Stock radio lights

[skrappi]

Some of the lights on my stock radio do not work. Light the number 1,2,3,4, buttons for the radio stations. The other lights work. Are these LED's? Or is there a set of bulbs in the background somewhere I can replace?

FYI, 97 Malibu. Stock AM/FM cassette player.

Thanks!

I've taken the radio out before and I don't think that there are any servicable parts inside the radio...almost positive their LED's
