Sign lighting is external or retrofitted lighting that makes an existing sign readable after dark: LED trough lights, swan-neck spotlights or wall washers, or LED modules replacing old lightbox tubes.
Where sign lighting and LED upgrades can pay off in Derry/Londonderry
- Closing before the Derry/Londonderry evening rush? A timer keeps the sign lit while commuters pass, then switches off.
- Where flats sit above shops in Derry/Londonderry, downward-aimed, shielded fittings keep light on the sign and out of windows.
- On a retail park outside Derry/Londonderry, wall washers can light the sign and entrance on dark winter afternoons.

Consent for illuminated signs in Derry/Londonderry
Light changes the consent position. Under Northern Ireland's 2015 Advertisement Regulations, internally lit, halo-lit and lit projecting signs typically need express consent from the council, applied for online through the NI Planning Portal. A listed building usually needs listed building consent as well. LED modules and drivers run at low voltage, but the final mains connection is made by an electrician to BS 7671, who certifies the circuit. Councils commonly refer to PLG05 for brightness and expect steady rather than flashing light. We check before you commit to sign lighting and LED upgrades and can prepare or submit the application.
