When you add a brush kit to a Flex-21, and it’s in the raised position, it blocks the light when you are making a turn.
The workaround was to make a new bracket for one light, and mount it under the brush. Now you have pretty good light no matter what. 
First time I flipped one of these back to adjust it, it kept right on going. Trailer wasn’t quite like the one we had for our 1000’s.
So we came up with this helper on the spur of the mention and it’s been here since.
A couple feet of chain and a couple of pieces of old roller shaft.
