Cree LED H4 Headlamps
I just fitted and adjusted my new CREE LED H4 headlamp bulbs from 'Woodypeck' in the UK and they are fantastic.
They pass UK MOT which is the seller for me.

All the LED H4's I have seen seem to extend much further back than standard H4's, which would interfere with the the 928s "protective cap". Do you just omit the cap in this case, or am I missing something?

Seems like a lot of kits have "ballasts" ... are the ballasts required? (any pic of the Cree kit ones?)
Also - anyone have a quick primer on bulb/lens differences by year? I know I've got the larger lenses, and online resources say it's a 9004 off the shelf replacement bulb, but as I look at aftermarket stuff "for the 928" it gets confusing as to which 928s they fit.

That site has LED fog light bulbs too "custom made for the 928." Would that work for US cars though, or Euros only?

Any excuse to get the band together and a few cases of beer.
Due to a few discrepancies I found on that site, I think it would be best to wait until Roger gets this sorted out.
There is a lot of garbage out there in the LED / HID market.

Hi-power LED chips need cooling, this is usually done by mounting the chips to an aluminum substrate which extends out the back to a fan assembly, or sometimes just a bunch of big fins.
So that rear cap (#3) definitely does not fit. The problem is that cap is what seals moisture out of the reflector housing-- the H4 bulb (#2) mounting is not even close to watertight. And it does get very wet inside the headlight housings with rain and road spray.
Here's the pic of the LED lamp assembly from the Woodypeck website:

These are what I was looking at, same but newer design w/ smaller heat sink.
From what I've seen some of the olde units even have fans
http://www.vleds.com/headlights.html
EDIT: just noticed the "close out" pricing, maybe newer ones coming out?
The ones in the OP (for 928's) have a greater LUMEM output too, 5600 vs 3000
