In 1977, Buick came out with the special edition Skyhawk, named the Nighthawk. The Nighthawk is essentially an appearance package only, featuring the same standard features of the Skyhawk. The similarities end with the exterior look of thecar. The Nighthawk starts out with coal-black paint and gold colour-keyed wheel covers. The truly unique feature that completed the Nighthawk is the special reflective striping that only becomes visible at night. They start on the side of the front facia going along the side of the car right to the rear hatchback and across the back of the car with the trademark Buick hawk bird on the front fenders and the rear hatch and 'night hawk' in script on the front of the doors and also on the rear hatch. There is also a wide gold band on the 'hump' of the hood as well as some pin striping along the side of the hood 'hump'. As Buick says, they are virtually invisible during the day but "shine like the moon" with a gold tint when they are hit with light. The Nighthawk decor package was given an RPO Code of WH6 and was only available for the 1977 model year.
Many Thanks to Patrick Polk for these pics of his Mother-in-Law's beautiful '77 Buick Night Hawk. The pictures with the gold striping that seems to 'glow' (2 bottom left pics) were taken with a flash to give you an idea of what they would look like at night, in the light.
