riding with Bright Lights

[7rider]

Now this light looks like it could be very useful riding on trails and gravel roads in the dark, which I do occasionally, but for commuting it seems like it could be a hazard unless I'm diligent about aiming the beam.

Any thoughts?

Well. For one, you didn't have a car light shining on her to offset her bright light coming at you. That MAY make your approach more visible (but I'm not sure). Because if you're using a light, chances are, the car is, too.
Also, reflective trim on your gloves, or a reflective band on your wrist might make hand movements more clear.
That could be worth some testing with your friend....and...you could let us know if it works!
