944 Headlights in LED

Meh, you might get some voltage drop but you can get plenty of light and harnesses, relays, etc. will present their own problems. You should have less than 0.5v drop I think, or you have other problems. No big deal.
I prefer the color of 3700K HID to the 6500K LEDs but the 6500K LEDs are pretty good and I do not think it'd really cause eyestrain. I think that's a myth that people who sell gamer glasses made up. I'll manage.
LED drop-ins have gotten a LOT better in the last 6 months for what it's worth. I do wish the color was better, hopefully warmer colors are in the offing.

Trust me on this...I often use my LED light bars (putting out the blue-white light) as primary headlights for long highway drives (for some reason I don't like to put the pop-ups up for high speed lol)
After an hour or so the eyes kind of hurt...so I slow down and put the pop-ups on.
On the same trip but using pop-ups, no issue.

My eyes feel better now at the end of the day than they did at noon before hand.
Not sure how much of a difference they would make on strain headlight color, though

In fact, I'm thinking about building a mini distribution center for not only the headlights but for the fog lights and radiator cooling fans also. Don't forget the headlights run through the ignition switch on these cars too!

A few years ago I put in the Hella E code harness from Rennbay. Big improvement. However, I seem to burn a lamp once a year. Being one of those guys that has to change both lamps at the same time, I got tired of spending $50 for the good lamps every year. I just put these in:

I like them so far.

With the Rennbay kit comes 2 rubber boots for the back of the headlights. You can't use them without cutting them. I haven't done that yet. I want to see how they are first, so I'm running without. If they seem to work well, I'll cut the boots.
For $50 once, I'll take the risk over $50 every year.

That's why yellow glasses work so well for shooters and drivers at dusk. They take all the blue out of the spectrum. Photographers used to use yellow filters on their cameras esp when shooting black&white shots..my .02 cents.

If you are bothered by the light spectrum from your computer monitor you can simply adjust that and not have to walk around the office looking like Walter from the Big Lebowski.
I'm pretty skeptical of relating the color spectrum to eyestrain, to me in the case of indoor eyestrain it's more of an issue of working your eyes hard looking across one or several monitors and rapidly focusing at different distances, kind of like driving at night or in bad weather vs cruising during daylight hours mostly focused on the middle distance.
Shooting glasses are often yellow to increase contrast for paper targets, there could be some sharpening effect as different wavelengths refract and scatter differently (see a sunset) but I do not think this is significant in computer monitor distances and it should not be an issue with LED headlights which are not very broad spectrum.
Filters on cameras are a different deal since shorter wavelengths have a lot of energy and I do not think CCDs or films are as good at discriminating, and they are more of a reaction to outdoor light than something used indoors or with a flash were the shooter is in control of the light spectrum.
I do not know why foglights and French headlights used to be yellow and aren't anymore.
Regarding auto bulbs, I have tried several colors of HID bulb in my Audi and definitely liked 4200K OEM the best, I will be looking for some LED bulbs in that color temperature range for my truck when they become available but for now the 6500K are what I can get and they are way better than the stock halogens. Thankfully stock 928 and 968 lamps are excellent and I have not been moved to upgrade them like i did with the 944 US-spec lamps.

While you may be happy with your LED bulbs, the fact you were going through H4 bulbs every year may suggest you have another issue, perhaps the alternator voltage regulator is suspect...or you were just buying not-so-good bulbs?
I don't think I've changed any lightbulbs on my 944 since 2006. When I went from US-H4 to Euro-H4 I just re-used the same bulbs in the new housing.
And my Subaru still has the same bulbs in it from when I bought it ~2 years ago...and who knows when the PO put those in.
Stay away from the "silverstar" or the "hotter than normal" lights for a given wattage, and you should be good...even the cheap basic 55W store-brand bulbs.

So, I grabbed a set of LED bulbs that drop into H4 lenses after reading this thread in the 928 forum (specifically, third post on that page). Doesn't look like that seller has H4 bulbs available on AMZN currently, but that style is working fairly well for me on my S2.

Here are some links and pics (comparing factory to l.e.d. And High and low beam. (page 5 and 6) of the budget LEDS ($160 for two.... Duh!)
I put in my 944.... Sort answer..... I really like them.... May add a set to my jeep for good measure!

I'm running the stock H4 setup with "+40% light" Osram bulbs and they are great. Yep, the name sounds like it came from China but it really is great. Got them for 2-3 years now and still love 'em.
The newest LED/laser lights are a little better imo, but even at 130 km/h on the empty motorway I don't feel the need to turn on high beam.
Cheap, easy, reliable, best bang for bucks.
