From Gemini: It should be in the Main Firefly touchscreen/ main control panel. Tap the lights icon, then look for a button labeled, utility, service or docking. It may be tucked under an "Exterior" sub-menu within the lighting page.
There should be a manual override switch in the wet bay or on the dash to the left of the steering wheel.
The switch in the wet bay is so you can turn on the lights if working there at night.
Keep in mind, It may be motion sensitive.
