Below is a photo i took at night - its a close-up shot, but should give an indication of brightness:

Will 0.2 make a big difference in the scheme of things?

Given the neatness of the solution, its worth my money.
It all depends on what you're looking for in your volt meter - this is an indication only device that will give you a heads up if a battery is getting low, or not being charged etc. If you want to know, to the nth degree, how much juice your battery is giving you, an expensive multimeter is the way to go.Spilsy

most cheap multimeters would not be that accurate.

I do know that since the AC has been working harder, the charge to the batteries has been lower, averaging about 13.6 v rather than 14. the charge is consistently 14 v when the AC is not blowing cold air. Note, the "AC" Button is always on.Spilsy

Not so much the Ac itself but the fan can certainly load up the alternator. The Ac will bring the voltage down when sitting at idle and and the blower fan us running plus also the condenser fan near the radiator. So not so much the Ac compressor itself but it's ancillaries. Depends how you use it I guess. My AC is nearly always on but fan speed is usually all the way down to 1. So I see maybe 100mV drop. But turn it up.... oh lord have mercy on my alternator!
When I switch on all my accessories at idle, I can easily bring my voltage down below 11. At higher engine speeds I can drop it below 12. I've upgraded my battery to earth strap, battery to engine earth strap, upgraded alternator to fuse block and added a true alternator direct to battery cable. Alternator is healthy... I just have too much shit hanging off of it. Haha

When idling, turning the AC on increases the idle speed, thereby increasing the Voltage !
Maybe this is different for V6 vs Diesel ? Mine is V6.Spilsy
