If you have replaced any of your lights with LEDs (especially the side lights) you will get this as there is typically not enough power being drawn. If you have done this, you may need CAN bus LEDs for the side lights that have some built in resistance. Even with this, it can be enough to cause this fault. Replace with a standard W5W halogen and the fault should go.

You are right. Could these cause any problems or can I just leave them?

It depends really - as sometimes LEDs liike this can have other effects - like flickering or flashing on occasion - and you may not be aware of it, but it could be a distraction for oncoming drivers - so has obvious implications. The MOT may be another issue. Also, when the engine is switched off, sometimes the LEDs will glow for some time afterwards..

So either opt for some CAN bus LEDs that have load resistors if there are issues, or go back to W5W halogens.

I have LEDs for my sidelights, I'll try and dig out the type I fitted. I have Xenon Directional Headlamps - so a different headlamp entirely with different bulbs and wiring, but still use the W5W for the sidelight in the headlamp.

These are what I have fitted, but they are bringing out new ones all the time, so I don't have the link anymore.
