Question about ON/OFF button and feature

Obviously still getting to know my 2003, and got around to playing with the buttons just below my climate control knobs.

From the left, the first two are for my rear defroster and rear window washer fluid, and the next is to turn overdrive off. Is the far right ON/OFF button factory?

When in the ON position, the front headlights flash rapidly (a few times a second), and alternate sides so that when the driver's side is on, the passenger side is off, and vice versa. What would this be useful for? Emergency situations?

I'm gonna inspect under the hood to see if I can find any new wiring to the headlights, but thought maybe some of you might be able to shed some light on this, or at least tell me if it's factory. Thanks!!

It seems like you have a headlight modulator. Fairly common in motorocycles(aftermarket) and emergency vehicles and the purpose is for greater visibility. Just check your state laws as they are illegal in many states and countries.

My guess would be that your Jeep was previously owned by either someone who was an emergency responder or someone who liked flashing lights.

In answer to your question, no this is not a factory switch.That space was generally left open or in the Rubicon it is where the Axle Lock switch was placed.
06 Rubi with some sort of double ended, chrome knobbed, cross threaded, infinitely adjustable, frequently breakable, worn out flammywhammers zip tied onto it.
It used to be a jeep thing... til that sh!t broke!

That's the flux capacitor. The lights were building charge to activate. Hit 88 and report back what happens.

Like has been said, not OEM and probably illegal for civilian use. On the up side, follow the wires and you have a switch already wired in for extra lights.

Gotcha. Searched for headlight modulators on youtube and that seems to be what it is, only not on a motorcycle.

I've got some off road lights I pulled off my Ranger before I sold it, and was thinking of mounting those on a bar hoop on the front bumper. This switch would be a sweet way to operate them!

I do kind of like the flashing lights though .. but yea I'm sure they're illegal for me to use. I'll try to post a video of them operating just for y'all to see before I disconnect anything.
