So I had a bit of a stack in the bush off Halcyon Avenue on the sniggle leading to Springwood Ridge and Grose Head South. I had a Knog Blinder 4 led light on the back of my helmet and when I hit the ground I think it jarred loose. The clip was still stuck in my helmet. It is the red GT stripe model with a black silicone band. If anyone finds it, it would be cool to get it back. Ta.
