Does anyone know if this LED bulb will fit a '94 Kat Tail light as a direct replacement for the stock bulb?

1157 is the correct size. if you have a 600, you shouldn't have any problems with it fitting. if you have a 750 there might be an issue with the size of the head. i'm not sure that would fit the the opening. on the 600s, i believe you just unscrew a couple of bolts to get inside the tail light, but on the 750 you actually go from under the seat and through a hole to place the bulb.

Yup, you're right, my Kat600 just has 2 screws holding the tail-light cover.

you should be good to go then.
