Anyone familiar with PIR motion lights?

I have these for closets around the house, but id like to put one under my bathroom medicine cabinet to illuminate the sink. The PIR motion sensor only works in the dark, does anyone know if there is a way to modify or trick the sensor to work in all light conditions?

Just get a light bar with an on off switch or that can be wired to a switch.

so, PIR works in light just fine, the trick is that there is ALSO a photo sensor for visible light, which keeps the system from turning on when there is ambient light, if you can find and then block, or disable the photo sensor (piece of tape should do it) it should work the way you want.

Awesome thanks. there is a plastic dome over the PIR, I’ll pop the dome off one of my closet lights as a guinea pig and poke around to see if I can manage to block the phototransistor

theres a chance it’s an integrated one-piece sensor, but even then you can still probably block the portion of the lens that contains the photo transistor while still allowing the PIR to function.
