The taillight with lasers draws two bright red lines on the road, thereby indicating the dimensions of the bike. The flashlight is powered by two standard batteries. Very bright and noticeable in the dark.
It has 2 buttons: with one button the lasers are turned on, the second LEDs. A bicycle lamp with lasers will increase your safety on the road in the dark.
Very easy to install.
Strip colors (optional): red / blue
