Has anyone done an LED headlight upgrade? My local shop recommends these. Anyone know if they will fit, work well, etc?
THX!

They work, without a doubt. A very worthy upgrade, imo, for our anemic (and potentially dangerous) factory setups.
Fwiw, the GE version had been recommended quite a bit as well. _________________ Toofah King Bad

plus they don't require a ton of added wiring to drive them via huge relays, ballasts, etc.
Most important of course is to ensure your lights are properly aimed, which seems to be a lost art these days. _________________ Stefan

thanks guys. yes after HID/Xenon headlights in my cars for a decade, this baby really needs a modern headlight setup, plus after installing the LED dash light bulbs I am finally motivated to drive her at night, rock out with the roof out! _________________ PCA Licensed Club Racer & Driving Instructor Current P cars: 1981 931

US headlights are pathetic....i dont know how regulations are made over there but they are silly. The 924 ROW headlights are propper headlights that if in good condition still keep up with today's world.
This is my 32 years old 924...with probably 32 years old lightbulbs as i never changed them in @12 years since i own this car.

Morghen,
Thanks. So dumb question but are those H4's? Maybe that would be enough of an upgrade. Certainly a lot less $. _________________ PCA Licensed Club Racer & Driving Instructor Current P cars: 1981 931

Yes they are H4s. You can always buy some ROW headlights for cheap. _________________ https://www.the924.com |

So was the original factory wiring loom spec'd differently for USA vs ROW?
I find it hard to believe that Porsche would deliberately install an inferior spec wiring loom in USA cars to only be sufficient for sealed beams. _________________ 81 RED 931 S2(daily driver),81 WHITE 931 S2(not currently drivable).

+1^
I am running H4s in several of my cars and have not done anything to the wiring harness. As far as I can tell, there is no difference between US and Euro wiring harness, so there should be no problem directly installing H4s into a US-spec car. While the aftermarket relay kit may help with improved grounding and maximum brightness, I personally do not believe it to be a requirement for running H4s. Improved, modern, higher-output alternator helps too. _________________ erstwhile owner of just about every 924 variant ever made |

Irrelevant, unless you have used a time machine to bring forward a new car. We've had members here suffer wiring fires under the dash due to the high current going through the light switch.
The relay setup seems like decently priced insurance compared to the alternative, IMO. _________________ Toofah King Bad

I totally agree that it is wise to upgrade headlight circuits with relays/heavier gauge wiring/ceramic bulb connectors etc especially when using the higher wattage 90/100 even 130/90 H4 bulbs. _________________ 81 RED 931 S2(daily driver),81 WHITE 931 S2(not currently drivable).

Most of the original wiring, but particularly the light circuit, was just barely adequate some 40 years ago when it was designed.

Couldn`t agree more.
As the copper ages it becomes harder & more brittle, then with moisture (and god forbid, salt) in the atmosphere it corrodes, more so at the connector terminations in contact with brass due to electrolysis. The resistance then increases and since current is constant throughout a series circuit, the connection or degraded wiring can become as hot as the light bulb.
The light switch itself is also vulnerable to resistance generated heating and the switch terminals rescind deeper into the melted plastic housing until it fails completely, the circuit becomes open and you end up with no headlights in the middle of the Hay Plains
Either a basic DIY job with a relay and heavier gauge wire direct from the battery, or the commercial equivalent, is highly recommended. _________________ World`s quickest 924 2L slushbox
