Anyone know how to remove the dim dip system on a 94 disco? mines starting to take a second or two before the lights come on these days, and i don't want to be stuck too far from home with no lights....

Correct if the OP's disco is a 95MY 300 series but it's a 94MY 200. That's what i have done as I have LED side lights and they look naff with the dim-dip working.

Why have a dim, as always the answer is on the web, and as always lots 
this is only some of it.
The dim-dip systems were not intended for daytime use as Daylight Running Lamps DRLs. Rather, they operated if the engine was running and the driver switched on the parking lamps (called "sidelights" in the UK). Dim-dip was intended to provide a night time "town beam" with intensity between that of the parking lamps commonly used at the time by British drivers in city traffic after dark, and dipped (low) beams; the former were considered insufficiently intense to provide improved conspicuity in conditions requiring it, while the latter were considered too glaring for safe use in built-up areas. The UK was the only country to require such dim-dip systems, though vehicles so equipped were sold in other Commonwealth countries with left-hand traffic.
In 1988, the European Commission successfully prosecuted the UK government in the European Court of Justice, arguing that the UK requirement for dim-dip was illegal under EC directives prohibiting member states from enacting vehicle lighting requirements not contained in pan-European EC directives. As a result, the UK requirement for dim-dip was quashed.
Nevertheless, dim-dip systems remain permitted, and while such systems are not presently as common as they once were, dim-dip functionality was fitted on many new cars well into the 1990s.

dim dip isn't required anymore, as per the post above. the original sidelights still work in conjunction with the dimmed headlights anyway.
i will try unplugging the resistor first, and it's a '94 300tdi....
