yeah the randon fuse I have is proably meant to be in the box, I would switch the lights on and give the headlight wires a fiddle too see if any are dodgy. Besies that im fresh out of ideas, I hate electrical faults.
 
taken 2 pictures to maybe help.
first picture is high beam (only works on drivers side)
and the secod is on dipped beam which is fine

did you put the bulb in upside down?
or else it could be the wireing for the fuse check the conections with a volt tester
 
Get a new bulb, some bulbs look ok visually but don't work. Or just put the bulb in from the passenger side to test it.

Does the plug look burned or a bit bubbly?
 
my headlight prob is different - switching bulbs proves that on the driver side the bulb will not do normal beam....full beam is fine.
when the stalk is twisted for full beam the headlights use a different section of each bulb for full - low and normal operate on one section of the bulb, full beam uses diff section.
i got a new bulb for 8 squid but prob persists as it is connected to prob with fuel pump in my case .......argh!!
try a new bulb? maybe you can't really see if one section has gone.
 
Take a good look at the headlight fuse holder. Im solving mine at the moment to get her ready for MoT. Basically the holder had completed corroded on one side so when I replaced the fuse for it there was still no circuit. So Ive had to take that connection out and replace with new.

Failing that try another bulb and get a meter on those wires.
 
I had the dim/dip problem where both headlight and main beam were not working on passenger side but didn't know about the dim/dip unit at the time.

I added a couple of relays and took a feed off of the driver side headlight/main beam.

was gona say relay worth a chek-change scrapees
 
ok i sorted it thank god.
thanks everyone for all your help,
i turned out that when the bulb plug was replaced due to it burning out (bout 10 months ago) that the earth was connected up wrong so it had been fine all this time as it had been drawing its earth through the dim dip box as thats earthed but recently given up and that explains the draw of power. now better than ever and all my earthing point are cleaned up and connectors clean.
thanks again everyone:laugh:
