Wire sizes

[thinfourth2]

I have a landrover and as all offroaders i have this nagging feeling it needs more lights

Is there a nice little guide for working out what size of wires i need for wiring up the lights

Phone Gemm 4x4 and ask them.

They are based in Larbert near Falkirk. Their business is building, maintaining and providing parts for landrovers. If they dont know the size of wire needed no one will.

Best approach is to fit a relay to switch the new lights and feed them directly from the battery with some decent cable.

P=IV so divide the total wattage of the lights by 12 to get the current. Then I would go for cable that can take that current x 1.5 or so.

e.g. 2x55w spots = 110w divide by 12 is approx 10 amps. So 12-15 amp cable will be fine.
