(remember, your battery has a HUGE amount of current to deliver, but at a lower voltage than your alternator so you get the light dimming) A cap buffers this out by storing a large amount of energy at the alternators voltage, and discharging and recharging it very quickly iliminating the need to fall abck on your batteries current. Wise installers always say "the battery is to start your car and use electronics/lights with the car turned OFF..once your car is running it should serve NO purpose"
