H4/L HID kit includes 2 HID bulbs and 2 Canbus Pro ballasts. H4/L indicates a dual bulb where a small halogen bulb is used for high beams and daytime running lights, and a xenon bulb is used for low beams. This setup upgrades H4 halogen bulbs to HID without using a relay. Daytime runing light is the high beam, and because it uses a small halgen bulb, you don't have to worry about low voltage which normally would not work with HIDs.
