Experienced cyclist here, but never rode in the dark before. And I do not know beans about riding lights, though I have quite a few rear blinking lights. I am thinking I'll like to start doing two/three hour rides after dark. Could you recommend a reliable $30-$50 front light that is reliable and quite bright to cover me tooling at 25MPH and can last the duration of my rides? A good solid mount is also cool. And if the price is right, I am not opposed to getting two and mounting one on the helmet too.

Thanks.
