I would like to add and indicator light to a system. It has to be bright, so LED.

However, the signal source for that indicator cannot provide enough current for even a basic LED. I don't want to design whole circuit to amplify a signal. Are there any components that are simply indicators with built-in amplifier (so they take GND, 5V and on/off signal for example)?

EDIT: I know that could be done with 3-4 additional elements (transistor, few resistors). I just hoped that this is frequent enough use case for an indicator that something like this would exist as a integrated component, and that I just cannot find it (not knowing how it is actually called). I am searching Farnell and google but it seems that I cannot figure out the proper keywords for such functionality.
