Electrical Wiring in the Home/Outdoor flood lights


Hey there!  We have a set of two motion sensitive, hard wired flood lights on each corner of our home.  They come on at dusk and get brighter if there is motion.  They suddenly all stopped working.  We thought it was odd that the bulbs would all go out at the same time, but we bought new bulbs anyway.  The bulbs are the same ones I've always bought (inside/outside) and used one inside so we know we didn't get eight defective bulbs.  Circuit breakers are good, no recent wiring changes, other than 14 days of relentless rain, nothing else has changed.  The house was built six years ago; could the units themselves all have gone bad at the same time?  Thanks for your time!

Electricity is dangerous!
You can be injured or killed!
Improper installations can cause fire, injury and death!
Are you qualified to do this work?
National Electrical Code definition, NFPA 70 2008 Article 100: Qualified Person. "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."
Electricity is fire in a box! Death on a leash!
You are more likely to be killed by 120 volts than any other voltage [120 volts creates the PERFECT fatal current through the human body's electrical resistance!]

Let me here first state that I believe the first best use for motion sensors is as land-fill.

The units certainly could have gone bad after six years, but both together? If they did it is probably due to a surge - lightning, etc.

What occurs to me as the most likely cause is a failed splice in either the hot or neutral of the circuit. It could be anywhere from the panel to the last common point, maybe an exterior junction box at one of the fixtures. It could be a broken conductor at an over-driven staple [unlikely]. Are these controlled by a switch anywhere?

I encourage you to secure the services of a competent, qualified electrician.

Good luck
