The bike light is designed to be mounted on the left side of the bike, which functions best in countries with right hand traffic, since the light then is closer to traffic.
If you should be in a country with left hand traffic the light can still be seen through the spokes.
The light can be mounted upside down on the right side but it will result in a light that points up a bit due to the angle on the lens. Alternatively you can swap the front and rear light PCB's which only requires a small phillips screwdriver. A guide for both options will be put up shortly.
