The H4 CREE LED headlight kit I am using came complete with 2 ballasts, 2 -25W Cree LED bulbs, cooling fans,and easy to follow instructions. The kit showed up in less than 5 days after ordering and was VERY securely wrapped. The best thing about this whole kit was that it was very much Plug-And-Play. You simply mount the ballasts, install the bulbs, and plug in to the existing headlight connectors. It was literally that simple. Another nice thing about the kit is that the LED bulbs actually draw less power than the factory bulbs. The Cree LED bulbs are rated for 1800 Lumens (very similar to the light output of car HID headlights in say, Mercedes Benz and Lexus automobiles) and the color temperature of the bulbs is 5000 K (compared to standard car HID's at 4300 K).
