This is really cool. I may have to steal this idea next year.
Be careful with this, having red lights on the front of your truck is illegal for many states. Some also include blue lights. In RI it can be up to $1000 "impersonation of an emergency vehicle" fine. Here it is ok if parked or in a parade, but not on public streets. Every state is different. Some say amber only, some have lumen restrictions, some are good with anything other than flashing. Do your homework before driving.
I am even restricted to the total amount of light that the truck can emit from a certain distance. It's crazy. In my city I would need a permit to even use anything other than amber marker lights even if I am parked. Google "emergency vehicle restrictions, city, county/parish, state for more information than you will ever want.
