They look nice, Lucas did a spot / foglamp version that looked very similar with a sort of chrome nipple in the middle of the lens, but they are quite rare now
Cheers Jon, it's all about the nipples
Apparently they're even more pronounced in cold waether
These fog lights are Marchal 670/680 replicas, not cheap but still French made and excellent quality, often used in period on Ferrari 250s, Maserati 3500s and Facel Vegas but most commonly seen or Porsche 356s.
The secret to the mystical golden glow is clear lenses covering the correct Marchal yellow globe bulb.
The effect is rather beguiling, romatic, nay enchanting even
The mystical golden glow should work well against Monty's Sport Green paint and will tie in nicely with the brass and gold details I've been adding.
