Best Quality Reproduction Back-Up Lens Gasket Officially Licensed GM Restoration Part Original Style Correct Thick Die-Cut Gray Rubber Gray Rubber Keeps The Reflector From Appearing Dark Sold As A Pair For Rally Sport Cars Some of the reproduction 1969 Camaro backup light housing assemblies come with a black gasket between the housing and the lens. This causes the reflector to reflect black, making the lens appear very dark. Critical for a proper weather-proff seal, your Camaro's park light gaskets keep water, mud, and other debris from entering your back up light housing, which could cause rust, grime build-up, and electrical problems. These gaskets will keep your lenses bright just like they were when your Camaro rolled off of the assembly line. With correct thick die cut gray rubber, this pair of back-up light to housing gaskets will keep the reflector from appearing dark on your Rally Sport F-Body.
