Awww man! I was hoping that I was still a 10-8 brinks truck and that you'd "accidentally" happen to provide your fellow ELBers some details about it & it's future schedule!!!
I would recommend against the rocker panel lights; I think that they won't add much during the daytime. To be honest, I'd set it up like a basic ambo...
--2 large grill lights, colored lenses
--2 intersection lights, colored lenses
--2 large surface mounts per side (upper box), colored lenses
--2 scene lights per side (upper box next to surface mounts)
--4 large surface mounts to rear (2 upper, 2 lower), colored lenses. No TA needed, unless the IC is an idiot that would dedicate his APC to perimeter traffic control (instead of a road/patrol unit)
--HLF. Luckily for you, FL. & Intl. trucks are so common as commercial chassis fire/rescue vehicles that it won't be hard to get one that's compatible
If you don't have the defender get, I'd go with a less expensive lightbar that is depopulated to the rear (which nobody will see); otherwise, I u have it already, I'd look to sell the rear mods as a few more bucks in the piggy bank. Another alternative to a cheaper LED bar is going with an edge; I don't know of many SWAT/SRT trucks that roll code 3 frequently, do I don't think you'd have to worry about replacing strobes much, and the most important lights on a truck like this (IMHO) are the perimeter lights b/c they'll see the grill lights a lot sooner than they'll see a lightbar.
As far as tools you'll need for the install, you'll need some hurst cutters, an oxyacetylene torch, a sledge hammer, some C4, & a jackhammer for mounting the roof lightbar. Not worries though...all of these tools can be found in aisle 18 of your local Lowes ;-)
