I have been thinking about using a moped head light since it probably has a good road beam.
Ok, its not a moped but here is the low beam from my Vespa lx150. Its goes a little faster than my bicycle.
Its "enough" light.
All photos F3.5 2s shutter.
And here is my quad cree MTB light on wide beam (500mA).
And here is my road light dual cree Q5 at 1A
The vespa is a 45w halogen. Its sharply defined.
The MTB light has more spill and a similar width.
The road bike has much better throw.
I would not want to go for a ride through the dark woods on the Vespa. I don't ride it in lycra either.
