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 Caernarfon: the practical benefits
- A painted fascia on a Caernarfon high street can stay readable after dark with one slim trough light.
- Heritage frontages in Caernarfon may suit discreet external lighting, often easier to justify to planners than a new lit box.
- An old fluorescent lightbox on a Caernarfon parade can be converted to LED, cutting running costs and tube changes.

Consent for illuminated signs in Caernarfon
Adding light usually means adding an application. For an exterior illuminated sign in Wales, expect the council to want an express consent application in most cases; the 1992 Regulations (as amended) set the rules, and the council can confirm its timescales and conditions. Expect questions about how bright the sign is and when it is lit: steady light, a time switch or photocell, and luminance kept within the PLG05 guidance all help. We put together scaled drawings, photomontages and lighting details for you, or lodge the application ourselves if you prefer, and an electrician makes the final connection to BS 7671.
