Hi all,

I feel like a complete idiot asking this question, but I can't figure it out myself, so.

I recently bought a Kalkhoff Agattu 3 from a friend who can no longer use it, but she'd lost the manual and I can't figure out how to work the lights. The manual I found online talks about a rotating ring at the back of the front light, but there isn't one when I look at the light that's actually on the bike. I asked my friend and she said they work by pressing + and - simultaneously but that seemed to have no effect. Given that this is my first ebike, is there some convention about how ebike lights work that I don't know about? Many thanks.
