Hah, yeah I've done the 0 mph tip over a couple of times. Once in my garage just moving the bike around. Both times the turn signal hit the ground and broke the fairing. The luggage was not mounted either time. I keep the luggage mounted most of the time just to make it easier to pick the bike up if it goes down.
Anyhow, I replaced the turn signals with R&G micro LED signals. They don't stick out as far, so they won't hit the ground in any kind of fall. Here's a link to my installation of them. https://www.kawasakiversys.com/forum...n-signals.html
It isn't a difficult job. R&G now also sells an adapter plate for a cheap price, so I would get that rather than make my own today.
Crash bars typically don't protect the front turn signals, because the signals stick out too far. They break the line between the end of the handlebars and the folded up footpeg. Anything that crosses that plane will hit the ground in a tip over.
There are 2 versions of crash bars. Most only wrap the upper plastics. A few designs protect the lower engine as well as the upper areas. I opted for protecting the lower engine because I sometimes go off road. I don't want the engine casing damaged by an uneven rock surface if I drop the bike.
Sliders will not protect the factory front turn signals, and neither will crash bars. Frame sliders should protect the main parts of the engine area if you slide or drop on a smooth surface. If you drop the bike on a softer surface like grass, the sliders may not really do much at all for you. Crash bars would do a better job, though I've gone down in mushy grass and the whole side of the bike was muddy. But nothing broke off, so the bars did help probably.
From what you've described, I would just replace the front turn signals with a micro sized LED set. The LED are really bright. You'll need a cheap adapter that plugs into the harness to convert to the LED so the flash rate doesn't change. Read my link above, it is super simple and cheap.
Sliders or crash bars would provide protection if you go down above idle speed. That's a different mission than protecting the turn signals and the expensive plastic they are mounted to. Now we'd be considering how good is your insurance, how do you like the appearance of crash bars, etc.
