Power 240 v ac light from two power sources

by user1759818   Last Updated August 13, 2019 21:21 PM - source

I have existing led lighting in my garage 240 v ac which operates from a pull switch. My garage door opener provides a facility to power a light with 240 v ac as well. What if any additional circuitry, if any, would I need to add if I connect the garage door opener to the same light to cover the situation where both supplied power at the same time?
