age dashboard. The steering wheel was squared-off at top and bottom, designed for better legroom and view through the windshield in the straight-ahead position. Dashboard lighting was electroluminescent, which used no incandescent lamps: electricity running through a five-layer laminate caused the phosphorescent ceramic layer to glow in the dark. Chrysler called it "Panelescent", and it was shared on some Chrysler models. The effect was eerie and surprisingly modern, with its glowing blue-green face and bright red needles. The 1960-63 models were also united by a distinctive side trim that started above the headlights and that ran at a slight downward angle almost to the end of the rear fender (except in 1963 when it would actually wrap all the way around the rear of the car) that was undercut by a slight indent in the sides from the front until just before the rear wheel housing. A significant change in the car's proportions had occurred between the 1959 and 1960 model years. Although, at 226.3 inches, the 1960 Imperials were exactly the same length as the previous year, the whole body had been shifted forward, with a 2.1 inch reduction in the rear overhang, and a corresponding increase at the front. 1960 (Series PY1-L,M,H) The 1960 Imperial adopted wildly exaggerated styling, featuring front fascia with a swooping bumper, gaping mesh grille, giant chrome eagle, and hooded quad headlights, and tall rear fins. Soaring fins had bullet-style tail lamps at the peak of the fin, with a chrome ring surrounding it. The grille and bumper on the front of the 1960 used large pieces of heavy chrome, and the 'furrowed brows' of the fenders over the double sets of headlights gave the car a ponderous look. In common with most other 1960 Chrysler products, the Imperial featured the new "High-Tower" seat with the driver-side back individually contoured and raised above of the rest of the front seat for increased driver comfort and shoulder support. This would last through the 1962 model year. Also for 1960, Imperial changed back to 15-inch wheels from the 14-inch wheels that had been standard since the 1957 model. Imperial LeBarons now featured a distinctive smaller "formal rear window" for greater rear-seat privacy. Sales increased to 17,719. Imperial again finished ahead of Lincoln, but never did so again. While the rest of Chrysler's lineup adopted unibody construction, Imperial retained its body on frame construction. 1961 (Series RY1-L,M,H)
