It provides a long-lasting, low-power way to mark the vehicle's width and presence, meeting FMVSS 108 standards. The sealed, potted electronics and corrosion-resistant brass terminals make it far more reliable than incandescent bulbs, especially in wet or road-salt environments. It's a direct replacement for many factory and aftermarket 2.5-inch round marker lights and uses the same PL-10 pigtail as older incandescent versions for a quick Plug-and-Go retrofit.
