This is a great part for any Porsche with a 7" sealed beam headlight. This is a new great quality headlight beam with a 12v H4 60/55W bulb. This replaces the old sealed beams that you have to replace completely when it burns out. This way you just replace the H4 Bulb very easy an simple. You don't need any extra wiring or do any changes. Your wiring the wiring socket on the bulb fits the same as your old 'sealed' beam original in your car. This gives you a really nice bright light with the Halogen H4 bulb 55/60W included.
