Don't get me started on shoot-me-first lights....
I don't subscribe to the Swiss Army Knife builds.
But at the end of the day, it's your opinion that matters and not anyone else's.
Agreed on the light.
Everyone thinks they need to have a light and they seem to think it always has to be on the gun, ignoring the whole modular capability issue¿
I even have a light. It's almost always detached. It only goes on the rifle if I am using the rifle at night in circumstances where I'd potentially need a light. Those situations are rare. I'm no longer an LEO and don't go into dark places looking for bad guys. The most likely scenario is a home invasion where I am also not absolutely sure of the location of the other members of the household and where someone has obviously broken in.
Using the light even then is a trade off. In my home at night, my eyes will be better light adapted than an intruder if he's been using a light, and I know my home intimately and can navigate it in the dark. Those are big advantages that you give up when you use a light. Consequently your use of a light has to have a very clearly defined purpose in that situation.
For example, your daughter has an idiot boyfriend who may have decided sneaking in at night was a good idea. In that case you may or may not decide to shoot him. You might decide that taking him down and having him arrested and hauled off by the police is a better option. A light may be required to make the positive ID either way and or to confirm it's the idiot boyfriend and not an armed intruder.
In either case, the light on my self defense rifle also has a momentary switch so that I can briefly flash the target for positive ID just before I shoot it - or not.
It's also mounted without a remote switch, etc and instead is positioned on the forearm so that the momentary switch on the back end can be pressed with the thumb of my support hand. Keep it simple.

Someone above also made a comment on self defense weapons not needing batteries and that's spot on.
The above braced pistol is my truck gun and is intended for use out to 200 yards. The Burris 332 works very well for that as the magnification is low enough to let me shoot close quarters with both eyes open with the big donut element of the reticle visible in my dominant eye. The finer elements in the reticle make precise hold points for longer range work.
The reticle in the 332 is illuminated but doesn't have to be as it's a prism scope with the reticle built in.
