The headlights are not individually fused but check the 40A and 50A fusible links in the engine bay fuse panel as they supply the BCU which powers the headlights using transistors (FETs).
Hi there
Apologies for the basic question.
The headlights stopped working on my 2013 Disco 4. High beam and everything else still works. I think it's a blown fuse but the book is not clear which one does the headlights. I've tried checking a couple of fuses but all were ok. Can anyone advise what number fuse is for the headlights.
Thanks in advance.

Did you find the cause?

The one 50A fuse supplies the dipped and main beams and fog lights, switched by the several FETs inside the BCU. If any of these lights are working then the 50A fuse is OK. If there is a short circuit on any 1 light/beam then the FET won't supply power to that light/beam but will to the same light/beam on the other side as there is 1 FET for each bi-xenon, high beam and fog light.
In case the light switch is the culprit...
Does high beam work when switching to high beam or only when flashed?
Do the parkers work with the light switch on parkers?
Does your vehicle have high-beam fill-ins or DRLs? I don't recall when DRLs replaced the fill-ins.

Check your globes wouldn't be the 1st time I seen 2 blown filaments .
I have a similar problem but only 1 side so I presume it's simply a globe.
Anyone know an easy way to tell whether they are halogen or xenon ? From looking at a PowerfulUK video there is a ballast at the back of the headlight for xenons.
Mine is a 2013 HSE made October that year.
Saw these if halogen as I would probably replace both sides assuming that the other will eventually fail too.

If they are xenon, you would know it. When you first turn them on, they flash very bright and then the light intensity drops right off before slowly coming back up to their normal operating state.
Light output from xenon is very white - almost blue, whereas halogen globe output is yellow by comparison.
