Halogen Bulb Replacement Programme
The Project
The three-year planned Halogen Bulb Replacement Programme (HRP) to replace all the West Sussex County Council owned traffic signals from halogen to LED technology draws second year to a close. The programme has successfully converted 70% of the planned sites to LED, completing 63 sites. This includes 5 traffic signal-controlled junctions and 58 standalone crossings. Areas like East Grinstead, Horsham, and Haywards Heath are now fully operating with LED traffic signals.
As we are approaching towards the end of the Programme. Please see sustainable case study attached in the document section to the right along with Puffin crossing leaflet.

Why are we doing this work
The project will contribute significantly towards WSCC pledge to become carbon neutral by 2030 -see Climate Change Strategy (opens in new window). The LED traffic signal heads used on this programme have an annual CO2e (Carbon Dioxide Equivalent) reduction per unit of 71kg against the typical halogen equivalent. 331 traffic signal heads have now been replaced, which equates to an annual CO2e reduction made to date of 23,501kg from the traffic signal head replacements alone.
Additionally, this will reduce the need for annual lamp replacements by about 993 lamps. And over the LED's expected lifespan, it will save a total of 9,930 lamp changes. This will bring several benefits, including cost savings, less disruption for road users, and a reduction in carbon and material waste from operating the traffic signals.
What are we doing
Along with the LED upgrades, the program has undertaken extensive refurbishments, replacing all traffic signal equipment and upgrading underground services to reduce future maintenance. Additionally, improvements are being made to the footway areas around crossings, such as updating road markings and clearing vegetation.
At the programme’s inception, 94 sites were planned. However, 4 of those sites were withdrawn due to further planned developer works and upgrades made through WSCC Active Travel projects.
Third Year Programme
Plans and preparations for the third and final year of the HRP are now in progress, focusing on upgrading the remaining sites, which will primarily be located along the coastal regions of the county.
Key areas include 6 sites planned within Chichester, including the junction of Southgate, Chichester, located adjacent to the Bus Station and Train Station. As well as Bognor Regis, Felpham, Littlehampton, Lancing and Worthing. With some final sites left to deliver in Burgess Hill and Crawley. In total, 27 sites will be completed in the 2025/26 financial year, comprised of 3 junctions and 24 signal-controlled crossings.

May Update
Share May Update on Facebook Share May Update on Twitter Share May Update on Linkedin Email May Update linkThe final year of the HRP programme is now fully underway. To date, five signalised crossing have been completed, with a further three sites scheduled for construction in May. One of the planned sites is the signalised junction at Terminus Road/Southern Gate/Leisure Centre access in Chichester, with work due to take place from 19 May to 4 July 2025. During this period, multi-way traffic management will be in place, potentially causing disruptions. These works are essential to convert the remaining bulbs to the new, more efficient technology.
