Wiring for spots.

(1/7) > >>

Andy.:
Ok I need some advice please.

I have two front fogs (in the front valance), two spots on the A bar and 4 spots on the roof which I need to all wire to three seperate switches.

The fogs and A bar spots are already wired to relays in the engine bay then they each have a wire taken into the interior where they used to be switched.
The roof spots are the same, relayed and wired in.

All the new switches have little bulbs in them, where do I get the power for these from?

The roof spots are hard wired into a main light feed from the steering column, as are the front fogs.

So what I would like is any wiring diagrams anyone has to help me wire these up.

hobbit:
I'm presuming the switches have 3 connections on them, if so 2 will be for the feed in and out and the 3rd should be for an earth to complete the circuit for the warning light

Andy.:
They have two wires going to the switch part and then another two coming from the light feed.

Here is a pic of the switches that I'm using.

Range Rover Blues:
They look like RR ones :D

If you've got 3 switch and 3 sets of lights? I took the power for my fogs from the sidelights, actually the backlights before the dimmer resistor!  The main beams obviously from the high beamcircuit and the worklights I'd suggest from the sidelights also.
I've used a diode or two to make my fogs come on with my main beam and plan to do the same when I get some roof lights.  the wiring isn't difficult except that you don't get much space.

On the Disco I've got.....................

Two 130 watt Procomp spots on the A-bar that are powered from the spare battery through two relays, one per light, and triggared from the main beam switch.

Two roof mounted 55 watt spots off the spare battery using one relay and the same triggar as the Procomps.

Two roof mounted Britex twin bulb floods (2x55 watt bulbs in each) again off the spare battery with a relay each and triggard off the dip beam.
Both sets of roof lights are connected to a switches on the dash so you can choose what to have on.  :wink:

The floodlights give about the same beam (only a bit wider) as the dip beam headlights and have the advantage that you can still have them on so you can see should the headlights get covered in mud or when wading at night, yet you don't blind the driver in front!  :D
