Code 3 Force 4 XL Lightbars

The lightbars used on the original Ecto-1 and Ecto-1a were Code 3 Force 4 XL lightbars. The Ecto-1 had all blue domes, or "outboard lenses" with a chrome strip across the top, and was the 48" long version with the chrome speaker grill in the center. These had single rotators with the diamond mirror in the center of each side. The Ecto-1a had the same make and model, but with clear domes, not blue, also with the chrome strip across the top. Instead of the speaker grill in the center there was another clear dome, also with single rotators.
