Dinotte 300r on my bike. Steady low power, with high output flash about every second. Very effective. I believe the flash should be the brighter light, the flash isn't as effective if it is near a steady light that is brighter than its pulse. IMO anyway.

YOu need serious rear lighting for traffic to take you seriously, IMO. You need serious front lighting for you to take the road seriously. In this day and age, marvelous lighting is available. Expensive, but once you ride with great lights, you won't go back to rinky dink lighting. 300 plus lumen's in front as a minimum, 140 rear? Save up for it if you have to. Or Be really, really good and make sure Santa knows it!
