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.
Sign lighting and LED upgrades in Trowbridge: the practical benefits
- Where flats sit above shops in Trowbridge, downward-aimed, shielded fittings keep light on the sign and out of windows.
- On a retail park outside Trowbridge, wall washers can light the sign and entrance on dark winter afternoons.
- For a Trowbridge business watching its budget, lighting the existing sign is a sensible first step into evening trade.

Consent for illuminated signs in Trowbridge
Lighting a sign changes the consent picture in England. Under the 2007 Advertisement Regulations, deemed consent for illuminated signs is narrow and is excluded in conservation areas, National Parks, National Landscapes, the Broads and areas of special control; in practice most lit fascia and projecting signs need express consent. Allow up to 8 weeks for a decision, with consent normally running for 5 years. Keep the light static and at sensible levels, with PLG05 the usual reference for brightness, and use a time switch or photocell to control the hours. We check before you commit, can handle the application drawings or the submission, and arrange an electrician for the BS 7671 connection.
