Outer Limits 4x4 Board

I have almost completed the installation of a set of Hella 4000's on my 2000 Triton ute (excellent early Xmas present from wife ) . Using a Pirahna wiring loom. All working ok - but what on earth is the yellow wire out the back of each light to be connected to? The brown wire is positive and blue is earth. Yellow...???? The lights are working, but the yellow wire must be for something. Hella wiring diagram doesn't help.
Is a 25 Amp fuse sufficient
I have one pencil and one spread - should the spread beam be on the passengers side to light the edge of the road - or doesn't it really matter.

Thanks for any help .

isnt the hella rallye 4000 got the swtichable wattage in the light? like a high and low beam spottie??


i thinks like 100w/170watt or is that only on the IPF lights?


thats wot it is for i thinks if not sorry!

i don t think the 4000 was a dual wattage, but i could be wrong with the new ones. Lots of lights i have seen though have a grounding point inside the housing which the bulb can be connected to, but sometimes the bulb is connected directly to a grounding wire that just exits the light at the same point as the positive wire. they could both be grounding wires, but only opening the light to make sure, will give you an answer you can rely on, and they are seriouly not that difficult to open to change the bulbs.

Thanks for the feedback guys. I have completed my installation and can report that the yellow wire would appear to have very little use. Put it this way... my yellow wires did not get connected to anything, and the lights are working fine. In fact they are awesome.

Perhaps as the general suggests, it may be for grounding. However it does not connect to anything inside the light itself. The way the 4000s are set up is that there is a "mini loom" that plugs into the back of each light and which is then connected to the main wiring loom. The mini loom has the 3 coloured wire, blue, yellow and brown. However the corresponding plug on the back of the light only has connections for two of the 3 pins - there is not an equivalent connected pin for the yellow wire of the mini loom. On the mini loom, the Blue is the positive and the brown is the negative. But I guess you should check yourself each time as they might make changes in their packaging.

Well I guess that was as clear as mud, but hope it helps someone. Maybe one day I might find out what the yellow is for.

Thanks once again for the help

In the info that came with mine said to cut the yellow wire off.
This I have done and they work a treat.

To save on costs they use the same wiring loom for a number of different lights. They just use what they need out of the loom for each application.

are these the new raylee 4000s with the led ring around them ? IF SO THATS WHAT THE OTHER WIRE IS FOR

That's funny. The exact opposite to 240V mains wiring.

I thought it was something to do with europeans that yellow wire so i did a google and found this http://www.rallylights.com/hella/4000.asp

The lamps have an integrated weather-proof plug for the electrics. The internal connections are already wired. Note also that there are three wires! The third wire is for an integrated parking lamp (Driving Lamp only). This is a European feature that has been carried to the US. The wiring harness was designed specifically for this lamp and the switch operates the city light independently.

Well done Tooheys!!!
Finally I have an answer to the mystery.
No mystery on their performance and ease of adjustment. They are awesome.

For a 12V incandescent globe I don't think polarity really matters...
