Not sure what the question is. Are you planning to add another bulb socket and leave the existing two? Just tap off the one wire going to the left bulb in the photo. Assuming both bulbs light up, the whole mounting plate is grounded, so you only need the one wire.

If you're replacing the whole fixture (this is what I'd do), you just hook up the two wires. If it's LED, check to be sure you've got the polarity right before making the permanent connection. Of the 14 I replaced, 3 were wired backward. Doesn't really matter for incandescents, but the LEDs don't like it.

I changed all of our bulbs by LED and now our inverter support more than 40 hours

Remove the screws holding the old one to the overhead. Install new fixture.

Remove screws holding old fixture. Remove fixture. Hold new fixture in place while installing new screws in the holes provided.

I would replace the entire fixture if possible, but if in a jiffy, you can replace just the bulbs with LED equivalent: LED Bulbs | Bulbs for Sale | YachtLights.com

Choose the warm white LEDs ... much nicer for the interior and easier on the eyes.

From posts on another thread, OP prefers more light to saving amps, more info on the extra bulb fitting per CaptTom, could help. Is there a vision issue?

Greetings,
Mr. BK. Of course there's a vision issue! Just read some of the OP's posts in OTDE.

Link to the other more descriptive thread would be helpful.

Replacing incandescent bulbs with the LEDs not only saves energy/amps but can generate more white light with less watts ... and runs cooler too.

I have replaced all my lights/bulbs with LEDs. When I used the stronger 3.5W cool white LEDs the light was too bright. I have changed them to 2.2W warm white LEDs and the cabin is lit as it used to be with 7.0W incandescent bulbs (I think there is 7 or 9 in the cabin altogether).

Some experimentation might be required, but the OP might be well served with two strong LED equivalents ... and add one or two more. if still required, as the existing enclosure is large enough. Not much heat and fire hazard with LEDs, and the existing wiring is more than adequate for the LEDs. Adding one or two more incandescent bulbs to the existing enclosure might be more of a problem (wire rating, generated heat, etc.)

I have LED rope lighting behind a wooden valence in the salon for "stumble" lighting. I could replace the dim rope lighting with some bright warm white LED strips for more light in the salon, or just add the strip lighting by tapping off an existing salon light fixture and keep the rope "stumble" lighting. Again, power usage is not a factor but these old eyes need more light.

No reason you couldn't do that ancora, as long as you were happy with the cosmetic outcome. I have done that in the ER in fact. That's the beauty of LEDs, especially the strips. Very versatile and draw so little, tapping into an existing circuit is absolutely fine.

A lot of assumptions have been made, but really, your post is pretty confusing. I'm sure you know what you are trying to ask, but you haven't phrased your question very well.

All I want to do is tap onto an existing light fixture and run wires to another light fixture or LED strip.

Connect the wires that feed the new fixture to the existing wires. Use the same colors and makes sure they are the same gauge as the existing wires so the circuit breaker doesn't have to be changed. Use marine tinned stranded boat wire and marine crimp terminals.

The hardest part may be fishing the wires to the new fixture.

Make sure you are not overloading the existing circuit with additional fixtures and lamps.

Then just some simple butt connectors and your choice of wire is all. Just make sure you use marine grade supply's as Wes stated. Where do you want to run wires to?

Just came across these LED fixtures ... looks like two of these would provide plenty more nicely diffused light than the two existing incandescent bulbs:

I hope you guys will post the longevity you are getting out of these bulbs with boat voltage. I'm skeptical that 12 - 14.5 volts is going to be good for longevity, but I hope you can all reassure me.
