Defective Battery Charger

Hi, I need to return this battery charger.

Sure, is there anything wrong with it?

Yeah, it doesn't work.  Can I trade it for another one?

OK, let's plug it in and see what's going on... it has power... the battery's charging... what's the problem?

None of these lights work.

The lights?

Yeah, these indicator lights down here.

Oh.  Those aren't lights.

What?

There are two indicator lights here at the top, green and red.  What you are looking at is a decal explaining what the lights are doing.  Quick flash, slow flash, steady, see?

Those aren't lights?

Nope.  And this charger seems to be perfectly fine.

...

OK, so I'm an idiot.

I would never say that, sir.
