So has anyone had any success running a higher wattage bulb with the factory equipment?
What's the hightest wattage H7 bulb you've used in your 996/986 headlamp unit?
Use 100w bulb or even a 70-80w

I too would like to know if we can use a 100W bulb or even a 70-80W

Use these as replacements

These bulbs have a blue coating so they shine a bit whiter than uncoated bulbs and more closely match the color of the Litronic headlights (plus they're still rated at 55W so you won't melt your fog light housing.) I wouldn't recommend you use these as replacements for your main beam though because with the blue coating they aren't as bright as the uncoated bulbs.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm looking to replace my headlight bulbs with a more serious higher wattage bulb. I'm not interested in doing a xenon or HID conversion, I just want to use a more powerful offroad grade bulb. I'm also not interested in any of the sylvania or other autozone type bulb upgrades. Can the factory wiring harness and headlamp assembly handle a 80/100watt bulb? My modified Land Rover runs a number of serious auxillary lights, but I still added Hella H4 80/100s to the factory lamp assembly for street duty. I'm aware that this brightness isn't technically legal, I just want to know if it works.
So has anyone had any success running a higher wattage bulb with the factory equipment?
thanks for your help.
I agree with you on the available "over the counter" H7 bulbs, I just put in a set of Sylvania Silverstar bulbs and I am a little disappointed. They are slightly better than the oem bulb but still nowhere near HID intensity IMHO. I would say they are maybe 10% brighter than stock, certainly an improvement but not dramatic. Still a worthwhile experiment given their relatively low price point.
FWIW in the latest Excellence they indicated it was safe to use 80W continuous bulbs with the factory wiring. I would still worry about burning up the plastic around the bulbs though. But I am certainly not a lighting expert. Hopefully there is a more cost effective alternative than a Litronic upgrade, if not I'll just have to suck it up.
The wiring harness can handle it but unfortunately the plastic housing cannot. A higher wattage bulb will generate more heat and melt the plastic lens (and turn it an ugly brown). TRUST ME ON THIS ONE. If you want a brighter, whiter beam then get the Porsche Litronics Retrofit Kit (for 1999 - 2001 cars) or buy the bi-Xenon headlamps, wiring harnesses, etc. and do a custom retrofit (2002+ cars).
Regarding the fog lights... I replaced the H7 fog light bulbs with "XenonMatch" bulbs from H�en (
http://www.hoen-usa.com/fog.htm
). These bulbs have a blue coating so they shine a bit whiter than uncoated bulbs and more closely match the color of the Litronic headlights (plus they're still rated at 55W so you won't melt your fog light housing.) I wouldn't recommend you use these as replacements for your main beam though because with the blue coating they aren't as bright as the uncoated bulbs.
Here are some pictures.
Picture 1: I replaced the H6W city lights with L.E.D.s. The L.E.D.s are definitely not as bright as the stock halogen bulb but they are a lot whiter.
Picture 2: The L.E.D.s look whiter than the Hoen Xenonmatch H7 bulb I got for the foglight.
Picture 3: The L.E.D.s get a little drowned out by the Xenon/Litronic lowbeam but it is a good match. The Hoen Xenonmatch H7 bulb is pretty close to the color of the Xenon lowbeam as well.
