There were parts that were missing in the lights, but, I called my relative, who is an electrician and he replaced the parts missing and hooked it all up for me; so I can say I am happy he helped because my husband would have been electrocuted if he proceeded to do it.  Wires were in the wrong place.  Came from the factory that way.  I will still buy from Wayfair, but, I am not impressed with this product.  I do have them up and they are working fine, so far.
