My experience with Dinotte lights:
At first I wasn't a big Dinotte fan but after a few changes to my set up I will not leave home with out my Dinotte light. I use the helmet mount that came with my Stella lights (that I have on the bar) to mount my 200 Dinotte (I like it better). Photos are of my helmet as I ride during the day time and with the light mounted for night riding. Dinottes customer service is excellent. I had issues with my first light and they took care of it very well. I will upgrade to more Dinotte power and additional Dinotte lights as time and funds permit.
