Thanks for the in depth reply! This is what I was looking for. I am leaning toward the small lightheads against the headliner. As mentioned, they will hardly ever use them as they won't want to burn these cars, so flashback really shouldn't be a big concern.
I am also leaning toward the idea mentioned above with the dual color red/blue light replacing the guts of the third brake light.
For the
TLF and
HLF, please keep it simple wigwag patterns (I prefer the faster wigwag speeds). I cannot stand the flickering seizure patterns that some ppl use for the charger brake/tail lights (they look more like a toy car), instead of using the simple brake light wigwag. Another option to add some discreet lower level lighting is to replace the reverse lamps with blue/clear feniex cannon LAWs (steadyburn clear for reverse lights, flash blue when activated); unless a suspect walks right up point blank to the back of the vehicle (in which case there are other issues to worry about) nobody will ever notice those LAWs. I wouldn't recommend LAWs in the headlight housings, though, because the
HLF will drown them out, and the charger headlight reflector housing is not very conducive to using any type of
LAW or
HAW.
I know that you're probably leaning away from it, but if you wanted to add a slim pair of grill lights, 2 options to conceal them are tinting/smoking the lenses or (old school, poor man option) covering them with black stockings. The
SOS mpower fascias would work well here b/c of their small size, they're super thin, and they're very rugged. These are also a great product that you can use as a custom 3rd brake light option; I've seen a pair of them used on a 2017 charger (flash red/blue for warning, steadyburn red for braking), and it looked great.
Anything you add besides the
TLF/
HLF will be a plus; i remember seeing the NYPD anticrime units in older impalas when I was younger, and I couldn't believe that they were running code 3 in traffic with only a
HLF and
HAW strobes (nothing in front or rear windows)
As for controller/siren, a handheld siren will work well here; mount the remote control in the center console and mount the brain under the seat.
And, when in doubt, always remember the KISS method...keep it simple, stupid! ;-)
