This question is for Mustangs having the factory HIDs fitted only. This probably only refers to 2011 and newer? Please don't answer if you have non-HID halogen headlights or aftermarket HIDs:


What do your HIDs do when you pull the multifunction lever rearward, toward the steering wheel when the headlights are off?


On my car the HIDs flash for a split second but do not stay on, even if I am holding the lever. Shouldn't they stay on until I release the lever?

If the head lights are already on, pulling the multifunction lever rearward turns on the high beams and they stay on until I release the lever as expected, and the way they work in every other car I've owned.

What does yours do?

From workshop manual:
The flash-to-pass feature is unique for HID -equipped vehicles. If the low beams are off when the flash-to-
pass is requested, the HID ballasts and the shutters within the headlamps are activated for less than 0.5
second. If the low beams are on when the flash-to-pass is requested, the shutters within the headlamps are
activated as long as the multifunction switch is held in the FLASH-TO-PASS position.
It looks like it works as designed, lights up for about 0.5s
So, this feature is useless...

I’ll check tomorrow Jeff, but I’m think mine stays on for as long as I hold the lever back, just as you report yours do when the headlights are already on.

If you are correct, and it does work this way, it’s not useless. When I have the need for this function, I generally click the lever several times anyway in quick succession. At 0.5s per click, that’s plenty.

I don’t think Jeff was necessarily complaining about the behavior, but rather asking if this were normal for the car.

Just checked mine. HID factory option on my 2011. Lights off has a half second high beam flash. Even holding the lever back. With headlights on, the head lights stay on high beam for as long as you pull back on the lever :)

Thanks David, due to some unforeseen circumstances, I’m out of town and didn’t get a chance to check this out on my car. My apologies Jeff, I’ll still check it out on my car when I get home.

Both my 2013 F150 and 2013 Mustang give you the 1/2 second flash, which when I have actually used the Flash to pass is about twice as long as I leave it on. Never thought it was a good Idea to blind someone you are trying to pass, Just saying.

I have only used my flash to pass to warn on coming traffic, they are headed toward a 'speed trap'. :)

2014 - Factory Installed HID
Lights off, lever back = .5 High Beam Flash
Lights on, lever back = Continuous High Beam until lever is released

I use mine to tell a passing Semi, he is clear to pull back over in front of me.

I also use them to give a friendly Nod, to approaching Mustangs traveling in the opposite direction.
