The clips last a very long time, if they are somewhere they won't get bumped or snagged, and don't bear the full brunt of the weight of the Maglite. I kept a 3-cell mounted in a vertical position in the rear corner of my standard cab pickup, Maglite butt on the floor. Over 20yrs. It was easy to reach there, but protected.
I just recently stripped them out of that pickup (been parked in the driveway for a year, rarely used since I got my Sub, I should sell it) and transferred things to my Sub. I put the mounts on the side of the center console, down low between it and the driver seat. The bezel of the flashlight sits below and behind my knee when driving, out of the way but immediately to hand.
The other side of the console, I went ahead and mounted one of those seatbelt cutter / window breaker emergency tools. For the passenger mostly, I always have a serrated folding knife in my pocket.
The console itself, I'm use a couple small zippered pouches, one for minor first aid and various over the counter meds, the other for various power and electronics support items, USB cords, memory cards etc.
In front of that, I build a custom middle console to replace the factory piece, which will house both CB and HAM radios.

And lastly a dash mount for a 7" android tablet.

I'm also adding USB outlets to the overhead console for my phone and a dashcam, and inside the center console to keep a bluetooth earpiece and the tablet charged when stored.
A larger first aid kit is in a vehicle cubby in the rear cargo area. medium size fire extinguisher is mounted just inside the rear hatch. When I get my platform / drawers built, the left drawer will be full of off-road and roadside emergency gear. I'm using a plastic footlocker tote now. And that's all under the factory cargo area shade. Basically there isn't much to see when looking in the window. All the electronics are / will be out of sight.
