You don’t need a toolbox for this. Maybe a screwdriver if the sensors are loose. And maybe a ladder if they’re mounted high.
But mostly, you need patience and a willingness to crouch down and squint at a tiny light. That’s the real work.
Pro tip: use your phone’s camera. Point it at the sensor. Sometimes your eye can’t see the alignment, but the camera shows if the lights are even. Fancy, huh?
