Spotlight Wiring Harness

Thinking of getting a set of 4 spotlights to go on top of my Jeep.


Had bookmarked some wiring harnesses on Amazon but just realised they say for 2 lights and I can't seem to find any for 4 lights. can you daisy chain them or do I need a specific lead that supports 4 lights?


Also is it an easy thing to install?


Thanks all.

Simplest is to wire 2 lights from one harness,
and the other 2 lights from another harness.



Also is it an easy thing to install?

If it's your first electrical job it's challenging.
That said, the better the kit, the less challenging it will be.


Thanks all.
The digital voltmeter on my car mostly shows low to mid 13vs.
I'm looking towards an external regulator that will give mid 14vs at the bulb.

Normal headlight bulbs are brighter at 14.4v than they are at 13.4v.

Thanks for the info, if I wire up two harnesses can I have them going to one switch or would I need two switches as well?

Can you link to the lights and harness you are looking at?

Depends on the lights and the wire, but yes you could daisy chain them or splice them together.

LEDs do not draw much current, but you still have to think about if you are overloading the wire. A suitable fuse sized to protect the wire would cover you here.

Say your spots draw 2A each. 4 spots X 2A = 8A. Then you have to add in the length of your wire run from the battery ... say it is 15 feet. You should probably use a 14awg wire for that to carry the current and minimize voltage loss, if you put all the spots on one wire. So if the harness you want has 14awg wire or larger, I would say go ahead and daisy chain them.

I am building my own light harness right now using a combo of 14awg for the little lights and 12awg for the big one.

How many Watts is each light?

These are the lights I am thinking of:


https://www.amazon.co.uk/dp/B01KRV3P...v_ov_lig_dp_it

Nilight LED Light Bar 4PCS 4 Inch 18W LED Bar 1260lm Flood Led Off Road Driving Lights



All the harnesses seem to be the same, just different brand name and price, one example:


https://www.amazon.co.uk/dp/B07P8XDZ...v_ov_lig_dp_it
WOWLED Driving Light Wiring Harness, PVC Wiring Switch Relay Fuse Kit for Connect 2 LED Driving Work Light 4x4 Truck




Hope that helps.

Only 18w for the ones I was looking at.

If you want all 4 lights to come on at the same time, from the same switch, then one kit will work. Just splice in connectors to go to the second pair of lights. The wiring kit says that it is rated for 240 watts. That will quite easily handle the 72 watts (18w per light X 4) of the 4 lights that you want to mount.

If you want to be able to switch each par of lights individually, then you will need 2 wiring kits.

You can daisy chain those harnesses to run those lights. If you get a full combined 18W out of those lights, that is only 1.5A. No worries. Going to take some splicing though.

Next question.

Have you got the skills and the tools to run two lights from one switch Oj?

If not, well 2 switches side by side by side are pretty easy to throw at the same time.
Much easier and simpler to wire up to.

There's another point of view that says the smart man would prefer two stand alone system.
The idea there is that if one circuit goes down, you've still got the other one working.
I know which system I'd go for.

Honestly I don't think I want to mess around splicing when I don't have to, as you say, two switches would be easier and hardly an inconvenience to use.
Thanks.

Thanks.
I think 2 separate circuits would be easier, smarter, and hardly any inconvenience to use OJ.

If the one harness has a relay going to the two lights then you can use one switch but you need two relays

Any special reason for needing individual spotlights? Don't mount the lights above your windshield, it only makes a bunch of glare for the driver. Just mount a led light bar on your bumper, it's easy and you are done.
