With encapsulant potting for total circuit board protection and hermetic lens-to-housing seal, Our SuperNova 2-1/2" LED Clearance Marker Lights use the same UBS double-seal pigtails as incandescent versions for a quick Plug-and-Go Retrofit. The tin-plated, solid-brass terminals are sealed to housing, to resist corrosion and eliminate failure causing leak paths. Genuine Grote product.
