Thread: Spotlights wont dip off with high beams "2"

Hi sschmez, if you have the set up still in place, start by disconnecting the two light blue wires from the headlight sockets and connecting both wires to ONE of the light grey wires going to your headlight relay.

Next, same with the yellow, connect the yellow wire coming from your driving light relay to the green wire on the SAME headlight relay.

Try this first, it should work. If it does, come back and I’ll explain how to put a switch in, as required by law, if you want it.

Cheers.

PS. You don’t need any diodes. The only time diodes are used is to suppress voltage spikes that occur when a relay coil is de-energised and most automotive relays have some form of suppression built-in and usually not the diode form.

thanx Drivesafe

the whole assembly is sitting on the bench beside me, so I'll have to give your suggestion a try one night this week.

do you suspect over engineering ?? ... I was just aiming at failsafe.

No, not at all.

I have never wired up the way you have and this is not meant as a criticism, I just don’t do it that way, picking up the driving light feed separately, from the second set of headlight sockets.

I always use just the one socket for everything. It simplifies the wiring.

BTW, I am assuming that your diagram of the headlight socket is as viewed from the wire side and not the terminal side.

Cheers and let us know how you get on.

I agree with drivesave but I would say it in a different way.

1. Looking at your diagram cut the yellow and light blue wire that
connects to left car plug H1
2. Looking at the driving light relay (the middle one) connect left side
light blue wire (the one you cut) to the other light blue wire on the
right. Job Done.

Hope I not confusing things.

thats an interesting way of wiring things up.....
it takes advantage of having the two fuses (left and right hand side lights)
if one should blow you still have lights on one side....

but a bit of extra wiring compared to how i would have done it.....

(i would have only taken a feed to energise the pull-in solenoid in the relay....
it appears you are also getting the earth from the headlight plug...)

Hi Zook, sschmez’s relay coils only, are being powered by the original headlight fuses.

These dual relays have fuses in them and all the lights are now powered direct from the battery.

Cheers.

i realize that....what i meant was that the earth has been run back to the headlight plug as well.....
the earth for the coil.....i dont see the reason for that.....
nor do i know exactly where it earths to as it runs back into the harness.........


i think that setup should work perfectly if the earths for the relay coils were
run straight to chassis earth rather than the headlight plug.....

Hi again Zook, if you have positive switched headlights then you can simply earth one side of the relay’s coil.

If you have negative switched headlights or if you don’t know whether your headlights are pos or neg switched, you can wire them up this way and it doesn’t matter what polarity they are, they will still work.

That’s why I up graded the original Headlight Project to this new one.

It is much simpler to fit and you don’t need a multi meter to try and work out what wire does what.

Does that help.

Cheers

BTW, thanks to incisors help, I will be posting the details of the new Headlight Upgrade Kits tomorrow.

Inc installed a test kit this evening to test both the kit and the instructions and with a few simple additions to the instructions, the kits are now available and I will post some quotes from incisors PM to me.

He seems very happy with both the installation and more importantly, with the very noticeable increase in the brightness of his headlights.
