Neat application of capacitor. It amazing to think that some parallel plates with voltage applied to the plate can store so much charge and instantly release them to make a turn signal flash in a motor cycle. Charging and discharging phenomena in a capacitor is really interesting. Will never forget from my physics class that C is directly proportional to the area of the plates and inversely proportional to the separation between them. A work is done by the applied voltage (battery) to move the charge from one plate to other. A capacitor is charged to a voltage of a battery and there is always a exponential discharge of that stored charge...and there comes the flash in a motorcycle.
