So it would be wise to do the right thing and replace them with LEDs, and they will last tens of thousands of hours. 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.
