Schematics

Two LEDs with limit resistors

It doesn't get much simpler!

More powerful display with 3W LEDs

Using NPN transistors like the TIP122 you can drive higher wattage LEDs for a brighter display

3W LEDs behind cutout and translucent panel

One way to create a highly effective display is to mount the 3W LEDs behind a translucent panel and then place a laser-cut or vinyl-cut (or hand-cut with scalpel) template over the top.
