I did a quick install of my 2X2 spots just to check them out. Solid construction and excellent light output.
I used the harness from my old Hella driving lights. I have a Slee Aux Light harness to be used when doing the final install. I already have the Slee Headlight harness upgrade already.
Those look great. I was going to get a 21 but now I wonder if 2 little ones will be enough for general night driving
