How does that work then

[ibexman]

My headlamps have only a normal 3 spade plug but when u switch on side lights the headlamps are on too although there is no extra lamp in the bowl ????

Dim dip I assume.

no on with sidelights

As Peter says - "Dim Dip" - the dipped beam filament of the headlight is fed with a reduced voltage, (via a resistor) when the sidelights and ignition are switched on together.

It's a three-stage system for the headlamp.

Dim - On but dimmed, with sidelights

Dip - On (nearly) full power, but dipped down and to the left

Full - On full power straight ahead.

200Tdi are fitted with it, at least mine is

some of the last TD's in CSW trim had it too, no longer a legal requirement for UK.

As said, it's dim dip on he TD5. Controlled by a pink relay behind the dash.You can remove it and (apparently, I haven't yet done so, but it looks right from the wiring diagram) short pins 2 and 8.
