And here's my second question for today....

I believe the photos identify as the dim-dip that was fitted on some cars. They never had any of this new fangled stuff when I was young....
The general consensus, I believe is to by-pass it.

Any body done this, and how do you do it please?

Thanks again - you're a helpful bunch!

i think you can just cut the green wire to the relay, thus turning it into a non dim-dip car...

[Hikari Warrior]

Just giving this a nudge....

I'm sorting wiring out today, and just hoped to be able to confirm exactly what is needed to by-pass the dim-dip.
I do like the idea of just cutting the green wire - seems quite simple!

Thanks

Isn't dim dip like an MoT requirement?

[Guess-Works.com]

No, never came into legislation...

Depends if you want to remove the unit completely or just remove the power feed to the headlights when the side lights are on ( this is what the unit does )

If you connect the Blue with Brown trace wire to the Blue/Red wire then the unit becomes completely redundant, if you just cut wires then you will still need the unit, without which your headlights won't work.

Or just unplug the resistor on the wing.

seconded on unplugging the resistor.

Its thats simple.

If you don't want to cut any wires or remove any components then just remove the fuse. It worked for me.

Just cut the green wire .......it's that simple.
This is speaking from personal experience on 3 cars with this relay.
If you could also get someone to stand beside you with a 60 second countdown clock while you do it........it really makes the cutting of the GREEN WIRE much more exciting.

I wouldn't say it's the concensus to remove the system at all, lots of people do but I don't imagine it's the norm. For one thing it does quite a useful thing and if the EU make the requirement for day running lights retrospective might become more useful still. People have to remove it if they have LED sidelights fitted or Angel Eyes but for most of us it's just fine to leave it there. It did enter legislation, and was a legal requirement but the EU decided after a complaint from some major manufacturers that it had never been legal for the UK government to make it law. Personally I see no point in removing it.

Sorry to revive such an old thread. I never knew what this system did and have realised it doesn't actually work on my car.

So to simplify fault finding and a clean engine bay is like to remove it all.

If I remove the resistor and relay and connect the 2 wires as per Guessworks post is it simply a case of following back the remaining wires and removing them completely? Where do the remaining wires go ?

Thanks

The reason I prefer to remove them, joining the blue-red and blue-brown (which is essential) is that failure of the relay, which is quite common, can cause sudden loss of dipped headlights, and a possible accident. You are safer without it.

 

Just insulate the other wires so tehy can't short. No need to unpick the wrapping of the loom to get the wires out.

Since my last post on this thread, i now agree with Tiger99, in the past couple of years, i have had many customers with lighting problems and it is usually caused by the dim dip relay. I now, as a matter of course, simply remove the relay and join the said wires together before even trying to trace any faults and nine times out of ten, the fault is gone as soon as i join the wires. There is no real need to trace the other wires back to remove them. Just insulate them and tuck it all out of the way. or you will be pulling a lot of loom apart for no real gain.

Sorry for the thread bump but i found a picture of what i removed:

It turned out my system never worked because the inline fuse was all melted.

sorry to revive an old thread... been chasing a lighting fault for 2 days and it turned out to be the dim/dip relay.

after creating a shorting link with a wire and some spade connectors its all working fine. 

 

my question is how safe is this? i cant find anything for an MoT requirement. how common is it to bypass this? thanks guys!

Perfectly safe to bypass!
