I replaced a grain-of-wheat lightbulb for a clock-radio dial with one from
Radio Shack. The supply voltage is 5 volts so I bought a 12 volt bulb.
Imagine my surprise when these damned things are only rated for 15
hours!!!!
Are there any 5 volt LEDs around?
Any LED can be a 5 volt LED with an appropriate dropping resistor. ;-)
That being said, there *is* an LED rated for operation directly from a 5
volt line. Unfortunately, it's a flasher.
