Headlamp bulb warning symbols but all working

Post by cammerz » Wed Oct 09, 2019 5:16 pm

Yesterday I got the warning symbols that both my dipped beam and full beam headlamps were not working but upon checking both lamps all the bulbs are functional. I've checked the connections on the headlight assemblies and everything is fine but the warning symbols still appear on startup.

Is the car able to detect when the bulbs are on their way out or is there a fault?

The car performs a continuity check with just 2V. It could be that you have a bad earth somewhere, with too much resistance.

Thanks for the info, I can only imagine that's going to be difficult to pinpoint but I'll keep my eye on it.
