Do you have some links to those lamps & aux lamps?

The headlights are Wisamic 5-3/4 5.75 inch LED Headlight x 2.
As per the description, they say each has 9LEDs @5W each on low beam.

The Aux lights are Rigid Industries 262213 D-SS Series Pro, 3 Inch, Spot Beam, LED Light, Pair

Spec says 45W. Not sure if the 45W rating is for the pair or for each. These pods put out amazing amount of light. These are mounted on the front crash bar.

Picture of riding fairly rough roads at night with the RIGIDS :)

I have no first hand experience of Wisamic - but the LED's are Osram - Stable, long-lived but not wildly efficient. Prepared to believe 45W consumption but not huge lumen count. Fret not - Audi think the same. imo a better choice than highly efficient but "rapid to gate down" CREE.

If that is your idea of "fairly" rough - you're on your own on "grab-a-granny" nights out.

Rigid are good quality lights, built for rough off-road use.
While these #263313 are just 3"X4" in size, two of them put out less usable light (1304lx @ 10m) than a single #178713 10" bar (3880lx @ 10m).
Using the inverse square rule:
r=Sqrt E/I
#263313:
r=Sqrt 13,040lx/3.2lx
r=63.84m or 209 feet
versus -
#178713:
r=sqrt 38,800lx/3.2lx
r=110m or 361 feet

I reckon to get one of these Rigid #178713 to mount under my headlights and then do actual light measurements to compare to my Clearwater Erica.
 
I probably should explain the inverse square rule further:
E = illuminance , measured in lux, is the light output.
I = intensity , measured in lux, is the amount of light falling upon an object.
r = slant range (steradian) is the distance in meters.

If the E (illuminance) at 1 meter is known:
r = sqrt (E ÷ I)
Light needed for human detection and identification of an object of neutral contrast is 3.2 lux.
Therefor, r=sqrt E ÷ 3.2

Yes, that's what I was saying:

Yes, a Hall clamp would indeed be correct tool for that application - didn't consider you might have access to one and I didnt see that link you posted originally? (AC current clamps are of course much more commonplace). It would great data if you can get that - standing current without lights would be nice to see.

I got the meter that use the hall effect loop. put the loop around the wires from the +ve terminal.

Following are the readings (current draw):
All bulbs are LED.

IGN ON/ Engine OFF
  • Headlights/tail lights ON: 4A
  • Headlights/tail lights ON, RIGID AUX Lights ON: 12.5 A
ENGINE ON, IDLE
  • Headlights/tail lights ON: 4A
  • Headlights/tail lights ON, RIGID AUX Lights ON: 3.5 A

Do I have room to add 150W load ?
 
Well here's the problem - when the engine is running, you are not measuring all the current, because it's not coming from the battery, but the generator. Indeed pay attention to the current direction as to whether it is flowing INTO the battery when engine is running (which you would expect it should be)

Your numbers are pretty suspect anyway given, with ignition off, your 2x45w headlights are drawing 4A while your 2 x 47 aux are drawing 8.5
