My motion sensing light is remaining on. I don't

Sounds like the motion sensor is not picking up motion. Or, does it actually sense motion and only stay on for a short time each time? Try moving the setting, if this is the case and see if you see ANY change. If not, then replace the motion sensor.

Very common issue with motion sensing lights. You can either replace the light sensor which is available at most hardware stores or you can disable the motion sensing feature and just have an on-off light. To disable the sensor, (turn off the power!) unscrew and remove the light sensor (it is the reposition-able box under the light.) It depends on the particular light, but you usually just match up the wire coming into the light from the house and the wire from the bulbs and connect them with a wire-nut.

How long has this been going on? Has this light fixture been updated recently? Has the lite switch been changed that operates this fixture?

If there is a "sensitivity" setting, it appears to be sett too sensitive, therefore the unit thinks there is constant motion.

Motion sensing switches wire identically to in-wall timers:

LED bulbs with leaking motion sensors tend to flicker as well, more so than CFL. I switched to Cooper style - but now my Cooper OS310u will sense motion - and keep sensing motion almost all the time. If it's in test mode - it will shut off but otherwise it keeps sensing it. This is in a garage - and door open or closed does not seem to affect it. I have the same unit working in my basement just fine.

suggestion - don't try LEDs to solve the problem and yes - it will burn out your CFLs real fast.

3-way installation shows two motion sensor switches.
Instructions do not show 1 motion sensor and 1 ordinary 3-way switch.

Also note the maximum load rating is 500Watt

Unscrew the bulbs counterclockwise with youre finger tips.

Sounds like the relay in motion sensor. Change the bulb. Rechargeable batteries are no good after 3-4 years also.
