Review on Socket Adapter Reverse Multi Purpose Connector by Chris Reddick

Inserting a lightbulb proved almost impossible, required a lot of pressure and then still wouldn't "snap" into the sockets. If you try to use force, it will most likely break the glass bulb and cause injury. Second, the gasket is also too thick, making it difficult to fit into the taillight bracket and requiring modification. The internal contact points in the socket are sloped rather than flat, making it difficult for the lamps to seat properly. I managed to get them to work by flattening the contact points, installing a thinner o-ring and the contact points on the bulbs and still had a lot of trouble installing them.
