lost my lights

[Andy FZS]

Looking at the wiring diagram on my phone (fzs1000 is the only one on it) the fuse for your head tail and brake lights is the same one. The pass light is a different fuse. The most likely explanation would seem to be that you may not have found the correct fuse or have a poor connection to the fuse. If it was a fault with your light switch your brake light would still work and it was the headlight relay your side lights and brake light would work. So it still looks like a fuse. But I'm not sure what model your bike is and I only have mine on my phone.  Good luck.
