For my setup I use a K-Edge Wahoo Bolt combo mount that allows me to mount a Niterider Mico Lumina 850 under the computer. Very slick, very solid, but not cheap. But you have a setup that allows you to use the light as a headlight, or a "see me" device at lower lumens. Very flexible. The tail light is a standart Cygolight rechargeable. Nice and bright.
