What the variable message signs on the Brussels motorways, ring and tunnels currently display, one entry per sign: up to four lines in French (fr_l1–fr_l4) and Dutch (nl_l1–nl_l4), an optional pictogram URL (picto), and a status ("OK" or "Non OK" when the sign is not reporting). last_update is in Brussels local time. There are no positions here: join on id_mobigis with the message-sign-locations endpoint.
