Sounds like it would look great. My two cents-
It will look "more professional" if you hide the strobe lights in the headlights, brakelights, etc, but if mobility is important, I would recommend items such as the following:

Wheelen Slimlighter LED. light, suction cups to all the windows, draws less than one amp. Something like this can be suction-cuped to both the windshield as well as the rear window.

Tomar dual strobe. This should also suction cup to the window surfaces, but will be heavier. Draws about 2 amps.

Mini strobe light bar for the roof. If you want to be seen in all directions, this is a cheaper, easier way to do it. The magnets have anti-scratch pads on them so you don't scratch the roof. This is what I have on my roof.
If you do decide to drill and mount strobe bulbs, realize that they must be linked to a strobe-pack. This recieves the power from the battery and then divides it to the strobe heads (bulbs). High watts, brighter lights. Remember to divide the total wattage of the strobe power pack by the number of lights. i.e. 60 watt power pack, 4 bulbs = 15 watts per bulb- not too bright.
Strobes that come with cigarette lighter plugs have internal power suppllies and don't need a seperate power pack- i.e. the Tomar roof light and windshield lights above.
Most LEDs are clear when they are off (most come with clear lenses- the individual bulbs are what are colored)- kinda nice if you want subtly when they are off. - In my photos, the small lights mounted under the PIAAs and the Slimlighter mounted on the inside of the windshield, high up by the passenger sun visor, are LEDs.
If you do decide to permanently mount hidden strobes, I installed them into the back brake lights fairly easily. Let me know and I will explain how. There was room to put them into the back up lights as well. There is probably space to get them into the headlights, but it would be tight. No room up in the fog lights. But, probably enough room in the DRLs. Otherwise, you can always mount LEDs light I did on the front- they are clear when off, look like accessory fog or driving lights.
Hopefully this helps. Remember, wherever you are, you always need permits for blue, clear and red lights. Most state even require permits for amber lights, but I've never heard of a cop actually asking to see an amber light permit.
If you only use the lights for escort purposes, you could probably get away with amber and clear without problem. And they look nice for show too
If anyone wants photos/explinations on how I mounted these lights, let me know and I will post.
