Light bar wiring,have some questions.

'Ive ordered a light bar and 4 18w led spots.

Am i best using an inline fuse or one of the relays with the fuse built in?

I want to use one wire each for the +- rather than having to route loads of wires, will 6amp wire be ok or should it be a little over rated?

cheers

I done mine with 1 wire. I put a inline fuse in and a relay

Not over rated but on the limit.

you should overrate it, but you'll find even the small 1mm core is just shy of 9amps..

I bought this wire and inline fuse holder.

Surely better to provide individual inline fuses after the relay, before the light.
That way, even if a fuse blows, you have some light.
Cheers

Mines gone from light bar to relay then inline fuse then battery

Not seen anybody use four separate fuses, i only need a four blade relay too so ill order one of those today.

Whats the best way apart from soldering to join the wires from the spot lights to the main wire?

Only one other way with vehicle wiring and that's 'crimp' with connectors to suit the application.

Decided to get one of these instead.

Also one of these. Will 7.5 amp be ok? It was the closest i could find to 6.

presuming you are replacing the 30a with the 7.5.. then yup will be fine. i'd also slap on silicon grease or vaseline to all joints to help weather proof

Yes i will be swapping it

like the look for those resettleable fuses

Im going to change the one for my electric fan to one.

What wattage is the light bar?

See post #1, 4 x 18 watt lamps.... that makes 72watts in total.

First post say light bar and 4 x spotlights

Oh sorry you don't mean an led light bar and 4 spots. A bit of metal and 4 spots.
