I am frustrated with the Moab and NiteRider. I got this light a year
ago. It is the brightest light I have seen on the trails. My problem
is that the light does not come on reliably. Kind of a problem. I
called NiteRider and they seem to think that it is the "ballast". In
any case, they want me to send it back with the receipt. Which I
don't have. Yes, I know that is my problem.

If anyone has experience with this light and Niterider, please help.
I am going to Moab and I need to have a reliable light.
