it looks nice and clean around the battery. I have a positive ground 1964 Triumph TR6 that I converted to 12v, but left positive ground. (I wouldn't have known how to convert it to negative ground.) All of the LED bulbs Ive tried have worked fine, including LED headlight bulbs. Are there more options for LED light bulbs with negative ground?

The standard LED car bulbs I tried didn't work with negative ground, I have 2 other bikes (both BSA's circa 1970) which I have also converted to neg ground and fitted the modern later rectifier and have automotive LED lighting. The conversion is remove the old plate rectifier and disconnect the zennor diode, swap the wiring over at the ammeter on the 2 terminals, swap the wiring over on the low tension side of the 2 terminals on the coils and obviously the battery. I also run my GoPro and plug in my phone charging cable from a 12 to 5 volt converter off the bike.

hi dave you can get positive earth as well so no need to change every thing, but just be aware that some led bulbs need a relay to stop them from flashing or blinking and you can get led bulbs that can cope with 6 volt right threw to 24 volt hope that helps and you can get led bulbs that can work with either neg/or/ positive it doesn't matter, kind regards Adrian.
