2002 Cabo electric panel red "on" lights

Sounds like you have an in-line bus fuse blown or lose. It would be in the common line delivering juice to the all the bulbs.

As it is low voltage, I am inclined to give advice, but considering we are talking electricity, that is maybe not a good idea.
Sounds like a relatively easy diagnose and fix, but giving advice that you action would be irresponsible.
Get a sparky for an hour and fix this. If you can afford a Cabo, you can afford an hour for a qualified person to fix the problem.

You don't need an electrician to look for or even to change a bus fuse, or even to reconnect a wire that's worked its way lose, especially when talking 12v or 24v DC. You can even shut the battery switch if you're afraid of getting tickled. If it gets more serious than that, yes, but even if you can afford a Cabo you don't pay en electricians rate including travel time to change a $2 fuse.

Google: "Bus fuse holder" and you'll see several examples of what you're looking for.

Not sure where your12 V fuse box is located, but it's often right near the helm, generally a little out of the way like low below the helm or a long a side wall near the helm, and that often has button breakers which pop out and you just push back in. However those are usually for things of more voltage than that line of lights; things like wiper motor, helm lights, Nav lights, etc. That's why I think it's an in-line fuse you're looking for, but in theory it could be either.

Follow the wires from the lights to where they go. I cannot remember what the panel on your boat looks like. The digital displays for the power (volts/amps) on some had a small fuse on the back side of the volts/amps. Pay the electricial. It's common for red indicator lights to burn out if they're the ones that are always on such as battery charger and the age of the boat.

That is correct. VERY few things on a Cabo will have fuses. Honestly, diagnosing this problem is beyond your capabilities. First take a multimeter and verify if there is voltage at the indicator light, then if not Following the wires from the panel to where they terminate is very easy in a cabo.

I've had a few electrical issues on my Cabo but haven't had that issue. Seems to me that since each dc light is specific to that breaker there probably isn't a fuse that would impact all the lights on that row. Those panels have a lot of wires, diodes, etc that are beyond my capabilities to help. As Capt J mentions try to check the voltage at the light but my guess is they have electrical to them they just aren't working for whatever reason.

They may share a common ground that isn't attached.

I helped a guy at my marina trouble shoot a similar problem on a different, European type boat.
He had several lights out, his were amber colored, and he could not believe they would all be bad bulbs.
They were all bad.
If you have voltage at the light lead connections and the bulb is out and the wires are not broken then the bulb is shot.
Take a known good bulb and connect it where the suspect is. That will tell the tale.
They are probably all out because they are a pain to get to.

Also the bad ground is a great suggestion.
Good luck

Yes, check grounds, I had that on my Hatteras, nav lite had 13v but bad ground so would not work, fixed the ground an all ok..

There may be a common ground wire that the lights are connected to. Probably not connected any more. FYI: Cabo instrument panels and wiring harnesses were built by a company called "Common Ground" in California. They still supply lights and wiring harness parts to me.
