[Klint]

again I have been running Red and blue for about 9 years now..
I respond to ALOT of wrecks on major high ways where I will be the first on scene and people really ignore Red lights so when you're trying to slow traffic now and move traffic over or stop them you need red / blue and also I have amber 2 amber strobes in the back also

Back is setup like this

[BLUE | AMBER] [ RED | BLUE ] [Amber | RED ]
