Unhappy Yanmar Tachometer lights

My control panel tachometer has dead lights, needed for night passages.
On the back of my panel (see attached pic) I can:

1- assume those are the lights, but deeply recessed. If they are, what tool can I use to extract them? Long needle hose pliers barely fit, but I don't have much grasp. Are they screwed in, 1/4 twist or pull?
2- three 6-point star screws that I would need to unscrew to remove the white cylindrical cover? Safe to do so?
3- this is probably a warranty seal, I'd need to break for the last screw.

I don't seem to find any part number for these lights, any clue?

Re: Yanmar Tachometer lights

You need lights?

Our tachometer is in the cabin, but I sure know what the engine sounds like at various speeds

Probably quarter turn, similar to Japanese car (auto) panel)

Yes and safe if you are careful!

3- this is probably a warranty seal, I'd need to break for the last screw.

Unlikely to be warranty seal, such seals are generally labeled as such. More likely a dust cover for a factory setting / adjustment point, maybe for tach pulses or somewhat. Anyway, is it still under warranty, if not, who cares!

I don't seem to find any part number for these lights, any clue?

If they are quarter turn, then maybe a wedge style car dash lamp.
Do let us know how the job turns out.

Re: seal,
There was probably something written on it 14 years ago...

Re: Yanmar Tachometer lights

6 pointed screws are Torx screws ! You don't need to bother as the bulbs will just twist out as they are standard bayonet bulbs. I would go on ebay and find the equivalent bulbs in red led !https://www.ebay.com/itm/10PCS-T5-B8...3ojR:rk:8:pf:0

I did it last week. I removed the 3 torx screws and completely opened up the tacho. Took this opportunity to polish the plexi, much better now ! You will need a small flat screwdriver to pull the two plexi layers out.

A quarter turn to remove light & housing. You can keep to housing and change only the light. Very cheap and available in most shops. The other link on ebay with complete housing & LEDs looks very nice though.
