Driving home in the dark tonight I totally lost my headlights on both main beam and dip, I had to drive on fog lights.
This happened 5 or 6 times. I fitted led units almost a year ago and they’ve been fine until now.

I’m not electrical but a hammer wielding mechanical gadgy and any help or advice would be greatly appreciated. 64 plate TD4 SE

Have you swopped the relevant fuses ?

I haven’t checked anything yet but I don’t think it will be fuse related, they were coming back on for a few minutes and then going off again. I’m going to remove the headlights shortly to see if the led units have caused overheating and damaged anything. 64 plate TD4 SE

Have you tried putting back the old globes. Procrastination, mankind's greatest labour saving device!

This would be worth trying.

if you say you fitted LED I assume they are a non-standard fit? First step put the original lamps back in (assume they are HB3 at that age) as they use a single filament/source for both dipped and main, so you would lose both functions in a single headlight from a single failure.
LEDs cycling would suggest overheating - fan cooled heatsink and fans have died? 2000 Xei 1.8 gone

Overheating seems likely. The original bulbs have a short lifespan (prompting people to change to LEDs etc) because they overheat.
My limited experience of LED upgrades is that they can get surprisingly hot and need to good ventilation Jules

Thanks for the comments. I’ve actually put the Hb3 halogen bulbs back in now and left it running for over half an hour with no problems. A friend did an OBD scan for me and it showed intermittent faults with the left and right headlight circuit before I changed the bulbs back to standard and after running with the lights on it showed no circuit faults.
I’m not totally confident that it’s fixed because I can’t understand why both sides would fail at the same time.
But as I said in the original post, I’m mechanical not electrical background 😊
The fault codes thrown up were B1D01-15, B1D00-11 and B1D00-15 and I haven’t a clue what they are, I’ll just have to see what happens next time I use the headlights. 64 plate TD4 SE

You could always try looking.
