Front fogs (LED) flickering?

Im either going mad, or I did just see it. would my front LED foglights flicker? Ignition was on, and I'm sure they flickered a couple of times, as in not even a second each time.

And last week a mate was sure he saw them flicker too...
What could cause this??

I dont know about Land Rover but some cars (my VW Touareg) used to pulse the bulbs for a very short time, not enough to heat up a conventional filament bulb to test if it was there and OK. LED's react quick enough to illuminate at full brightness momentarily. It sounds like may be a possibility. BMW i3 Electric Car

Yes & No sir.....

Im sure PC Plod might have something to say about flashing lights on the front of your car!

To be 100% correct, you should have the Hot monitoring turned off in the cars configuration files (CCF) As they are LED's you could switch the cold monitoring off too

Ahhhh good point....

I'll be clearing faults and error messages over the coming few days once the new front air struts have been replaced so will see about switching the Hot (& cold) Monitoring off

Thanks guys
