Bill,
Very nice car. Is that the original color? Looks like Medium Poly Blue same as mine except mine has been fading for 60 years.
The tail lights are for a car that doesn't have backup lights. The center should be white if it had backup lights. Mine has the opposite problem, backup lenses but no backup lights. I bought the only set I could find while driving mine after one broke.
Again nice car, hope you enjoy it.
