Headlight Issue
Hey all.
I'm having troubles with my headlights in the Baja.
Ever since I wired the car when I switch from high to low beam the little blue light on the speedo stays on, it just gets dimmer. I've also noticed
that when the high beams are on the low beams are also still on. The wire is run from the high beam wire that runs from the fuse box to the back of
the headlight.
I've just added driving lights to the car and I've also run the feed for the switching relay off the other high beam wire that runs from the fuse
box to the back of the light. But the spotlights are always on, high or low beam makes no difference, the same as the dash light. As far as I can tell
(I've checked ten times) all the wiring is correct and brand new. I made a whole new harness for the car when I built it and it's only 3 months
old.
Can anyone help or make suggestions of what to look for?

It doesn't have a headlight relay.
There is one on the spotlights, it's brand new and working.

Your getting feedback on both sides so your dipper switch mustnt be switching between both sides properly
probably got moisture or crud in it

It's a 6V car but it's all been converted to 12V.
And I tried three different dipper switches including a brand new one, made no difference 
Any more ideas?

If its not in the switch then you've got a crossed wire somewhere, probably the insulation has chaffed through and they're touching together

Will have another look tomorrow. The only thing that worries me about this theory is that it has been like this from day one. So unless I bared the
wires during install they're unliking to have rubbed through overnight.

Yes. The car has all new wires front to back.

sounds like you have not got a good earth at both, or one of the headlights so its back feeding through the other filament to get to earth..somewhere.
Make sure that the common return wire (the 3rd wire, not lo beam feed, not hi beam feed), at each headlight is really well connected, and follow it
back under the bonnet area to where it should jump out of the loom and be screwed into the body steel.

Ok. So I changed the earths from the headlights to the body and made them a little beefier. And checked over every single wire again, pulled the
headlights out and checked the plugs on the back to make sure they weren't touching or anything.
Problem is still there.
Can anyone suggest a method of testing so I can determine where the bleed from the hi beam to the lo beam circuits is occurring. I've been messing
around with a multimeter for a little while, but what can I say, I'm stupid and don't really know what I'm doing

Steve I owe you a drink my friend!
The wires we around in an incorrect order. I swapped them and all problems have been resolved. I would have never even thought to check there. Low
and high beam work perfectly, no blue light in the dash on low beam, and the spotlights are behaving how they should.
Many thanks, problem solved.

Hi
Glad to help.
That image I posted is handy to have around, its the same wiring order for any car, colours may vary.
Notice the the way the VW engineers did the wiring, brown for earth, white for high beam as they are brighter than yellow for low beam.
