Does anyone know how much fuel is used when running

FYI, DRLs usually run at 70% of full low beam strength. Makes bulbs last far longer.
Don't know additional drain, but you might be able to work backward from energy used, and alternator load.

Here it is... "virtually NO INCREASE in fuel consumption..."
Found this on the initial review on car.kak.net
"Daytime driving lights for extra safety
The significant improvement of safety provided by permanent operation of the headlights also during the day used to mean extra energy and fuel consumption amounting to approximately 0.2 litres per 100 km. This is why, with the exception of a few countries, this technology has so far not been introduced Europe-wide. And this is a shame, considering that daytime operation of the headlights helps to enhance driving safety, particularly when the sun is at a low angle, when driving on the motorway or in town.
With the low and high beams in the xenon plus headlights being integrated in one and the same - the outer - unit, the inner reflector remains free for daytime operation of the headlights. A dimmed lamp serves as the source of light, while the other lights are switched off. The result is virtually no increase in fuel consumption whatsoever."<ul><li><a href="http://car.kak.net/modules.php?op=modload&name=News&file=arti cle&sid=3523">About half way down the page</a></li></ul>

Life Rules, thanks for hunting down the info
So that means for every 500 KM's (300 miles) you use 1 liter (roughly 1 qt). In monetary terms at today's prices 40 cents/300 miles.

Those sound like "city lights." Common items in Europe.
I changed out to Euro lights housings on my Alfa for a better beam pattern, and it has a seperate low powered bulb that comes on with the parking lamps. Very useful at dusk. The fog lights are controlled separately.
