I don't feel safe on unlighted rural roads without at least 300 lumen headlight.

Was running a 250 lumen light on my helmet, but after a cop out-chickened me with their spotlight and pedestrians said "Ow!", I ditched the over-bright headlight idea and put that light on my handlebars. Now running a sub-100 lumen light on the helmet, set to blinky. Seems to have the same desired effect.

I purchased an E3 Supernova asymmetric light (around 300+ lumens) for my dynamo setup not knowing that it was a shaped beam, but it works great, would not go with their off-road symmetric beam version.
