Indicator dash flash

Hello I wonder if anyone can confirm my thinking, when I use my indicators left or right the dash light doesn’t always flash, the outside indicators all work but the display light doesn’t always.

Loose bulb or wire to bulb

Thanks for that i'll certainly take a look

Got the same fault on mine.I found its the flasher unit that is located underneath the steering wheel to the left and behind the fuse box there.Check connections.If ok you can remove the unit easily and the actual working bit slides out of the housing so you can check it.

Thanks for that appreciate your help

There are two main circuits in the indicator relay one to look after the external lamps and the other the tell tel lamp in the dash, thats the one thats failed, therefore a replacement relay is required.
Get the the correct relay as some have a third circuit that looks after trailer lamps.

The relay is pluged into the front of the fuse box on a 300 series disco so easy to change.

Sometimes I get a little trailer light up on the dash...........and sometimes, I don't!

I has that once years ago just remove the towbar socket, cleaned tightend the terminal screws and a dab Vaseline over the bits and that was it, and the last time had any problems.
Worth a look maybe, other than all that's left is the relay

I had the binnacle to bit’s this afternoon checked bulb as suggested all ok there, so as discool has suggested a new relay will be installed mine has 5 spades, as you say two circuits , one is working other is not. Thank you for your help I will report back once I have new relay in.

OK, it's important that you get the correct one with the same lamp loading , just the same as your existing one really.

Thank you discool you were spot on with your answer, I removed relay and gave the whole thing a good scrub inside and out, gave it a bath in the trusty wd40 and cleaned the contacts with an artist’s brush, installed it back this morning and all working fine again, but I will get a replacement anyway. Thanks again.

That's something I didn't think of... 'remove and clean'... and it works, well done Gunny.

ever since I`ve had my disco 1 its done that too,
its just the one flash when the other light flashes for indicators.
puzzled me at first,
now 1000`s of flashes later, I got used to seeing it.
my trailor lights all work as they should, plus I reguarly lift the socket cover and give it a blast of WD40 to keep it clean inside.

I would imagine its only supposed to come on when you've got something plugged into the towing socket. I'm going to have mine to bits and give it a good clean, see what happens.

My trailer light does the same, one flash when the indicators are first switched on.

Its done it on a couple of my discos now so presume its normal.
