DIFFERENCES BETWEEN ALL THE BALLASTS/KITS WE OFFER!

We offer 4 types of ballasts for our kits.  They are, 35w DC, 35w AC, 55w AC and 35w AC Slim.  The main differences are that the 35w DC ballasts are cheaper and will fail if your electrical system is not in tip top shape.  The 35w AC ballasts are designed to take some pretty good abuse and are about 20% brighter than the cheaper 35w DC ballasts.  The 55w AC ballasts are about 60% brighter than the 35w DC and 40% brighter than the 35w AC ballasts.  The 35w AC Slim ballasts are designed for extreme low voltage situations that are present in tucked engine bays or motorcycles.  These are nearly as bright as the 55w AC ballasts, but again will take more abuse than any of the other ballasts mentioned.
