I've got a beta rev 3 and have purchased a front light for it is there any way I can connect it with out a battery thanks Dan

It depends on what type of light.

If it's a proper light for a trials bike, Look on the beta website for a wiring diagram it will show you how it's connected, You will also need a switch.

It's probably better to get a friend who has a basic knowledge of this sort of stuff to help you.

If you are fitting a standard type trials light like most modern bikes come with (LED) you wont see anything in the dark with it anyway!!!

Either way best of luck to you :-)

This is the wiring from 2006 Rev 3
