From the owner's manual:
The LEDs on the panel indicate the following:
C= Charge at 12.7 volts
G = Good at 12.1 volts
F = Fair at 11.6 volts
L = Low at 6.0 volts

The lights are for lead acid batteries, but IMHO not really that useful. The fourth light typically only comes on when plugged into shore power. The third light goes at 12.1V, or just below 50% SOC. The second light stays on until 11.6V, or a completely discharged battery. Much better to get a digital voltmeter or a real (shunt-based) battery monitor so you can know the state of your batteries.

I have not installed one (I have lithium batteries that report their SOC so I don't need one) but I don't think they are particularly hard to install. Many on here have installed the Victron BMV-712.

No the shunt is not hard to install, I installed the victron 712 for my lithium battery. Get some ring terminals that fit your battery ground wire and the bolts on the shunt, cut the ground wire somewhere near the battery and crimp or solder the rings on. Connect the shunt to the rings, run a wire from the positive post to the shunt, and communication wire from shunt to the display unit. Should take less than ten minutes. Just make sure the shunt is the only thing directly connected to the battery negative post.

Smart Shunt

I installed the Victron Smart Shunt 2 weeks ago, and it took me about a half hour. It's bluetooth so I can see what's going on from both inside the camper and inside the truck.

Notice the bottom picture is what I see on my phone. This photo shows at the current rate of discharge I have only 8h 19m before I reach 50% in my battery. This was my first configuration and the current status doesn't show numbers like this... fortunately.
