I'm almost certain that its a custom color as for Big Frank's wife picked the color. I know the city was having the dealer paint it before delivery thus costing so much. That's when we went to white in 1988.
I PULLED THE FUSE IN THE LINE FOR THE LIGHT BAR AND ALSO PULLED THE BATTERY CABLE...... I HAD THE BAR APART AND NOTHING WAS CRIMPED..... THESE LIGHT FLASH AS SOON AS POWER IS PUT TO THE LIGHT. THEN AFTER I CUT POWER THEY STAY OFF UNTIL SOMETHING IS ACTIVATED AGAIN.
