TwinStar:
Is there a difference between carbon film and metal film resistors?
I'm thinking I should have majored in electronics instead of aviation.

I assume I'll need 3 of these? One for the mars, one for the emergency stop, and one for the headlight pair?

Correct.

Yes there are differences, however they are inconsequential for your application.
Metal film resistors are more stable at elevated temperatures and they exhibit much lower capacitance at high frequencies. Useless tidbit of knowledge since you are not likely to ever build anything where it would matter. If you decide to build a microwave oven then we should talk. ;D

I wouldn't ever but I have a 13 YO that I'll need to keep my eye on.

Alan,
Out of curiosity, how would using LEDs affect your 317 circuit? Or is it just overkill when an inline resistor will do?
