Headlights saving MPG??!
Anyone want to explain how these save me fuel? Maybe it will be worth it.. like my Tornado Fuel Saver and the fuel line magnets that align the fuel molecules.

The Environmental Choice in Automotive Lighting
With million upon millions of vehicles around the world on the road both night and day, the need for safe and effective automotive lighting is an undeniable necessity. Yet the equally clear realities of ever shrinking resources worldwide, higher energy costs and environmental impacts linked to human actions demand a balance between the needs of drivers and responsible stewardship of the environment for current and future generations. Thankfully drivers looking for a green alternative today can achieve just such a balance with Sylvania EcoBright headlights.
Sylvania EcoBright headlights are designed from the ground up to provide drivers with excellent down-road and side-road visibility with a brightness rating that is 25% higher than an aged standard bulb. EcoBright bulb's low operational wattage also allows for energy conservation, resulting in the use of 9% to 21% less energy than SAE maximum design specifications. This decreased use of energy by vehicle electrical systems leads to monetary saving in fuel, estimated between $2 - $19 over the life of a pair of headlight bulbs, which in turn equates to reduced CO2 emissions by your vehicle. In addition to the environmentally beneficial features of the use of EcoBright bulbs, they are manufactured and packaged with environmental responsibility in mind. EcoBright headlights are mercury free, cadmium free, and lead free and are manufactured in facilities dedicated to limiting contaminants. This means cleaner water and air, now and forever. Finally, Sylvania packages its products using paperboard packaging containing up to 100% post-consumer recycled fiber (depending on type), and 40% less plastic per year than the previous packaging. Together this reduces the amount of raw materials needed and increases the number of products that can be shipped at a time, improving transportation efficiency and reducing fuel usage and associated air pollution.
Key Features:
Save Energy - from 9 to 21% wattage savings.
Save Money - from $2 to $19 in gas over the life of a pair.
See Better - Drive Safer - 25% brighter than an aged standard bulb.
Environmentally Responsible:

I read years ago that headlights cost about 1/2 of a mile per gallon. So, if these critters use less juice than whatever you're running now, you'll be ahead on gas with them.
Other factors would probably mask any effect of these. Rain costs mpg also, not sure how much. So you'd be hard pressed to prove any gain.
BUT, if they use less juice, well, it would follow that they would use less gas as it takes gas to make electricity in a vehicle.

Maybe it is 1/2 mpg on 60 mpg Prius, but I doubt it makes measurable difference on Superduty.
My truck even driven always with the same speed have difference up to 15% what I blame on fuel from different states, but our sedan never shows noticeable difference while driving with AC on or off.
When AC compressor takes about 1000 W of power, the DRL take about 100W so if I can't measure first, how can I notice the 2nd?
Last year I bought LED bulbs for my living room because they save energy and I measure they save a lot. Now my living room is lighted up with less than 5W.
Still calculating the bulbs price and cost of energy, I will get my money back in 75 years... if I am lucky.

yes the alternator turns at whatever rpm multiplied by what the engine is running, that is true.
But the load on the alternator is what hurts fuel mileage.
Sure less wattage headlights could save a little on gas but I highly doubt it would be noticeable unless you have 100 lights on your truck.
Just to show the load an alternator can put on a engine have a look at my alternator drive by a weed eater motor test: weed eater motor portable battery charger mock up testing VPT - YouTube
That was just a load of charging an already fairly charged battery. I went on to test with more load on the battery and the most the weed eater motor could power was charging the battery, 2 100W headlight bulbs and two 55W headlight bulbs. Adding one more 55W bulb would kill the motor from the load of the alternator.
Guys that use alternators to weld with say you need at least 5hp to drive the alternator.

I think the key is within their marketing. They say that you'll save between $2 and $19 in fuel over the life of the pair. How long do those things last? 5, 6, 7 years?
Even at 5 years, are you going to notice even the best case of a $19 savings? I'd bet the SD would more in the $2 range. Being that I spend about $2,000 a year on fuel, I'd spend $10,000 over 5 years. If I play my cards right, I can spend $50 today so I can save $2 over the course of 5 years. This would only make sense to the feds.

I just don't get it...the alternator puts out x number of DC volts. How does this put additional strain on the engine if the voltage is used or not? I understand how an AC compressor being used is a factor in gas mileage as the engine has an additional mechanical load.
I compare it to a water pump at a body of water. It will put x # of GPH whether the output is used or not...

The alternator RPM is determined by engine speed. There is a pulley ratio from the crankshaft to the alternator. The load that the alternator puts on the engine varies with the load on the alternator.
If the alternator is creating 100 amps the load it puts on the engine is quite a bit larger than if it is creating 5 amps. No matter what the amperage load the voltage is relatively steady at 13-14.5 volts. The volts don't vary, the amps do.
If these headlights draw 21% less amps than standard lights the engine will use less fuel to create the amps to that power the lights. That's a fact that can be calculated and proven. Is it enough that you could measure it in the real world? That's not so easy.
Could these save $20 over two years? That's two gallons per year. If you drive 15,000 miles per year and average 15 MPG (I made up those numbers to keep the math easy) you need to save 2 gallons out of the 1000 you use. That's 0.2% increase in fuel economy, or an increase of 0.03 MPG. I'll bet you will get this increase, but an you measure it?
Notice this doesn't increase your fuel economy, it reduces the fuel economy loss when the headlights are on. With these bulbs your loss is 0.03 MPG less.

What about this;
Remove alternator from engine and mount it on a holding fixture with a hand crank and start spinning it at a constant rpm (highly subjective and unable to maintain, but imagine it could be done consistently).
Now it's putting out some volts/amps. Does one have to crank harder if the output is being used for a large device against a smaller device?
