There are three smart lighting placements; on either side, in the center above the door or spread all along the top. The best option is up to preference and fixture size. For most single door garage, one lighting fixture installed in the middle but above all moving parts should offer sufficient illumination. For double door garages, it is smart to place a unit on either side. For even better visibility, consider a combination. For example, one central and two sidewall fixture, but keep the designs the same for cohesion.
Also, remember to install the lights in spots that won’t interfere with other garage door functions. Don’t let the fixture or the brightness block the sensor for opening the door.
