It is important to know where to get replacement car parts. For a 1965 International D1100 the brake lights usually have to be ordered from a local auto part store.
you forgot to plug in the brake fluid sensor.
Kind of vague on the question. If all other rear lights work....tail and turn signals, I'd say it's the brake light switch. You'll find it mounted under the dash, just behind the brake pedal. As you press the brake the switch "opens" to send the signal to the brake lights. These replacement switches are really inexpensive and available at any parts store.
1. Check fuses. Should be near parking brake pedal. 2. If it's not a fuse, check to see if the bulb sockets have vibrated loose.
