Boy did we need one !!!!!!! a long time today head scratching as to how we made our choice of headlamps work ! We had decided we wanted the all in one headlamps, some I know think they are fugly but having seen them in the flesh thought they looked okay so once again emptied the wallet !
No doubt those of you who are wizards at wiring will find our tale amusing but we came upon some issues we had not anticipated and which caused us to use the grey matter. We had anticipated that to make day running lights legal they had to go off when side or head lights were selected so from e bay I bought a wiring harness with a relay built in which was perfect for the job, at least the blurb said so !!!
After struggling under the car and threading the wire up through the rubber grommet we got it connected and with a multimeter tried the lamp ends to see if all was good, it switched alright, but it switched the negative wire not the live feed. As the all in ones use a common earth for LED side, this unit was as much good as a chocolate fireguard. I did open the relay to see if we could re position the wires but found out it contained a dimmer unit which we did not need and was encased in resin so not modifiable. Back to the drawing board. A visit to our local suppliers and we purchased a relay, mount and some wire and without too much trouble simplified what we needed and miracles it worked, the relay attaches to the others so will be very neat when finished.

The headlamps in these units work by an illuminated bulb which has a shield which raises and lowers for dip and beam. It follows the bulb must stay illuminated all the time because it is the same whether on dip or beam. Of course the car is wired so when beam is selected the dip wire is off so we had dip and off !! not good !. Having worked out that we needed a constant live for the bulb and use the other wire as a switch wire a bit of head scratching and Joe was able to work out how to make our dip switch do this. A bit fiddly with lots of small links but after an age all worked. Not everyones cup of tea but we like them ! and they certainly taught us how to think about wiring !

Looks good - it will be worth all the head scratching in the end.
