Were I live the Law tells that atv's must have signals, because there we can ride on public road, as normal motorbikes. In my avatar u can see front signals on my Grizz. There are small signal, the same used for bikes.
In this pic u can see how looks the Griz in Italy, with signals and the ORRIBLE light, in the middle, due to the law.
It is the first mod i will made, poicking it off, on my new 700 that i just ordered to the dealer.
