On my bike I use a couple cheap silicone mounts[1] to hold my regular bright LED hand flashlights. I like that the flashlights serve double duty on the bike and that they can be easily removed at my destination.
I'm not so sure about the pricey impression. I bought the Metro 500 USB one yeard ago for 65 USD on Amazon. It has 6 light modes that get you covered may it be during the day, night, heavy rain or snow.
The Metro 500 comes with an easy to remove clip that allows you to keep the mount on the bike while you get your light safe. Handy, but can break in cold weather due to plastic resistance.
