Dim Dip Removal

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....

Have you tried pulling the plug from the dim-dip unit?

Just unplug the connector on the resistor (small gold unit on N/S bulkhead), worked on mine

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.

No dim dip = no MOT.

My disco is the only car I've had with a dim-dip facility, my old RRC didn't have it and the D2's are not fitted with it.
There is nothing in the MOT Testers Manual referring to vehicles fitted with dim-dip.

Yeah I always wonder what it's about.

Obviously it is to make the side lights brighter, they must be too duff on their own, but I don't reckon it would be an MOT issue, it will have been to get the cars through type approval when they were new I reckon.

Cheers

dim dip not part of test unless fitted, another one of the silly arse rules. disconnect it and it cant be tested..lol

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....

I thought u had a 200 after looking at one of your previous posts.

nah, the 200 went 3 years ago now, had a v8 since then, before getting the current 300 last april

If I remember from the handbook the DimDip is not used if the landy has headlamp levelling which mine has (1995 300tdi ) but the actual resistor is fitted to the bulkhead
