These lights work great. These just come with the housing and the green LEDs around the edge. No bulb but easy to find. The LED lights have two wires on each side (total 4 per light). You simply splice these to your parking lights. Depending on what you want, you can have these turn on with parking lights and stay solid or connect to blinkers and they will stay solid all the time until you turn on blinker.Love them.. Worked great on my 71' VW
