Last week I tackled the FL headlight upgrade. I tried the relay circuit and like everyone else, lost my full beam indicator. I tried a more simple circuit that mimics the H4 wiring (i.e. separate dip and full) and the full beam indicator functions correctly. The full beam is more than bright enough on its own and the switch-over is instantaneous - it functions just the original H4 bulb. The circuit is below:
Just a few more words so that they don't get buried at the bottom. While I was trying to get the relay option to work I discovered something, it's feeding the 12v onto the dip circuit that causes the full bean indicator to not function. When I placed a diode in the circuit to prevent the 12v going back up to whatever switches the light, the full beam indicator would work but the full beam would not switch off without switching off all headlights. I am wondering if a fully isolated relay circuit (where the both dip and full headlight feeds only switch relays and a separate 12v feed) may work. I have wired with bullet connectors so that I can try this another day. Also I managed to get some H4 plugs rather than cut into the existing wiring (http://www.ebay.co.uk/itm/180596756261).

Interesting
if i put my full beam on ,then pull back slightly ,the stalk sticks half way, and puts dip and full beam on at the same time ,
makes hell of a difference to the light output

Hi, yes you are more or less doubling the output and I guess you are getting a wider spread nearer to the car. It would be good to get both dip and full working at the same time and also have the little blue light come on too but it seems like the PFL electrical design does not support that easily. I am definitely going to come back to it because it is challenging me, but it may involve the use of a few relays and a new live feed. By the way, I fitted the Osram Night Breakers that get a few mentions on here and they are very good on dip and full.

Ive got the official 2003 model electrical wiring book. Youre welcome to borrow it.

Thanks for the offer, I probably will not be able to do much for a week or two but if you could copy the relevant pages (scan, camera or photocopy) then I may get a clue or idea from it. Some components such as the combination meter, are just 'black boxes' and you can only guess as to how they may work.
I looked at the wiring diagrams for the 2000MY, the helpful ones were:
01-Electrical wiring routing
06-HEADLIGHT
27-COMBINATION METER
F-Relay Locations
J-Power Source
I couldnt possibly do that as it would be a breach of copyright. Happy to send it to you, just send it back when youre done. s:) :) s:) PM your address and Ill post in the morning.
Just a little info for you but the full beam light has two neutrals on the circuit board of the clocks when full beam not on and then when full beam is on the clocks circuit board changes on of the neutrals to a live. All of the switching control is in the stalk and is switched on the neutral.
