Green trailer symbol on dash

Hello All,
I hope you all can help me with this please .

I have a Land Rover tow bar on my Disco and yesterday moved a small trailer with it by a company called ERDE...my understanding is the indicators should make the green trailer symbol appear when i use the indicators.(Disco is a Jap import)
Nothing appears on the dash when using indicators.
In the handbook it says if it does not come on you have a bulb gone.I do not ,checked with a helper all work correctly.
Trailer has LED bulbs I was told if that makes a difference....Disco is very standard.

For most of Discos life he never had a tow bar...I put one on in 2020 during lockdown because I was bored.
I have a tow bar tester and that sayes all working fine....I understand that its a legal need to have this green trailer symbol working so thought i would try to fix it.

I have searched in the forum, found some stuff but not like mine when all bulbs work.

I wondered do i need do adjust something with Mr Nanocom?
Thank you all.

Fit resistors to the trailer indicator circuits or change LEDs for lamps with conventional bulbs.

As above. Canbus compliant LEDs would work too

I think you are overthinking this.
In the scheme of things Land Rover, this is a minor problem.
With no trailer hitched up your truck will still pass its MOT.
With one hitched up you are already happy all is working OK/
So no worries!!!

Where does this come from please?

Thank you do i fit them in the trailer wiring i assume?...I read that the Land Rover wiring for the TOW bar had resistors in the loom, but from memory never saw any in the socket . I only fitted the basic socket, did not fit eon that charge the caravan fridge etc.

I know it helps to confirm that you haven't lost the trailer somewhere on route, but wasn't aware it was a legal nicety. LED generally don't draw enough current to trigger the "I am towing a trailer" indicator and for that reason, amongst others, LED's are the work of the devil. They should be banned!
Just my humble opinion.

Here we go have a read on this ...they say since 95 you have to have a warning device audible or visual.I am not going to worry to much ...new bulbs would be easy to do i hope!
Thank you all for your input.

You're welcome!

On my 96 with normal bulbs on the trailer I just get a “flash” from the dash, sometimes, when using the indicators, I’m not sure when the light is supposed to come on, on the dash.....it’s not a legal reqt in NZ for sure.

With no trailer on you should get 1 flash from it when you indicate, with a trailer on (or with hazards on) it should flash with the indicator telltale lamp.

Thanks kev
