That is correct Gary, its been a legal requirement since the 80's that the driver has visual indication that the towed vehicle indicators are working.

That's not strictly true though Mark. It is widely accepted that the legislation can equally be interpreted that the driver has visual indication that the towed vehicle indicators are not working.

Many newer designed cars (last few years, not D3/4), with their complex electronic systems usually connected to the manufacturer supplied loom rather than an aftermarket one, tell you when the trailer lights don't work rather than when they do.

This is the case on our Volvo; hooked up the van, popped out one of the indicator bulbs on the van, put the indicator or and the dash display helpfully comes up with bong "Warning trailer LH indicator inoperative". Because I was bored I tried the same test with a brake light on the van and sure enough bong "Warning trailer stop lamp inoperative" displayed. The car doesn't display anything when the lights are operating correctly.

Has legislation changed now, is the audible warning no longer legal
