Dim All the Lights was created in 1995.
When the bass hits in your car the headlights will dim if you have enough power. Installing a capacitor (the capacitor stores power and creates a buffer) absorbs this surge and your headlights don't dim. Not unlike a capcitor in your home airconditioner. Without a capacitor, your house lights would dim when it turned on.
You should dim your lights as soon as you see their lights.
