Led under the selector buttons of an 1448?

Hello Germany, did any of you made lights (by leds or otherwise) under the selector buttons of a 1448.

Other brands have them lit, i think it's a pitty that a 1448 only has the red button lit& the first right of it.
(See pic)

So who shares this idea with me?

I think it's easy to make with some leds & resistors on a 12 volt connector (Don't know if 12 volt is provided by the 1448 (otherwise an old PC power supply could do the job)

Did any of you tried something simular ? If so, would you post a picture here please?
