You need to completely remove the lamp and front chrome rings from the lights. Then the visors fit into the front rings. I trimmed the little tabs on mine off with some side cutters. You may have to VERY carefully bend them a pubimeter to get them in. Especially the big one, it is a very tight fit. Then, using all four of your hands, put them back together and tighten them up. 3 hands definetly makes it easier as holding the stupid rings/spring clips and visor correctly aligned is an exercise in patience.
The good news is that once they're on, they are never coming off, or ever need to come off either.
The big one for the headlight is the most fun by the way. Buy lots of beer, it's a sixer at least. A lot of work for a little job due to the fitments.
