Pixhawk4 & External LED

Hi, i am using pixhawk4 and i’d like to know using External LED which is [Pixhawk PX4 RGB External LED Full Color I2C LED Module] with Ardu Pilot 4.4.2v firmware.

when i use px4 firmware the LED match with GPS (M8p rover lite).
however when i change to Ardu pilot 4.4.2v firmware it doesn’t match.

Is there any parameter for external LED for match with GPS?
or what firmware support for external led?
