Mount only. Please note that the light is not included. This is a mount for the Knog Blinder 900. Everything in the photos is included. Please note that the light is not included. The GoPro mount was installed in April 2025. It was used to secure the light about 15 times. The bicycle is stored indoors and has not been used in the rain. The mount for the other handlebar was attached to a bicycle stored outdoors for about 10 days, during which time it was exposed to rain. Please be careful, as the mount and light can come loose on rough roads if not securely attached. This is a used item, so please check the photos carefully before purchasing.
