Trailer wiring

So my disco appears to have the factory wiring fitted.

I can use either trailer of mine and all lights work well.

However there is no trailer symbol on the dash or buzzer for the indicators.

Any ideas what is wrong? One trailer has LED and one has conventional bulbs.

LED lights require resistors and relays, resistors so the car will detect a load on the trailer lighting circuit and relays to stop the LED's from pulsing or flickering.

I’m aware of that, however the trailer with conventional bulbs doesn’t work the trailer symbol on the dash either?

Do you know if the trailer light ever worked? It could be blown.
