Since 2014 Each year the Haut Vallespir organizes the illumination of the signal towers on June 23rd.
In 2016, during a meeting of the College of Signal Towers in Serralongue, an event of greater magnitude is drawn.
In 2017, The Rempart association meets with the College of Signal Towers and gives the reports of its event and explains the difficulties that the association has encountered. Multiple tests are then organized day and night between the different towers of the Pyrénées Orientales. The event is publicized in the program Échappées Belles.
In 2018, During a Grand Site Occitanie meeting, the event is brought forward.
In 2019, A file is presented to the Department, but the pandemic will block the rest.
In 2020 and 2021, despite the pandemic, the primitive event persists, because it does not require regrouping at a point and is visible from afar.In 2022, the event takes on an inter-Community of Municipalities dimension with Haut Vallespir, Rousillon Conflent and Conflent Canigó under the banner of Destination Canigó País Català and coordinated by the Syndicat Mixte Canigó Grand Site.
