Fog lamps: Where to buy wire in DIN standard colours?

[silverbullet]

I'm finishing off doing a retro-fit fog lamp conversion to the 1995 SA and need to source a suitable length of light grey/white trace, 1.5 mm sq. (twin fog lamps for good measure) to run from the engine bay up to the relay board, since the Big Window buses don't have that line in the loom.
No point raiding an old German-made loom as the fuses are on the rhs in the SA, the wires won't be long enough even if rhd.
Any ideas of where I can get a 10m roll in the correct colours?

PS Oddly the 1990 small-window SA-built bus does have a fog-light feed out to the engine bay junction box, but no wire in the tail-light loom. That was a lot easier to sort out!
