Aren't they all?

You need to read the LED trailer lights thread, only 32 pages of light reading - see what i did there.

If your parking sensors are going off when reversing, your car does not know the trailer is there.

As mentioned - read the thread, you need the appropriate pulse buster for your vehicle - or change your trailer side lights if they are indicators to incandescent globes. This will provide the resistance the system is looking for.

That's what worried me. All this time I thought it was the icon blinking that meant it was working properly.

Normally it does. Yours must be on the threshold.
Has your vehicle had all the necessary updates done over the years?

Here is what I did. When I got the van (which came with LED lights) I had the same issue. The van connected up via a 12-pin flat plug rather than the big round plug on the RHS. I got a piece of polypipe from bunnings. I got a plug for the socket at Supercheap and 2 x Load resisters also from Supercheap. Wired up the load resistors to each indicator circuit only and to the Earth pin. Had to do a bit of trimming on the polypipe but the load resistors slide in fine. Just looks like a big dongle, lol. It basically runs in parallel with the 12-pin flat but provides load resistance to the D4 so that the trailer is detected and turns off the reversing sensors. Wrapped the whole lot in black tape. Been using it for over 4 years with no probs. When I tow the box trailer with festoon globe lights I just use a 7 pin flat (on trailer) adapter to large round on D4.

Just add some load resistors to the trailer or build them into the car and switch them. I agree I’d have expected the trailer signal on the dash should mean they’re disabled, but like Tombie says, probably not enough resistance for the reversing sensors?

I agree too, if the dash light is showing a trailer, then the parking sensors should be switched off.

Can you switch the sensors off with the dash switch?
