Make sure all the bulbs are in correctly, they go right in if the posts are positioned properly. I had problems when I got mine but once I did it right everything works as it should.
I used a pair of cheap cloth gloves when I did a couple vehicles. They slid easily on the aluminum tape backer and protected my hands from the heat. Worked great for getting in tight spots,
While messing with my visors I realized I had the plug up there for at least a compass mirror so I plugged that in. I didnt see wires for the visor lights
