Check out these lights I'm going to use from Technostalgia. They are high quality, properly fit the fenders, and a big improvement over bulbs.
1940 Ford complete taillight assembly including chrome plated bezels, buckets, lenses, and body seal. Includes two light assemblies with LED arrays, electrical harnesses, connectors, and attaching hardware. Our ’40 lights actually fit the fender. Lights designed to shine at towards the rear of the car, not at the sky.
