Shut up Rob !
Right had another look and used my multimeter to see what was going on. checked all connections(earth as well !!!) and all looks fine.
Right, this is what i think is happening:
The flash/pass light works fine - both on high beam and flash/pass switch.
The main beam works fine.
The side lights look fine.
I have not used the double earth connection for the lights (just the indicators).
I have not used the earth from the sidelight.
OK so when i check the voltage on the highbeam wire i can see 10+ volts going to it when i press flash or put the high beam switch on. The high beam warning bulb works fine when on high beam or flash.
BUT....................why do i get about 4-5 volts going
from the headlight bulb up the high beam wire when i switch on the normal headlamp ? this is what is lighting up the high beam warning light -albeit very dimly. I THINK ! - This is what john said to check and i assume that there should NOT be any voltage going to the high beam when not on !!!!!!!

not enough to light the high beam filament, but enough to light the high beam warning light ? Sorry, this prob sounds very confusing.
Any ideas ?
