I recently bought a 1981 kawasaki 440 ltd d1 and realized a few days later that the hand brake wasn´t lighting up my brake light. Being my first bike I didn´t realize there wasn´t a front brake switch and no wires, just the hand lever and brake line. I´ve been looking online for a replacement but haven´t found anything. Anyone know where I can find one or how to fix this issue another way? I would appreciate any help.
