550 Spyder complete running lights kit, two front turn signals (clear), and two rear tail light (red) lights with light sockets, rubber seals, and light bulbs.  Lenses snap fit into the bezel for a secure (no silicone goop) fit.  Between the lens and the bezel is a thin rubber O-ring (see pictures) to add additional weather-sealing characteristics.  The bezel and lens then turn and lock into the base and rubber body gasket for a secure, weather-resistant assembly. This set is much better than the similar light set available that required gluing the lenses into the bezels with silicone.  That is why we decided to do these right and invested in the tooling required and produced a proper light set.
