Backlit means that the OOH surface has integrated lighting behind the poster or print, delivering even brightness, stronger colours and high legibility at any time of day. Instead of relying on surrounding streetlights or daylight, the message is illuminated from within, ensuring it stands out clearly even in darkness, rain or snow.

This has a major impact on out‑of‑home effectiveness, particularly in the Nordics. With a backlit surface, the message remains visible and consistent day, evening and night – no campaign “disappears” after sunset, which is otherwise a real risk for much of the year. The uniform lighting provides higher visual quality and better contrast, making it easier for the eye to notice, read and remember the message. This strengthens both long‑term brand building and immediate campaign response.

Backlit sites are also typically perceived as more premium – a position JCDecaux actively aims to occupy. The visual impression is cleaner, more controlled and more polished than a dark or unevenly lit surface. This can support higher value perception, stronger price acceptance and a more compelling overall brand impression, especially in business‑critical campaigns where image, quality and trust are central. For the brand, backlit OOH sites ensure that the message maintains the same visual standard around the clock, which is particularly important in the Nordics, where extended dark periods mean lighting effectively determines whether the campaign is seen or not.
