(Flashlight bug) My flashlight has a line on my screen but I've had this since launch

This is a known issue. You can lower you FOV to 74 or below to eliminate this effect.

what about the color of the flashlights, I’ve picked up at least 1 of every color of the flashlight

what about some new skin colors for the flashlight

The flashlights are no useable item like binoculars, nor a useable apparell like the gas masks.

They are just a key to a feature.

But, if they would ever change something at the flashlights, I would love to see some other colors of light for better visual communication with a team.
