Raynor 170-7 Wiring Question - Courtesy Light (Need More Light)

Have an old Raynor 170-7 that came with the house and is working fine... but light level is rather low.
Interested in what the "Courtesy Light" screw terminal connection if for? Might I be able to slave additional lights from that? Can anyone tell me its function and limitations?
Failing that, does anyone have a clever 'slave light' circuit that will trigger the overhead lights when the (timed) garage door opener light is on?

You can add a second push button to terminals #1 & #4 that will control the light on the opener - this is the Courtesy Light function.

Got it.
THANKS for the quick reply!
