I got around to fitting a Gammatronix battery level / charging indicator today. I took the supply from the infamous spare connecter behind the dash so it's switched & also comes on with the key in park light position as a handy reminder when the bike gets parked up in a hurry. I bought it off eBay as suggested by Pleiades (Thanks mate) it was a simple fit. Glows green when all is well, yellow when somethings not so well & red when there's a real problem.
Some spot lights are next on the list.
