the light doesn't clip securely into the seatpost attachment. Bumpy terrain can result in the light falling to the ground and breaking. You can try wrapping a rubberband or ziptie around the clip. But then you have to deal with the rubberband or ziptie every time you want to remove the light, including whenever you replace (or, in my case, recharge) the batteries.

Showed up on time, great value. Got to share one with a friend and took about 5-6 minutes to install. Lights are bright and crisp and I'm happy with them.

Very cool, not quite as bright as image would lead.

Purchased two lights. One works well, the other is questionable with the switches and the mounting bracket. I will spend more on a better product when these go completely bad. Will not purchase the same item next time.
