Iveco 75e15 warning light?

No, its an old horsebox that I bought privately. Could this be something bad??
Light never came on when we test drove, seller is a haulage man, it was his daughters horsebox and all work was done by his mechanics. I will have to take it to my mechanic I think. Its typical as my last horsebox which was much newer, sensors for this and that and had ongoing problems with dashboard lights.
The light came on after a motorway drive home, pretty much as we got home, it went off, came on again, then went off and stayed off. I hate mithering the mechanic, after my last dashboard light problems, I fear he thinks Im obsessed with it.
Thanks so much for replying

thanks, could this be caused by settling as it had a new brake fluid pipe. Also what is the hydraulic system, sorry to sound thick but I havent a clue and that sounds potentially expensive

could be low brake fluid [may be a leak on hydraulic system]
