I never knew they existed, but they sound like a great idea.Does anyone have an idea about installing the rear fog light(s)?
It is not listed as an option when I purchased the Ascent, however I found the reserved indicator above the speedo meter..

According to the article I linked to above (I have not checked accuracy of law reference), only one is allowed in the rear in the US.Yes, I installed a set. They replace the reflectors in the rear bumper.
I wired mine into the trailer hitch wiring.
As for or the dash light, there is no way to activate that without at a minimum new software, a new switch and wiring harness.
can you please link to the specific fog light product you purchased. Was this fog light the same as what is used in the front?Yes, I installed a set. They replace the reflectors in the rear bumper.

S6.1.3.6 Auxiliary lamps mounted near identification lamps. Each auxiliary lamp must be located at least twice the distance from any required identification lamp as the distance between two adjacent required identification lamps.
and
both seem to allude to the same thing. There is no SPECIFIC requirement for rear facing fog lamps, however there are a couple of mentions of "auxillary lamps" which must "be on when the vehicle's headlights are on in a steady state". Take that for what you will.
As for the article mentioning the european automotive exec making that statement, that could have been in reference to some sort of import clause on foreign vehicles, but I can't seem to find the letter of the law.
Having an '04 Saab, I can verify that it came off the boat with rear facing fogs on both sides, and one of the bulbs was removed...but when I snapped a second bulb in there (to satisfy some BS pennsyltucky inspectors power trip) it worked just fine.
I brought up this issue with Drive Radio this morning and John Rush stated that he thought the modern rear lights and reflectors are vastly improved than previous years that he did not believe it was necessary to assist others seeing our vehicle in fog or snow white outs. I have not tested this out yet. I did notice the difference in the photos linked above but I do not know if those photos represented modern auto lighting.Yes, I installed a set.

Right, I saw that...but that doesn't specifically identify directionality or even the number required - or limited to.S6.1.3.6 Auxiliary lamps mounted near identification lamps.

Have you by chance actually tested the visibility with day running lights on and the reflectors from the rear during fog or white outs (day and night)?Right, I saw that...but that doesn't specifically identify directionality or even the number required - or limited to.
The NHTSA chart doesn't either, as I saw.
not on my subie and not pertaining to this issue at hand, but i've done more than enough testing for GSA Spec. (KKK-A-1822) as applic. to emergency vehicles - in regards to driving and emergency vehicle lighting in all conditions, both in design and proof-of-concept.Have you by chance actually tested the visibility with day running lights on and the reflectors from the rear during fog or white outs (day and night)?
I live in Denver so I am interested as well. I would be interested to learn which specific product you choose. I figure it can be wired into the front fog light switch, although I have no idea how this is done.not on my subie and not pertaining to this issue at hand, but i've done more than enough testing for GSA Spec.

Reflectors are maximally effective with directional light, so I'd take an active set of lightheads over a passive set of reflectors in a whiteout or fog conditions. And when the time permits, I plan on getting a set of active rear facing fog lights on my ascent - as we see plenty of snow up here.
IJDMTOY.comcan you please link to the specific fog light product you purchased. Was this fog light the same as what is used in the front?
I understand they areinstralled where the rear reflectors in the bumpers are but I do nto see why they would be wired to the tail lights or any other point other than the switch for the front fog lights. I would not want these on all the time but rather only when I turn on the front fog lights. The link to that product does not indicate it fits the Ascent.IJDMTOY.com

No not the same as the front. They replace the reflectors in the rear bumper.
Low mounted lights are easier to see in heavy fog. That's why front fogs are mounted low.
They fit the Ascent perfectly. The Ascent reflectors are the exact same part number as the cars listed.I understand they areinstralled where the rear reflectors in the bumpers are but I do nto see why they would be wired to the tail lights or any other point other than the switch for the front fog lights.

I have to figure out if it is legal to have two of these lights on when headlights are on. Thanks for the clarification. I will also explore LED fog lights for the rear reflector replacements.They fit the Ascent perfectly. The Ascent reflectors are the exact same part number as the cars listed.
I like having them on whenever the headlights are on.
These are not high intensity leds, they are about the same brightness as a trailer tail/brake light.
My wife commutes on I66, and on that road, every bit of extra light helps keep you from getting rear ended.
