Installation of the IPF high intensity bulbs requires use of IPF's H4 Halogen headlight inserts, which are available to fit most standard rectangle or 7-inch-round Halogen or sealed-beam vehicle headlight assemblies. IPF headlight inserts feature a double-coated, prism and column cut lens made from 3/8-inch hardened and polished glass. The lens is designed to resist rocks and chips, as well as against high heat situations.
