I have a Leyland Roadrunner and have noticed a small red light come on beneath a warning triangle on the speedometer? No idea why this has come on. Dont have a tachograph in as its a horsebox for private use. Any ideas??
k is right, its warning you that you have no chart in. You could get the plastic discs or just pop a chart into each location and that will sort it. Or just don't worry about the light of course!

you may need to put a plastic blank disc in both 1st and 2nd driver positions in tacho.
