Number plate lights

[BenRR]

Had one number plate light out and one was working, tried putting new led ones in and they don’t work, the one that was working is now not working, anyone have any ideas? I’ve looked up and they don’t run off fuses, I’ve tried cleaning the contacts out but still nothing
Thanks

If it's cheap LED bulbs they normally are polarity sensitive. Try them the other way round. Also, if you have not coded them as LED, the BCM may cut the voltage supply off, as there is not enough current draw.

The LEDs are polarity sensitive, you'll need to get them the correct way around in the holder.
If the central electrics senses there is a problem it will shut down the circuit. This makes it quite difficult to work out the correct polarity for fitting LEDs in there.

Cheers for the replies, I had one flicker then went out again, I’ll try them both ways round tomorrow
