The problem is at the connections. For two contact LEDs most of the manufacturers use a resistor to dim the light on tail light mode while in a regular bulb two different filaments are used.
For that reason if we don't use a diode at the brake light end some of the positive voltage (here 7-8v) is found at the brake light end as if we apply brake.
