Death proof, I used an online LED/resistor calculator to figure the correct resistor. I will post which LEDs and resistors I used for the flamethrowers tomorrow. I then wired it from the battery positive (9v) to one of the momentary switches (button on the flamethrower, then the resistor, and then the LED. After that I did a negative from the LED to the battery. I did that for both flamethrower nozzles. Solder stuff is fairly inexpensive and easy to use, just don't forget to flux the wires before soldering. I wired the led on top with no switch so it's on anytime the battery is connected.
As I said, I will post the LEDs, resistors, and switches tomorrow. I am no electrician and I figured it out in a couple of days with no experience (save the web), and with my list of parts you can do it too without the trial and error
