The brake light is actuated by either the switch on the master cylinder or the rear pedal switch which is located on the frame and uses a spring attached to the pedal. That one is adjustable whereas the front one isn't. You can jumper the 2 wires on the front one to keep the light on for testing.
PM sent for the Honda FSM and color wiring diagram
Be aware that with LED front turn signals there is the need for diodes to be added to the indicator bulb circuit. Personally I like the stock units because they're big, bright and easy to see.
