Light for biker (motorcycle)

[wbarnwell]

Looking for a light for my brother in-law. I'm looking for something in between $25.00-$35.00. I would assume that he needs something small, durable and waterproof that could accomplish a multitude of tasks. I'm not a biker, but maybe some of you are and could help recommend a good light for him. Thanks in advance!

Need way more info to answer this question in a helpful manner. What kind of bike, what kind of lamp (headlamp? Auxiliary lamp? Turn signal lamp? Something else?), what kind of size and mounting...
