DLC survivor perk idea : Backflash

So recently I've been playing Dying Light (Not the multiplayer) and it was pretty fun. One of the skills I saw that I like the most was Backlash which basically allows you to use your secondary while looking behind yourself and running (One of those secondaries is a UV flashlight. You see where I'm going with this?).

Now I didn't use it so often since I rarely get chased by Volatiles to the point that I need to look behind myself repeatedly but I thought it would be an interesting mechanic to put in DbD since it's third person and you can adjust where your camera is facing.

Backflash

Backflash guarantees a Sport Flashlight in your first chest search

While running, you may aim the flashlight beam behind yourself. You do not slow down while using the flashlight

Increases flashlight efficiency by 15%/20%/25%

The problem with flashlights is that you lose lots of momentum using it. With this, flashlights can be used to annoy the killer during chase, forcing them to look up and down and allowing you to get away or something.
