Outdoor motion sensor light stays on — Alicante, Valencian Community
An outdoor motion sensor light that stays on continuously instead of cycling off after a set time wastes electricity and loses its purpose as a security deterrent. The usual culprits are a misadjusted sensitivity dial picking up heat from HVAC vents or passing traffic, a stuck relay inside the fixture, a faulty sensor module, or the fixture being left in manual-on mode after a power flicker. An electrician can recalibrate the sensor, replace the photocell or sensor module, and verify the wiring is correct.

Spanish REBT requires boletines eléctricos for all installations signed by a registered instalador autorizado. Many buildings still have outdated aluminum wiring in communal areas from 1970s–1980s construction.
