recently purchased some flashing leds.installed resistor,hooked up,will not flash,tried several leds ,same outcome. wired them the same as reg leds(non flashing).question is,do you have to do something diff.for a flashing led?
thanks rich

Try reversing the LED leads (wires coming from the LED).
LEDs are polarity sensitive. They will not work at all if they are hooked up backwards.
If you're running these in a locomotive, you need more than a diode and a resistor, you MUST have a filter capacitor to make smoothed DC. The flashing LED has a tiny logic circuit that actually does the flashing, if it is running on half-wave DC from a diode, or even full-wave DC from a bridge rectifier, the flash circuit won't work.
They don't need regulated DC, but they do need filtered DC.
Note that regular LED's run fine with a diode and a resistor off AC power.
