A little info on it... designed by W.C. James, who was head of the special effects department at Twentieth Century Pictures Studio. The truck was illuminated with 600 feet of neon tubing. Blue neon was used for the outline and side lettering. Gold neon for the radiator shell. Red neon for the cab lettering and the Red Lion and "Roar ..." slogan at the rear. Fifteen thousand volts was used to light it. Power was created by four generators mounted on the left side of the engine and driven from the fan belt.
