I have had a standard, non-lighted Clocks4Bikes clock for about 2 years now (stem nut mount) and I just saw the new electro-clock one so I just called and they are sending me a lighted model to fit my stem nut mount for $15.00.
Great clocks and the stem nut mount is perfect for the america and speedmaster.
