For road use I did not want an overly bright headlight pissing off and blinding oncoming drivers on my rural commute.
Got one of these and it is just right. Bright enough but not too bright.

Have a well equipped shop and am handy at plastic forming so I made a clip on swivel mount out of sched. 80 ABS that allows me ot swivel the light up/down, back forth with one hand. This has come in handy to "wake up" inattentive drivers.
