CAUTION
Do not look directly at the strobe or LED lights when operating.

Pay attention and care when recovering the USB seal to ensure correct seal so water ingress does not occur. No liability can be accepted for any damage caused by non-compliance with these instructions or any other improper use or mishandling.

The device has a Lithium-Ion battery. When disposing of this, it should be done in compliance with the rules and regulations in your country of residence.

Mounting the bracket

To keep the lights fastened and secure, the rubber rings are provided in two different sizes to provide a snugly wrap around a variety of saddle posts and seat stays.

Start by picking one of the two rubber rings best suited for the size of the saddle posts or seat stay.

Insert one end of the ring into the groove of the bracket (remove the small screw first if it comes pre-installed). Position the bracket on top of the seat post or seat stay. Pull the other end of the ring around the bar and insert it into the other groove. Use the smallest ring possible as this will ensure a more stable mount.
Locate the grey rubber pad from the top bracket and mount the bracket on top of the base part. Insert the screw with the small O-ring and tighten it using the included Allen key.
Insert the grey rubber pad into the top bracket.
Insert the light into the bracket by pushing down as illustrated.
Check that the light is securely mounted into the bracket.
Turn on the light by pressing the button down for 2 seconds.
