full motor function plus safety

Anyone have any suggestions? I just created a simple DC motor operation. I'm not sure where or how i'd incorporate caps or even if i need to. Advice is welcomed. The motors have LED's to indicate when one motor is off or not working. I might place the LED's in between a Voltage Divider to prevent damage.

This application would burnout the transistors or just not work at all in a real life scenario. The motor current should be switched directly through relays OR through the collector and emitter pins of a BJT not the base. FETs are also an acceptable way to control a standard DC motor. As for LED indicators, these should be isolated from the motors in higher voltage applications or in lower voltage applications (less than or equal to 48 volts) driven through current limiting resistor. Caps are not needed unless AC is being used to drive the LED's.
