Two halogen bulbs that came off our 2003 jeep . One is a Wagner BriteLite 12v 60/50W 2D1 . The other is also a 2D1 and is a General Electric ZN28 . Both say USA Dot on the front . They worked when they were removed but if you have an issue let me know ! Plug harnesses are included . They measure 6 3/4in in diameter
