If your trying to make LED signals work, you'll need a pretty high current diode. Radio Shack has a 3A 50 V model that would work.
For indicator lights, I'm not sure. You'll have to look at the wattage of the incandescent bulb you're replacing, and calculate your current draw using Ohm's Law "Voltage (V)=Current (I)*Resistance (R), and Power (W) = Voltage (V) * Current (I).
For instance a 12 W light, at 12 V would use 1 Amp of power. The resistance of that circuit would have to be 12 ohms.
