Does Garmin 510 have a light on the speedo
Can the light remain on continuously to view the speedo information.
How much power would this consume riding throughout the night. Would I required the external battery pack to provide a enough power?

Yes you can set the backlight to be on constant or show up at certain time intervals. I have had the backlight on constant as well as a heart rate monitor and cadence machine running and it lasted a 120 mile cycle.
