The problem is in the vehicle or trailer wiring. Something is shorting out the power wire for the Brake Light and putting power on that circuit at all times.
I would trace the wiring of your 4-way back looking for corrosion or cut or exposed wire that could be causing the short and fix as necessary. This light should only come on with the brakes or the right turn signal comes on.
I have included a FAQ on troubleshooting your trailer wiring for you to check out.
