Re: LED's

There are plenty of LED lamps now of various colours with build-in resistors
e.g. for direct 12v input. In UK  see RS catalogue.

Just occasionally you don't want a low current lamp.   I have a tone-burst
generator for undercarriage warning which is shorted out when the gear is
down. It is fed through a green lamp which  illuminates when the gear is down
- but if it were an LED there wouldn't  be enough current to actuate the tone
in the gear up position.
