Because I run power via a fuse from the battery I used lights etc that can cope.@trevor brooker - must say I do like your indicators, very wise addtions - could you possibly upload a circuit diagram? I might be able to make room for yet another switch on my handlebar somehow.
I looked though Amazon, Ebay & Aliexpress - they have different colours. Also I remember getting some glass paint to go inside the lens to get the shade I wanted.
For the switches again I looked around until I found those I was happy with.
Then I just got a sheet of paper & a pencil & drew a wiring diagram with Red & Black to make sure I got a circuit. Power from battery to switch to lights then back again.
