The blinking LED means the detector sees you, and when in test mode, it
turns the lights on for a short time interval, but when the photo cell dies,
it doesn't complete the circuit to allow the lights to come on when dark.
Replace the unit

The photocell is behind a small window on the bottom of the unit. If you
put tape over it, it would tend to come on during the day. It sounds like
the pcell has gone bad

i noticed last week that one set of motion lights on my house wasn't
working at night. The other set was working perfectly in the back
yard. the lights work in test mode but don't work when it gets dark.
i'm a little stumped..i have the settings properly set.. i think. I
read on the company's website something about "light interference" and
they recommended using black electrical tape over the the photocell to
see if helps the problem. What piece is the photocell? are the
sensor and the photocell the same thing? I wasn't sure if i was taping
over the photocell or the motion sensor or are they the same
thing...little help over here..thanks

i forgot to mention that the red light on the motion detector does
blink when someone walks past it...but somehow it's not making it go
off
