Phillips LED H4 Headlamps

They are available new from reputable sources like Roger and the like, and available used on eBay. I have sellers who frequently list 928 parts saved as favorites, and will sometimes ping them for hard-to-find parts like these lenses.
I've been searching for a set at my price point for about 2 years, since I know the set sometimes sells for for that magic *sub $400* price tag. I am usually late to the sale, since they tend to sell instantly for any price that starts with a 3. I can attest that finding anything below $400 for a set is next to impossible these days.

OTOH, the picture posted by the OP is an H4. Nice.

Porsche classic sells them new @ $355 ea in case anyone needs a new set of H4's. It's actually a good price competitive even with our suppliers

I believe, if I've followed this thread correctly, there are at least two Porsche parts described as 'H4' -- one DOT approved and one European approved. If I'm mistaken please correct me.
Thanks to the tip above, I searched 928intl.com and found 928-631-101-03: H4 Euro headlight also at $355 each. Given the link in the previous post is to the Porsche Classic USA site, and given it points to a different part number, I wonder if that's the same item?
Regardless it appears the answer to my original question is that euro H4s are readily available at about $800 a pair all in.

Are you sure that's a euro H4? That a different part number than Mark has listed on his site for the H4 European spec.

The H4's have been available through Porsche dealers and our friendly vendors for some time. The correct part# is 928-631-101-03, that number is shown on the Porsche Classic website, in PET, and on 928 Intl's website. If you shop around you can find them for around $520 for the pair.
We've got them on our GT (with the Euro adjusters) and the S4, with 80/100w halogen bulbs. The GTS is stock. The difference is night and day, particularly if you live someplace where it gets dark and lonely.

That's a FANTASTIC deal, depending on what shape they're in. Even a few bucks less than I paid! Someone get on that! See?! This is the kind of deal I saw once in a blue moon that kept me going in my pursuit for H4 lenses at my price point. Sometimes you just get lucky!
Now... if only I could find those dang aero mirrors...

There are indeed two types of H4's that you should look out for:
1) Most commonly LHD versions which is what you want for the USA
and
2) RHD versions* which you don't.
Since the lights are asymmetric you cannot uses an RHD lamp in an LHD country (and V-V) and have a correct beam pattern. You cannot ever get an H4 of the wrong type to work acceptably well - there is no possible adjustment that can avoid blinding oncoming motorists while providing any worthwhile illumination of the road for you (e.g. H5's would actually be better for both parties concerned!).
* UK, Ireland, India, Pakistan, Bangladesh, Australia, New Zealand, Japan etc. in total about 75 (mostly small) countries - a minority of the world population, and a smaller minority of the Porsche buying population.
Note that Porsches in Japan are usually LHD cars with RHD headlamps. Importing these cars to a LHD country (often Canada) => lighting conversions often creating availability of RHD lamps in LDH countries (Canada/USA) - be careful of these! an expensive mistake.
Look for the correct part numbers as has been posted here.

Wow, these look cool.
I've been waiting for one of the "name brand" companies to come out with LED replacement bulbs. The wife's daily driver will be getting these ASAP if they make an H7 version.

Note that when you mount H4 lamps housings on a H5's aluminum yoke and don't change out the balljopint mount at the bottom of the yoke for the adjusting motor that is found on the European H4 yoke, the lamp mounts further forward, causing a bit of a misfit to the bucket cover. This is because the H5 yoke's lower mounting balljoint shaft is LONGER than the adjusting motor balljoint shaft. So, in order to get lens to aim properly, you need to move the top of the lamp further out, and the bucket no longer fits properly and must be distorted to use the attachment screws with the lens moved forward. Over all this is a minor problem, and some reaming of the frame slots may reduce the bucket misfit. Now, I see the new LED bulbs described here offer some aim adjustment. It's a bit odd to adjust the aim without moving the lens itself, but it might help regardless to get the cutoff low enough to prevent blinding oncoming drivers. Anyway, I have run H4s on my 89 for over 10 years, initially with halogens then HID and, for the last year, LEDs and they have been a big improvement over the DOT H5s and not hard to aim properly despite the slight misfit. The LED bulbs offer the advantages of much lower power consumption and simple plug-in replacement of stock bulbs, while HID requires rather installing wiring inside the wheel wells. Some recent LED offerings are now as bright and effective as as HID. I would not encourage anyone to go HID or LED in stock H5 lamps due to the diffuse DOT beam pattern that would throw too much light upward into oncoming drivers' eyes with these aftermarket high output lamps.
