This most likely will be a dumb question, but I purchased a Fierce Audio capacitor, model FEC1D. When I opened the package it came with all the installation stuff. It also came with this item that looks like a resistor or a light bulb. I know a resistor is needed in order to charge the capacitor, but do any of you know which one it would be. If it is a light bulb, do I also then need a resistor or is the light bulb sufficient?
