Having status LED's on the board is nice, but they're next to useless when the board is mounted in the stack or under a cover. The next rev of the board IMO should be designed so that these LED's can be mounted remotely. A simple pin header could either be jumpered to use the on-board LEDs or used as a connector for remote LEDs. At a minimum, the user needs to see the arm/disarm LED and the GPS lock LED.
Thoughts?

As a bulder of a HK HAL frame based quad with APM Mega 2.5, I have a problem of not easily being able to observe the GPS locked or ARM/DISARMED leds when flying.
Having no clue how to do any adru code changes, it is way out of my capability to make code changes to enable Leds as R_Lefebvre suggested.
Is there no easy way to connect 2 or 3 LEDS to the 2.5 hardware?
Thanks for patience. I have searched threads for hours and this is closest one to my issue/desire that I found.
Here's what you need to know in the code. Long story short, you can plug small external LED's into the board, set LED_Mode to 107.

// Copter LEDS by Robert Lefebvre
// Based on the work of U4eake, Bill Sanford, Max Levine, and Oliver
// g.copter_leds_mode controls the copter leds function via bitmath
// Zeroeth bit turns motor leds on and off: 00000001
// First bit turns GPS function on and off: 00000010
// Second bit turns Aux function on and off: 00000100
// Third bit turns on Beeper (legacy Piezo) function: 00001000
// Fourth bit toggles between Fast Flash or Oscillate on Low Battery: 00010000 (0) does Fast Flash, (1) does Oscillate
// Fifth bit causes motor LEDs to Nav Blink: 00100000
// Sixth bit causes GPS LEDs to Nav Blink: 01000000
// This code is written in order to be backwards compatible with the old Motor_LEDS code
// I hope to include at least some of the Show_LEDS code in the future
// copter_leds_GPS_blink controls the blinking of the GPS LEDS
// copter_leds_motor_blink controls the blinking of the motor LEDS
// Piezo Code and beeps once on Startup to verify operation
// Piezo Enables Tone on reaching low battery or current alert
