Hi I have plugged my trailer into my 2011 Discovery 4 and have all running lights, tail and indicators but no brake lights?
I plugged trailer into other car and works fine. There seems to be no power to the plug from the brakes,
Checked handbook for trailer brake fuse and lists
11 Trailer reverse lamp
27 Trailer side lamps
48 Trailer battery feed
54 Trailer connector ignition feed
There seems to be no fuse listed for trailer brake lamps? Any suggestions
Thanks
David

I am a D3 owner and the brake light fuse is number 1 (7.5A) inside the removable cover in the left hand rear of the vehicle. I.E. open the tailgate and stand behind vehicle and reach in to the left and check.

I don't know if there are fuses there on the D4. However the info should be in the owners manual if you have one.

There is also a large plug in there so check the wiring as it may be a broken wire from fuse block to trailer connector.
