You say you got a relay box for less than £20! I sell relays @ £1.97 for NO and £2.28 for CO, it must be some sort of relay?

Thanks for help.
PS will take some new photos (when weather permits) and post.

Use of the roof rack mounted lights is illegal on the highway as they above are 1.5m high as Mark found whilst out chasing pigs, pandas and sheep in the lakes the other week.

my D3 has 3 wires from the lights but only 2 in the loom so there is no way to get both functions on my vehicle. It sounds like mine is the same as Craig's D3.
I might be interested in getting both functions to work but I'm not sure what the purpose of the dipped beam is. Can you use this during normal road driving? If not there can't be much use for it as far as I can see.

The 3 wires from the light are - black, white and blue. Blue is power for dip, white for main and black is common.
Andy (macg4) got his dual beams working when the wires were reconnected. Blue at the tiny plug was not connected to any wire in the main loom to the relays.
Looking in the loom to get the dual beam function, you need to check that the tiny Blue wire from the power/mode switch is connected to the main lighting loom otherwise the dual beam does not function. By fitting a power/mode switch in lieu of the power switch later vehicles can be provided with the 2 lighting modes. The lights should all be fitted up to work with both modes.
Lights can be made to come on with either sidelights, dip or main beam by selecting which is the feed source. So if as in Mark's case the lights only come on with main beam remove the feed from main and attach to dip etc.
that would work - 99% of this sort of job is routing the cabling - if you can find a convenient route and gain the same functionality then I think it is a good idea.
I don't know what power rating the lights are but I'm guessing at 60W a piece. 240W in total and that over 12V gives just 20amps. So your 100A supply would be more than adequate.
I found this site for calculating the wire guage: http://www.powerstream.com/Wire_Size.htm but it is american and all measurements are in horse strides, half straw bale weight, and coconut shells or what ever it is they use.
I think I concluded that 4AWG (5mm diameter core) cabling would suffice based on 24ft of cable (crudely calculated on 6ft across the engine bay and 6ft up to the rack and then all the way back to the battery). This gives around 0.3V drop across the circuit based on a 12V supply.
Because I have made many assumptions I would strongly recommend checking with someone who can instinctively say what guage to use!
Something I have just realised is that in wiring all lamps through one relay / circuit you have no built in redundancy - if one faulty fuse, relay or cable will put all your aux lights out. _____________________2005 G4 Discovery
