I just recently purchased the 400R after trying out all other rear lights. I should have went with Dinotte to begin with. This 300 lumen light is by far the brightest tail light on the market. I mount mine to my helmet along with the battery. I bring my helmet inside with me as I don't want to leave an expensive light like this on my bike as someone might steal it. Cars weave all the way over to the other lane now.

Call Dinotte and talk to them before you purchase. I asked for 10% off and got it...maybe I should have tried 20%??

You won't regret this purchase as the rear light is the most important part of your bike when riding at night (IMO).

Next fall I plan to get a Dinotte headlight.

Ride safe,

Jeff
