Two, one at each end of the bike. Each light casts its own section of the spider pattern and the sections link up on the road. Kitting out two bikes? The 4-pack covers both.

One light with its own strap, mount and USB cable. On its own it's a complete LED and laser rear light. You'll just see part of the pattern instead of all of it.

Press LD and a low-power red laser casts glowing lines on the road. Add a second light at the other end of the bike and the two sections link up into one spider pattern. It looks its best at dusk and at night, and road surface changes how it appears. In daylight, the LED strip does the work.

Yes. There's one button for the LED strip and one for the laser. The LED has steady, flash 1 and flash 2. The laser has steady, slow flash and fast flash. Run the LED alone in daylight, add the laser after dark, or use both together.

The red LED strip is made to be seen day and night. Flashing modes are the most eye-catching in daylight. The laser lines are a low-light feature and won't be very visible in direct sunlight.

The laser is low-power and points down at the road, not at drivers. As with any laser product, never look into the beam or point it at people, animals or vehicles, and keep it away from young children.

We'd keep the red LED for the rear light, since forward-facing red lights are restricted in many areas. Up front, run the laser only, alongside your usual white headlight.

A red rear light is required or recommended for night riding across the US, and LaneHalo is a red rear light first. The laser is an extra visibility feature. On the handlebar, use the laser only, since forward-facing red lights are restricted in many areas. Rules vary by state and city, so check your local regulations if you're unsure.

Yes. The stretchy silicone strap goes around round, aero and D-shaped seat posts as well as handlebars, on road, city, mountain and e-bikes. No tools needed.

Wrap the strap around your seat post or handlebar, hook it onto the mount and tilt the light so the laser points at the road. It takes a few seconds per light, no tools needed, and it comes off just as fast when you park.

Yes. It is IPX5 water resistant, so rain and road spray are fine. Just don't submerge it.

Plug it in with the included USB cable. A full charge of the 500 mAh battery takes about 2 hours. With the LED and laser both on, it runs about 2.5 hours steady, 5 hours on flash 1 and 7 hours on flash 2.
