The headlamps come in either chrome or a black painted finish. There is a factory cover plate that fits around the outer headlamp rim (covering up the chrome or black), that is primered, and can be painted the color of your car. However, to install this cover rim, you also need to replace the single lower attachment screw for the entire assembly with the inner and outer screws listed below. The inner screw actually fits inside the outer screw and holds the primer ring to the assembly.

Most replacement parts for H4s are unavailable in the United States due to import restrictions on the parts. Porsche will not import replacement parts that were only used on European cars for DOT concerns. As a result, only a few replacement H4 parts are available. If you would like to replace the retaining ring, reflector, or even the outer black or chrome ring, you will need to purchase an entire H4 assembly. The H4s have an additional small bulb inside the assembly that is used for daytime running lights on European cars. The US-spec cars do not have the wiring installed to utilize this feature of the H4s. Please Note: These units Do Not come with Bulbs. You will need part number 999-631-034-90-M44 below.
