>Muh light speed is constant
Okay if that's true then why does my flash light have a finite reach?

It isn't very bright, and neither are you.

Because it's just invisible to you.

Actual answer: your light photons gradually loose energy and change color before becoming undetectable infared waves and then radio waves. When light """slows""" it just changes frequency from a high frequency to a lower frequency. Additional frequency can be added through heat, magnetism or gravity. These affects are usually not noticeable at our level but are more profound at the subatomic scale.

this doesn't happen on the few dozen meters that a flashlight can reach

The reason is that human senses are shit. The light carries on but the diffuse reflection intensity falls below the threshold for human perception.
