Design question: why would you want to spend several hundred(s) of dollars on a tail light for a snowmobile? It reminds me of an article I once read about how the trajectory of technology cannot be determined in advance.
The snowmobile's inventors (Bombardier- Canadians, of course 
) did not foresee people making racks for cases of beers, and the deaths that drinking and snowmobiling would incur! I guess the same goes for imagining that someone would make $500 tail-lights!
