One of my headlights on my 95 Legacy SW blew (well I thought it had). So off to the local automotive car shop for 2 new bulbs, thought I might as well get 2. Went to put it in and the light that I had thought had blowen (left hand side) hadn't. Instead the plug had sh1t itself! More specifically the earth connector had, bulb was fine. Back down to the shop and got a new plug. The 2 power wires I put back together and the earth wire I earthed to the battery earth next to where the headlight goes in. I did this after talking to the chap in the store as he said sounds like a dodgy earth, give it it's own earth to the body.
Now... the right hand light works fine, however the blue light on the dash to show full beam comes on very dimmly even when the light are on dip, left hand light is slightly dimmer then the right, and when you flick to full beam the dash light comes on normal brightness, right hand light flicks to full normally and the left hand light gets dimmer.
Something obviously isn't right...
Where the battery earth goes onto the body next to the left hand light, is this not an ideal place to earth?
I'm 99% sure that I put the power wires around the right way....
Anyone have any ideas?
