The H5 headlight fitting - unnecessarily complex? Apparently not ....... if you're German! |

Changing a headlight bulb in your RS America - a 12 step program. |

How difficult can it be to change a headlight bulb? |
||
The premise is very simple. Undo a few screws, remove a trim ring, remove a couple more screws, pull the light unit out of the car, whip out the old bulb, in with the new and then do everything in reverse. Simple .... right? |
||
The changing of the bulb. |
||
I've never been very happy with the poor light output of the stock H5 headlights that my RS America. came with when I bought it. I'd heard a lot of good things about the Silver star Osram replacement bulbs, so I decided to replace my bulbs with the 9004 style bulb. |

The tools you require to perform this task are few and readily available in most toolkit's. |

Step 7) Install the while headlight bulb locking ring and lock in place by turning clockwise. |
||
Step 8) Now would be a good time to clean the headlight bucket (and for the more anal of you to wax it .....) if you so desire. |
||
Step 9) Pick up the headlight assembly and plug in the headlight. |
||
Step 10) Holding the headlight assembly in place, install the four mounting screws, this is when the magnetic feature of the screwdriver really comes in handy once again as the screws are slightly offset so access is not as easy as it could be. |
||
Step 11) After mounting the headlight, start the engine and turn on the headlights to test both the high and low beams. Check the pattern against the headlight you haven't changed yet and adjust the light with the two adjustment screws. One is on the top and the other is on the left side of the headlight assembly. If you didn't move these screws, then at most just a slight adjustment will be needed. |
||
Step 12) Install the headlight trim ring and screw and you're done and ready to do the other headlight.. |
||
TOTAL Time: 10 minutes per light. |
||
Notes. |
||
I discovered 80/100 watt bulbs in my headlights. The Silver star Osram bulbs only come in a 45/65 watt size for the 9004 style H5 headlights, yet the light is noticeably brighter. Porsche's headlight wiring system integrates the headlight switch in the circuit, so using a bulb over 100 watts can overload (overheat) the wiring in the circuit and is not recommended. Headlight bulbs over 100 watts should only be used after installing a headlight relay system. Using the Silverstar bulbs (45/65 watt) actually decreases system wiring load while giving a better driving light. |
