@Chris I got the Recaros as part of the Pinzguaer build back in 2005. I forget the exact number. It was either $800 for 5 or $800 each. I saved two of them from the Pinz as part of the deal to trade for the Jeep.
@XISophos If I was less of an archivist I might have more time to wrench, wheel, and ride(MTB). I should seek professional help.
@glwood & @Chris This LED set did not require a new relay (at lest that I have noticed). I think I remember reading that they did not require any other changes. Not my field, but I believe that they have built in resistance. Typically LED lights have way less resistance than typical incandescent. The increased "flow" causes the relay to trip/repeat faster accordingly. In another career we had to install incandescent lights in closets on the same circuit those "new fangled LED lights" in restaurants. When the restaurant dimmed the lights they all started flickering... it was lack of resistance thing that was solved by the added resistance of the incandescent lights. I assume that the auto industry went thru the same learning curve. I do know that these were sylvan brand that I got at Auto Zone.
If those work without a new relay, great! LED replacement tail light kits usually include a new relay, otherwise the tail lights blink too rapidly.
