Setup and Installation
Follow these steps to properly install your Minsk W605 Bicycle Headlight:
Prepare the Handlebar:
Ensure the handlebar area where the light will be mounted is clean and free of obstructions. Place the non-slip silicone gaskets around the handlebar at the desired mounting position.
Attach the Brackets:
Open the aluminum brackets and position them over the silicone gaskets on the handlebar. Securely fasten the brackets using the provided screws and Allen wrench. Ensure they are tight enough to prevent movement but do not overtighten.

This image shows the four steps for easy installation: 1. Placing mounting spacers on the handlebar. 2. Fixing the base of the brackets onto the handlebar. 3. Clipping the bike light into the lamp slot on the fixed base. 4. Tightening the screws to secure the light.
Mount the Light:
Slide the Minsk W605 Bicycle Headlight onto the fixed base of the aluminum brackets until it clicks securely into place. The light should be facing forward and level with the ground.
Adjust and Secure:
Adjust the angle of the light as needed for optimal visibility. Ensure all screws are tightened to prevent the light from shifting during rides.
