I installed these on a 2003 EZGO shuttle. The cart came with the factory light bar and turn signals but I never really liked the look. These lights come with the two lights in housings, a paper cutting template and screws for mounting. The lights themselves have two plastic plugs on the end of the wires, and as I suspected would probably be the case, the plugs did not match up with my wiring harness. So I did some testing, a little trial and error to figure out what wire does what, both on the cart and the lights. I took a deep breath and cut the connectors off both the lights and my cart and replaced them with heat shrink marine connectors. Everything works great, including the turn signals, even though I did not use two of the wires coming off the new lights. I taped the ends and zip tied them out of the way. I love the new look and they are much brighter than before. Shipping was super fast, great seller and great product!
