All: Since I do a great deal of night driving, I am adding lights to the car. I've used Hella before and I am considering these http://www.amazon.com/HELLA-12-Volt-55-Watt-Halogen-Driving/dp/B0002MA4T8/ref=sr_1_1?ie=UTF8&qid=1446860656&sr=8-1&keywords=hella+1000+black+magic My question is the alternator. Will I need to upgrade it for the additional power?
