Depends on the which truck. The 2 newer trucks have Red and White strobes. The brush trucks vary from blue to amber to what looks like a purplish pink. The tanker has blue strobes on top and red and blue wig wag spot lights in the back. But we can have blue red white amber and even green. I have x6 dual 8 led lights on my personal vehicle that are red and white.
My department's trucks are red/white with a yellow traffic advisor on the rear. For our pov's we use red/white
We run Red and white with one amber on the back of the apparatus. Our POV's are red and white also and a few amber if we want.
Our apparatus have red/clear light bars and red flashers/strobes on the sides. Two of our older trucks also have an amber beacon on the rear. No lights on POV's in our department.
