I have been converting my engines over to LED headlights. In order to stop the light from flickering when running over switches etc. I have discovered that it is possible to add a capacitor to the circuit. What I need to know is what capacitor should be used and how would it be wired. I've seen CLU's for sale on Ebay for around $10 + shipping but I already have the LED's (3 to 3.2 volt) and the resistors (820 ohm) and just need the capacitors.
