Ahhh but is it a voltmeter ?
Its part of a universal 52mm gauge set I'm making.
The one in the picture is a 9-16 volt meter.
It is microprocessor controlled (no analogue pants here
You can use it in bar graph mode, single dot mode and it can be linked to your amp to give light to music as well (seperate input and it can switch between the two).
It also has a "show mode" for when you're showing off the car - alternating lights as shown in the picture and more .......
Other gauges I'm making are a lambda sensor gauge (0-1 volt), oil pressure gauge, tachometer, temperature gauge, gear shift change (programmable) gauge and a fuel gauge
You can have any combination of colours - red, yellow, orange, green and blue on the gauge and they can be in any position you want.
I've designed these so they can be fitted into a standard 52mm pod. Its early days for development at the moment and I'm going to be doing a fair bit of testing before I release them as products but I'm getting there
