Switching a light bulb in a power button on a Lisa?

Ok. I bought a replacement bulb for the power button of my Lisa. (type 87 T1 3/4)

I worked the complete power button out to make it easier to remove the light bulb. But I have no clue how to get it out....

Should I pull, turn?

It is impossible to do it with your hands, but it also seems impossible to open the power button.

Anyone knows what to do?

See picture:

That metal tab on the bottom of the button. Use a flat bade screwdriver or something to lift it and then pull it to eject the bulb.

Wowww! Thanks very much. That does the trick! I was a little enthusiastic so the bulb launched like a rocket....

But ..it came out.

Now the replacement is in. Bought it on a historic radio fair. Yes ... I also collect old radio's.

See how this NVHR fair looks....old movie...but still the same:

Nice! Always like to see these old girls running - especially with LisaOS

The bulbs are oddly the same or near identical things that I use in my DEC's RA82 disk drive and my car's instrument cluster.

How about running a red LED down there as well, and use that diffused area for a HDD activity light?

....why? You already have a location for an HDD activity LED on the front bezel.

Oh, didn't know that. Carry on, then.
