Due to early and late riding, including winter, the backlight has been important for me too. While I had some trial detours, I invariably went back to Sigma computers, currently wired 16.12. There is a wireless version of that computer too. The pros of the Sigma computers include: backlight, reasonably accurate clock, good contrast, display working fine at low temperatures, memory when changing battery. The cons include: cumbersome operation in terms of buttons, flimsy mount, marginal temperature function.
