Headlamps or bad earth?

[sup3rm4n]

Hi everyone,

I have a weird one: basically, the last couple of days, when I pop up my headlights on dipped beam, sometimes the lights come on and sometimes they don't (currently not at all). I have noticed that if I rev the engine a bit to increase the voltage and then pop them up, this can sometimes help to get them on. Full head beams work fine and so do the side lights without any issues.

In addition to this which I am sure is linked, I have also noticed a that the voltage gauge on the dashboard is only reading up to 13v where as the needle normally reads at 14v when reving or when the car is running.

What do you think it could be?

Please let me know

Thanks

I've had this on my N/S headlamp

I have a similar issue but on the rear lights I belive it is a bad earth as i'm only reading around 9V at the bulb
