    I'm not sure if I've been asked this question...
    But, yes, I have proved it is commuting by bike that causes my problem.

    I liked the cutoff of the beam.
    So the add on diffuser helped make this beam change? I think I've seen these advertised.

    BTW, you might want a little more wire length going into the light head...
