On the front handlebar I have a Planet Bike one watt light set on flash as my "be seen" light. I run a Magicshine MJ-808 mounted to my helmet that I aim where I want to see. When I come to intersections, I always turn my headlamp beam through all oncoming drivers so they know I'm there. I don't do it to the point they are blinded, just to the point they're aware I'm an oncoming vehicle.
