Fog light lens haze
#41
Please notice that the PIAA 4064 light that was listed is a driving lamp and not a fog lamp. It only has a 30 degree beam spread whereas fog lamps have a beam spread of greater than 90 degrees. Replacing a fog lamp with a driving lamp will be useless in foggy conditions. The fog lamp has a lens that cuts off the beam at a certain height just like your low beams, this reduces reflected glare back towards you. A driving lamp with a 30 degree cone is just that, a complete cone with no vertical cutoff, and since they are rated at a higher wattage they will reflect a lot of light back at you. If you use it to replace your fog lamp and then hook it up to existing wiring then it will only work with your low beams as that is how the fog lamps are wired. Unfortunately driving lamps are designed to compliment high beams and not low beams.

Converting the existing wiring to control driving lamps rather than fog lamps may be complicated or may be simple. It depends on how the dash switch is wired and how that switch is internally programmed. On older vehicles with a seperate fog lamp switch, you could remove the low beam feed wire and replace it with a high beam feed wire. I don't have any Mustang documentation or schematics yet so I'm not sure how you could modify this system. If it doesn't rely a lot on the smart box then it should be a simple mod.
I've been talking with several of the aftermarket sequential taillight manufacturers and have discovered that the '07 wiring differs from the 05-06s and relies more on the smart box for certain functions. Once I find a good maintenance CD with wiring diagrams I should have a better understanding.

My guess is that the relay is so you wire power directly from the battery to the H3 bulb. Ford already does this at the factory, so I am unsure why they needed to include another relay.

Nah.
Still I agree completely they were not designed to be driving lights they were really put there to enhance the design cues of our Stangs, still you should be able to use them as you see fit without consequence.

Just thinking.
Okay,Lets say I never need foglights (I don't) or I can install additional ones.
If I use the PIAA set-up and original wire signals to their relay, can I just switch the headlamp wires so the high beams come on with the dash switch?
Wouldn't the low beams come on with the stalk switch?
Wouldn't the fogs (driving lights) come on with highs only?
Would the smart junction box still be happy?

I removed the terminals from the headlight harness and switched them.
My headlights now come on with highbeams and I can turn on the fogs.
Of course, to turn on the lowbeams I have to flick the stalk switch (and the dash indicator for the high beams comes on).

Another hazer here. I had her into the dealer today on an unrelated issue (one which I'll document once the dealer is able to) and while there had them look at both the fogs for hazing, and the headlights for tiny cracks that had developed in the centre of the covers. Both fogs and lights are being replaced under warranty.

That "hole" in the back is a vent. You plug it up and the rear of the housing will melt over time. I did that very thing to a fog light in our Escape and guess what - the housing started to melt which was great fun because at the time, Escape fog lights from Ford were $90 each
