Replacing bulbs on my breaker panel

[airdvr1227]

Many of them don't light anymore. While I'm sure there is a standard bulb how difficult is it to replace them?

What panel do you have, airdvr? Some have a screw off/on bezel with the bulb behind it.

Here's a picture of one like mine if it helps. Toggles with circular green lights.
