Hi Dutch T-Bird:
Visited your country back in 91. Had a great time, and would love to go back sometime again.
With regard to the Hewlett-Packard LED/Reflector units, they were custom made for the T-Birds, and are no longer available, unless you buy "new" ones from Ford. Even the individual LED's are not a stock design. That part number in the Tech Article is a valid number, but you cannot order them.
If you can find a working set from a junkyard (I know - Holland), or have someone here ship you a couple working used ones, there aren't too many other choices left.
I suppose you could cut the back of them open, and try to see what went wrong on the circuit board to make the LED's go out.
