Review: Great helmet light! - I love this little helmet light for my dusk/night riding. It is small and lightweight. It effortlessly clips into my helmet and stays charged for at least two hour long bike rides. I wouldn’t use this as my only light source, because the beam is feather wide. It makes me more visible to oncoming traffic and it is an excellent secondary light source for my night rides. I use this in tandem with a small light mounted to my handle bars and that is the perfect amount of light. I love the flashing red light in the back. It makes me feel more visible to traffic when I am riding at dusk or in the absolute dark.
Review: An outstanding light with excellent customer service - I am using this light on my commute from Bainbridge Island to Seattle. I have received compliments for its visibility in broad daylight. The light is meant to be seen, not to provide illumination. It is easy to mount and has a very intuitive interface with many lighting options. A cool feature is that it remembers last option used. Only trouble I have had is with charging it (which it needs very infrequently). After only a few charges, the receptacle in the light for the USB charger in the light became dislodged and I could no longer charge the light - this may have been operator error (perhaps not being gentle enough inserting the charger into the light). Even though it was months past my purchase, and past the return date, I was impressed that I was sent a new light all the way from England, from the engineer himself! That's customer service! I recommend this light very highly - just be gentle charging it.

It can be used as a bike front light or as a bike rear light or as both a front and rear bike light set. Weighing just 2.3oz it is hardly noticed when used. The LED bike helmet light gives out a powerful 100 lumen flash but as it has a wide angle lens does not give a blinding beam to drivers.

The recharge takes only 3 hours and the light will last from 2.5 to 43 hours depending on the mode used. With upgraded and brighter LEDs, improved charge and run time and stronger mounts, the Topside 2 is a much improved safety light.
- LIGHT AND SECURE: The Brightside light will mount to almost all helmets with clips and straps included. The 2 in 1 light Topside can also be mounted to your handlebars and used as a bike front light. The dual front and rear bike light light can also be used as an electric scooter light, a mobility scoter light, wheelchair light, rowing light and many other uses.
- IDEAL FOR ALL CYCLISTS: The dual front and rear bike light is an ideal commuter bike light. With the mounting clips and straps included in the box, fitting it to your bike helmet is simple and the Brightside light will fit almost any bike helmet.. No tools or sticky tape are needed and as the bike light mount is held by a rubber strap the light can move if need be.

## Questions & Answers

**Q: Can both light work in different modes at the same time . Like front light stays on While back light flashes.?**
A: Yes, each light can be in a different mode from the other.  The front CAN be continuous while the back flashes and vice versa.

**Q: How well does this illuminate the road?**
A: This light is intended to be seen and not to see far ahead - I would pair this light w an actual bicycle headlight of 800 lumens or more

**Q: Is the non-blinking setting putting out enough light to get the attention of drivers during the day?**
A: Hi. It really depends on the amount of light - as I'm sure you can imagine. If you're in bright sunlight then a lot of lights will struggle but in the shade or a clouded sky then yes, they can be seen. The Topside light has a 100 lumen flash. Hhere are much brighter lights available but the design takes battery life, weight, size etc etc into account so having a 250 lumen++ light would compromise other features. They are great lights and are used by lots of cyclists. Hope that helps. Brightside

**Q: can you mount to helment?**
A: Yes. It comes with two different styles of mounting brackets and some zip ties to hold the bracket in place. I found the zip ties to be too short for my helmet and had to use some longer ones. It is very secure once you get it mounted. Light weight too!
