First off mine didn’t come with instructions so I had to figure it out took a little while to get it started but once I did it wasn’t to bad . On mine you had to run a few extra wires for the day time running lights to a fuse box, and to the battery I didn’t realize that until I got them . I installed them on my 2016 Tacoma they changed the look so much I get compliments on how it looks like daily. I was surprised on how bright they are a huge difference then the stock ones . You won’t be disappointed!!!!
