Save your money they don't work

We ordered 2 of them for 2 of our vehicles to see if it helps to stop our headlights from dimming with every thump of bass in 1 vehicle, and to prolong the life of the new alternator in another. Unfortunately we still see the headlights dimming in the first vehicle, which doesn't make us optomistic about the other one being able to prolong the life of the alternator. The can that's installed shows it's holding over 12v of power, but like I said the headlights are still dimming so this can is doing absolutely NOTHING! I want my money back! We wasted $50 each on this cr p. If that was the case I could have bought the $5 capacitors!
