The ballasts have been improved to require less current on startup to protect the factory wiring and to extend the life of the bulb by not forcing too much power to it at once. Ballasts can also provide constant power to older bulbs which require more voltage to ignite. Output frequency is 250HZ, reducing the chances for electronic feedback which can cause humming in improperly grounded audio systems. Ballasts are more likely to work on vehicles with a Canbus system without additional accessories when compared to the DDM HID kit but still may require additional accessories for some vehicles. Designed to last 10-15 years.
Included: Set (2X) or Single (1X) Ultra Ballasts & Igniters (built-into ballast)
Warranty: 1 Year
