Outdoor motion sensor light stays on — Valencia, 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.
Why this is common in Valencia
Many of Valencia's pre-1990 buildings still carry aluminum or outdated copper wiring that does not meet current REBT standards, and electrical panels frequently lack residual-current devices (RCDs) required since 2002. The city's aggressive short-term rental growth has driven numerous unauthorized apartment conversions where electrical capacity was not upgraded, creating overloaded circuits. GVA boletines (completion certificates) are required after any installation work, and inspections by an Organismo de Control Autorizado (OCA) are mandatory for certain categories.

- Light remains on 24/7 instead of turning off after the set timer duration
- Light turns on by itself with no visible motion — triggered by wind, animals, or heat sources
- Switching the fixture off and on at the breaker doesn't reset the sensor cycle
- Sensitivity and timer dials have no visible effect when adjusted
- Photocell (dusk-to-dawn sensor) doesn't prevent the light from running during daylight

Emergency services in Valencia respond within 30–90 minutes in the city core (faster in l'Eixample and Ruzafa, slower in outlying districts). Callout rates run €50–€130 plus €35–€65/hour including IVA. Post-DANA (November 2024) contractor availability in the southern metro area (Horta Sud) remains constrained due to ongoing flood remediation work — expect longer waits and higher rates for any flood-zone adjacent property.
