::WIRING:: Roof Mounted Spot Lights

Evening All,
As you may know, i've recently (and successfully) mounted all 4 spotlights to my roofbar.
If you haven't seen my previous topic, i basically made up a set of brackets that clamp on my roofbar as drilling through it is not an option.



I was hoping someone could tell me how i would go about wiring them up.
I've got the appropriate cables, switch, tools ect. I just need to know:
-How should i make the circuit from light to light?
-Where should i feed the wires?- to and from
-How should i hide /secure wires from weathering ect.
-Where's an easy place to put the relay switch?
-What fuse do i pick up on?
-And also any other helpful tips & tricks !

If i can get some support before next weekend, i would be extremely grateful. :blush:

Thanks all,
LB

You could pass them through the antena radio socket at the top of the car above drivers door. No drilling required just a small and tight cut to fit in the cable.
After that you pass it the same way antenna cable goes until down to the drivers pedals. Simple , easy and smart.

Also if you want to go at the back you can pass them through a tiny gap between rear back lights and door. Its the spot that the rear light meet the door.

Hope you understand. Iwill try to find picks and upload for example.

The first one is done by me cousin and the second one by a friend of mine.

The key question is, how powerful (in watts) is each lamp. This will determine your wiring options.

Assumming they are 50 Watts, each one will draw just over 4 Amps when running.

I earthed each of mine separately to the light bar itself. To do this run a short wire from each lamp to the lamp bracket. This wire needs to cope with the current of one lamp.

For the live feed you have to look at what current you need to cover
Based on 50 Watts you have you then have to cater for up to 16 Amps of current draw. This may determine whether you run them as all four together (16 Amp wiring) or as two pairs (8 Amp wiring) . I run mine as two pairs.

Daisy chain the live feeds for the sets of lamps you wish to group together and run the live feeds to relay(s) under the bonnet, one relay per live feed.

Run a fused live feed to the relays from the battery.

Now the mind bending bit. Jimny lights are "live feed" and earth switched. Therefore when the lights are on the Suzuki switch completes the circuit by earthing them. Therefore you also need a live feed to the switching contact on the relay. Connect the headlight switched earth to the earth of the relay.

Yeah ! Thanks
I had considered that.. because it's obviously nice and close to the rooflights... and almost underneith the bar.
Plus.. My original aerial was... 'ahem'... removed. (damn clothes line!)
So i figured i could just use that hole and mount the new aerial elsewhere.
Thanks again !

I'm in the same position here so the info is usefull. Wiring is one area that i'm not confident in, but i'm happy to have a crack at it and take my time.

Ideally i would like to run them through a pair of 3 way switches so that i have off/main beam and roof/ just roof and then ideally the outside pair together then the inside pair together. How hard is it to achieve this? I plan on using the pre wired wiring kits and 1 per pair of lights and presumably extending to the roof.

However for simplicity i may wire them into their own switch seperately.
Do i then just need to take a live fused feed from the battery to the relay then to the switch or will i still need to take a feed from the lighting/ignition?

Apologies if i'm being a bit simple. It may make more sense to me in the morning :S

AAAnnnd another question. Hows the standard battery and alternator cope with the extra load? I'm also adding in a cb too shortly. Feels like mines already struggling with everything on lights/heater/rear screen/wipers etc....
