It's probable that the LED's do not draw enough current to activate the warning light, in effect the BCM is unaware that the trailer is present.Sorry to jump in on this thread rather than start another.
I’m a new owner of a 2003 HSE tdv6. It’s got towing electrics etc fitted. I was told when I did my trailer test (many years ago now) that every vehicle needs to either flash an extra light or make a beeping noise when indicating with a trailer connected. Mine doesn’t... all trailer lights are working (leds) and I do run a camera to watch the horse while I’m moving (runs off interior light wiring), but I’m concerned (slightly) that it’s not doing anything when I indicate to remind me I’m towing (not that I can forget my best friend in the back, but you know what I mean.) I am using an adapter for the 13 to 7 pin socket.
Any ideas please?
Hi Guys - I’m in the same situation as Garwillis - trying to find the tow relay - great to see the part number already posted - my relay box looks like it has a flat blade jumper where the relay should plug in - presumably it pulls out? Can anyone advise? Perils of 2nd hand parts I guess with no instructions...

Not sure if this will help answer your question, but maybe. The visual indicator, is not to remind someone they are towing , if they are not aware of that , they should not be driving. Especially as all drivers should be frequently checking ALL mirrors! It is to tell you that the trailer indicator lights are working.
The visual or audible warning must tell you that your trailer indicator lights are working, rather than bulb failure light, which tells you they are not.
Check your owners manual to see if you have a visual or audible warning system. If not, time to get one wired in.
Hope this helps.
P.s Just noticed trailer lights are LEDs. This may be the issue. People cleverererer than me can tell you why @Saint.V8 , @holidaychicken , @wammers and @ others who might know
2nd addit: Considering where you work/ed , surely someone there would know the answer to this, and can give you hands on help?
If you're lucky @Saint.V8 will see he's been tagged and explain the issue with LEDsThanks. I don’t often forget I’ve got a trailer on the back, it’s usually when I take it off I can’t remember which way to turn the steering wheel to park!
My friend can wire a buzzer in for me if needed. I towed again today with the camera running off the lights and I did check everything was working before i left as it was 2 hours of motorway with my precious horse on board so I’m guessing it’s cos they’re leds. As I’ve not found anything in the handbook. Will have another look though..

Addit: I'm working on the premise that the screen for the camera in the horsebox cannot be seen by you whilst driving? Otherwise you are on a sticky wicket.

Sounds jerry-rigged to me as she says "and I do run a camera to watch the horse while I’m moving (runs off interior light wiring)"Usually the camera is triggered by the reverse lights so only while reversing. Unless this is something jury-rigged.
I believe, due to the fact the trailer is on LEDs, they are not drawing enough power to tell, the appropriate brain, they are there. I'm sure there be a workaround, but it's black magic to me.Rather than a buzzer just add extra (normal) bulbs somewhere so it draws enough current.
