Dash Trailer Light does not light with indicators

[fearofweapons]

The dashboard trailer light, green square with a picture of a trailer, does not energise. I understand that it is supposed to come one once per indicator activation without a trailer and every indicator flash with a trailer attached.

​The bulb is good.

What causes this to activate? Is it controlled by the relay? How would I tell if I have the correct relay?

It should be noted that the indicators do work as expected otherwise.

This is on a 1989 110.

Many thanks in advance.

From memory (sepia tinted) when I first bought a new Land Rover I had a similar thing happen.

It was sorted by changing the relay

to this.

Earlier variants used something like this.

Thanks Neil,

I'll give the second relay you link to a go I think. Looking at the first I struggle to see how that would work as it only has three pins?

regards,

Richard
