I recently changed some bulbs in my bus on a circuit that was 12V, but that I changed to 24V.

The bulbs in question were oddball bulbs with an odd base, but after doing some internet poking around I found on BulbAmerica a 28V equivalent that was used for an aviation application. They work great.

You can order them from Prevost, but I suspect a little searching will turn up what you are looking for likely less expensive.

Thanks’ Jon I will check it out, I found these 28v mini wedge T1-1/2 ??

I had to go to the manufacturer of the light that used the bulbs I replaced. They listed their part number and fancy name for the bulb used, but listed the wattage. I measured the base and looked at industry standards to find the specific type base, then BulbAmerica has a way to identify all bulbs with that base which allowed me to finally find its 28 volt replacement.

It took some time, but the bulbs showed up in two days, worked and now I am grinning.

Jon: what did you change and why?

I wanted to add a 24V digital gauge with a settable low voltage warning and the easiest way to do it was to use the wires in the center windshield post that were originally for the clock, replaced long ago with a battery powered clock we could see better.

That same circuit however had the reading lights, so I moved the wire from the 12V bus bar to the 24V bus bar and changed the reading lamp bulbs to 24V.
