inside indicator -- There's a green light on the dash that lights up when the aux lights are on. At least it's supposed to. The shops commonly forget to turn it on....

And no, you can't turn on the Aux lights without having the headlights on. At least not if you're using the factory wiring....

What's really cool is that once you get them to turn on the Aux lights, you don't really need to add additional lights as the ML has fog lights built into the headlight assembly. All you need to do is to add the bulbs!

Of course, I found this out after I had the brush guard and fog lights added. I was told that the dealer doesn't tell you about this as the built-in fog lights are illegal in many states as they are too high off the ground...
