Coach B’s (@everythingbrooklyn) TikTok clip shows herself pulling down a tab on the bottom middle of her vehicle’s rearview mirror.
Pulling this tab towards the back of your car activates daytime driving mode, which provides a more transparent perspective.
Pushing the tab toward your vehicle’s front initiates nighttime driving mode, where the reflection’s dimmer.
This dimmed reflection reduces glare from headlights following your car.

A vehicle’s rearview mirror is a wedge of glass with one side thicker than the other.
Flipping the rearview mirror’s bottom tab results in the wedge moving, according to Your Mechanic.
This movement alters how light enters your car’s rearview mirror and reflects.
Daytime driving mode reflects light and images through the mirror’s back surface, whereas the front is responsible for the nighttime option.

The front section of the wedge is the nighttime driving configuration’s foundation.
Nighttime driving mode forces light and images to go through the wedge’s backside before hitting the front and reflecting back to you, resulting in dimmer headlight reflections from following motorists.
One viewer commented on Coach B’s TikTok: “I didn’t know about this either until a few weeks ago, and my life has been changed ever since.”
A second TikTok account wrote: “Just reminded me that I have this.”
Other viewers were shocked at how many people didn’t know about this trick beforehand.
A third TikTok user commented: “Read your manuals, guys.”
Another viewer said: “Y’all didn’t know? I suffer from sensitivity from lights.”
