I represent LED Door Sills. For door sill LED illumination, think about when you want the plates to light up before arranging installation. Our wired setup is intended to connect to a vehicle circuit activated when the door opens. It requires wiring work rather than simply attaching the plates and switching them on. Product options are at https://leddoorsills.com/. If you are using an installer, discuss the connection and wire routing along with the threshold measurements.
