This Avantco 17814224 LED light plug is a direct replacement for the one that came with select GDC, SS-1R-G-HC, SS-2R-G-HC, A-23R-G-HC, and A-49R-G-HC Avantco units. It is designed for use with the LED light inside the unit (sold separately). Your unit's lighting makes it easy to see the interior contents, so be sure to replace a broken part promptly.
