The on/off switch does not work properly: it turns on with difficulty and turns off on its own while in motion. Additionally, it is quite large in size, covering the entire back part of the grill.

Very good choice for a rack light! It is quite large (covers the entire part of the rack where it will be installed) it just doesn't have light modes, for example, to flash, it only turns on and off from a button at the bottom. It included the batteries, however, it did not contain the screws needed to attach it to the rack.
