1983 31/2 sport warning lights

[barney 66]

I am just checking over the 83 31/2 sport I have just purchased, changed bars for more upright riding position so while doing that greased head bearings and changed fork oil so just assembling clocks and checking bulbs and green warning light not working (no bulb to start with) but I’m confused what it is ?
Is it a light warning to say there on or is it a neutral light ?
Red is labeled oil pressure
Blue main beam
Yellow/Orange indicator warning
Green
Any help appreciated
Thanks for looking

On my 350 K2s, green was a neutral indicator.

Now sorted Thanks, broken wire.
On this it is a light indicator, would have prefered a neutral light but from what I here there not reliable anyway
Thanks barney
