Basically, aftermarket parts come with instructions only up to the point of getting them to work.
Future removal and convenience aside, as long as it functions, that’s fine.
But
I think everyone wishes it could be mounted a little differently to be easier to use, easier to see, easier to remove.
If you want to keep the same bike for a long time, you should think it through carefully before installing anything.

If you start by installing parts in easy spots, you’ll run out of room later. ( ゚Д゚)
The handlebar area is especially like that.
With a bar-type handlebar, the area around the handlebar clamp is an easy spot to install things.
As the available mounting spots shrink and you start adding handlebar braces for temporary expansion, there’s no stopping.
If you pause and really think about where parts should be mounted, each installation becomes more enjoyable.

Mount it on the right? Mount it on the left?
When every action has meaning, things become deeper and more enjoyable.
If someone asks “Why did you put it on the left?” and you answer “Just because,” that’s a bit sad. ( ゚Д゚)
It might work the first or second time, but by the fifth or sixth time, it won’t.
I always try to be careful not to become a running Don Quixote.
Many people say they can’t do that kind of modification.
If I were asked to do the same thing in my driveway, I couldn’t.
I’m not confident I could even swap out a lever properly. (´∀`*) Hehe
Before you can or can’t, know or don’t know, you first need equipment.
The world is full of phrases like “easily do ○○.”
Is it the task that’s easy, or is it the thinking in your head? Without real care, you’ll definitely end up with a dent.
Injuries and lunch boxes are your own responsibility. In a world so full of information, it’s really difficult.
