Why were six taillights a thing on a Corvette? This was a tie-in to Chevy's 1958-65 full-size cars (excluding the 1959 model year with its squinty teardrop – shaped taillights). If you're familiar with classic Chevrolets, then you know that the 1958 Delray and the 1959-65 Biscaynes were no-frills affairs, with few if any options. The Bel-Air was a bit cushier, but still a "budget" vehicle. These models had four taillights. Meanwhile, Chevy's top-drawer Impala had six taillights. Introduced in 1965, the new flagship Caprice also had six taillights. This arrangement briefly disappeared in the mid-'60s but returned on the 1968 full-size Chevy with the "horseshoe" taillights.

Therefore, the mentality of the extra lights on the Corvette was to add panache to the vehicle and make it look more upscale, a la the Impala. All this being written, there have been various other production Chevys with only four taillights. How would they look if given the same treatment? Let's see a few.

Note: As far as I know, none of these fantasy vehicles exists in reality. It's just me, horsing around with photo software.
