I went to the Tri-State Engine abd Tractor swap meet last month, and came across these Grote tail lights
They are like the ones used on the early Cub Cadets however the markings are a bit different.
On the one on the right, the light is marked Grote, the lens is marked Grotelite 218, Patents Pending.
On the one on the Left the light is marked Grote 218, SAE-S-T, the lensis marked Grotelite 215-218
Both have the same type mounting as used on the Cub Cadet, but it is longer.
I compared them to the one on my 100, and the light on it is marked Grote 218 SAE-S-T, the lens on it is marked Grote 215-218, SAE-ST-1
The 3 lights are basically the same but the lens, although interchangable, are all different insofar as the reflector in the lens. These lights, like the "Original" head lights, were used on different pices of equipment such as some of the Farmall Cubs and offset Cub Lo-Boys, some of the numbered Lo-Boys etc., but at the whopping sum of $2 each, these will find their way to a Cub Cadet sooner or later. Wish the guy had more of them........
