Hi Guys, just getting the bike ready for mot. The headlight on full beam is bright but on dip goes dull. Then I found that on dip both the elements inside the bulb are both on at about half brightness. Any ideas why both elements are being powered up?

You have the three wires going to the bulb crossed,swap them round till you get the it right!
