TLed displays a led-like image with a text-label next to it (left/right/top or bottom). The control works like an ordinary TCheckBox.
What makes it special is the other 9 components included in the package: TCustomLed, TRadioLed, TCustomRadioLed, TLedBox, TRadioLedBox, TDBLed, TCustomDBLed, TDBLedBox and TDBRadioLedBox.
LedBox is a TGroupBox, which allows you to use the leds as binary inputs.
I tested the components with Delphi 2 and 7 plus BCB 5.
Shareware version has 30-day trial period. After that, you will get a nag-window, but no component functions are disabled.
