Adding Lights

Is it a drama to fit an accessory lightbar around 23in to a 150 Kakadu on an ARB bar with HID mains as I see it is not possible to use the plug & play wiring looms supplied with some lights that piggy back off normal globes high beam. As it is compulsory for them to only operate with high beam I cannot wire them from scratch with a relay and switch off the battery.
Some of the lightbars coming out now seem to have an advertised wattage of 336 to 648 for a 23in that would need a wiring loom like jumper leads & even a 60A relay would have no safety margin.

Lightbars are LED technology. They draw less amperage than a halogen globe. Even a halogen globe using the old rule of thumb that @ 12volt, 100watt (96 in reality) = 8 Amps puts a 648 Watt Halogen at around 52 Amps.

What amperage do they say a 336 to 648 LED bar draws? I'd think it would be less than 20 amps.

I might chuck a multimeter on mine and see what the draw....

Hi guys,

I have been considering the same scenario with a roof mounted LED light bar that was rated at 420W, which would mean some very large wiring running down to the engine bay from the roof. Did anyone have any luck finding out actual current draw on these light bars?

light bars run at a lot less than the rated wattage, If you run LED's at 100% rated power they will only last 100 hours or so before degradation is noticeable. Most if not all lightbars will draw about 3-5% of the rated wattage, I have a 320W that draws 11 amps.
