You might classify these under "Other vintage lamps". Lucas 4FT and 4LR fog lamp and driving lamp normally fitted to earlier MGs (TD and TF), Morgans, and Triumphs. They are an inch smaller in diameter and look more "retro" with the built-in chrome hoods. They're also very hard to find since no reproductions are currently made, and they were originally available in far fewer numbers. You may realize after you install them that they are perhaps more for show than for light.
