Marius, is this what you're talking about?

It's normal for the trailer indicator to light up once when indicating when no trailer is connected. If there is a trailer connected it will keep on flashing with the normal indicator lights.


Not if the trailer lights are LED. Insufficient current to power up the warning light as I found out after replacing my trailer lights with LED ! Still flashes once when indicators are used exactly the same as without the trailer. 2007 TD5 90 Hard Top

Worn A frame balljoints are one of the most common causes of clunks in Defenders. Steve.
Owned numerous Land Rover vehicles of all shapes and sizes over the decades.

Yes that's the A-frame ball joint. The ball joint develops play or the bolts holding the arm.

So the (klank) is only there when you change gears at clutch engage. Now I believe the power split is not entirely 50/50 rear/front so there is a slight discrepancy in "pull" causing the play to be taken up at that ball joint. And if there is play in that joint it makes the sound.

Would probably just worsen and worsen over time. that's my theory anyways......not sure if't correct but it sure stopped that noise! Smile

One of these may help if you want the light to iluminate...

To be clear, the trailer icon flashes once when you indicate to let you know that it is working and will stay flashing when a trailer is connected to indicate that the trailer indicators are working. It does this by sensing the current drawn across the flasher relay.

This is why LED trailer lamps will not make the trailer indicator flash, as they draw too little current to detect. Not even if you fit one of the LED relays as linked to by TR51 - they are for LED lights on the tow vehicle (as the description makes clear near the bottom). The only way to make any combination of LED lights and filament bulbs work is to fit a proper LED relay and separate trailer relay - which involves a lot of messing with the wiring...fine for me as my truck is in bits on the drive but probably a little much for most people!

Anyway, back to the topic in hand.... Real trucks don't have spark plugs

Fair play that nails that part of the thread, thanks for posting. So clunk means back to landie to sort under warranty (as i have 8ish months left)

cheers

You can buy Puma seat belt sockets with the switches in so the seat belt warning light function must be a requirement in certain market areas and available.
