Geez, haven't seen those in many years. Is that from your old stock, Dave? Had those on my car for a short while right when I built it in '79. Painted the buckets flat black, too. Then, saw the light (pun intent) and from then on, ran some sort of VW and/or Porsche Euro spec lighting on every Volkswagen I owned.
Cool that you're offering the glass ones. I had the cheap plastic wannabe ones. HAHA!!
Nah, Fred-- these are new.
My driving force was to highlight the NOS Marchal Amplilux two bulb lights I've had for so long.
I figured the flat glass would do the trick... and I think it did.
