DRL power consumption varies widely depending on the implementation. Current production DRL systems consume from 8
watts (dedicated
LED
system) to over 200W (headlamps and all parking, tail, and marker
lights on). International regulators, primarily in Europe, are working
to balance the potential safety benefit offered by DRL with the
increased fuel consumption due to their use. Because the power to run
the DRLs must be produced by the engine, which in turn requires burning
additional fuel, high-power DRL systems increase CO<sub>2</sub> emissions sufficiently to affect a country's compliance with the
Kyoto protocol on
greenhouse gas emissions.<sup id="cite_ref-7" ="reference">

and headlamp-based systems are not allowed when DRLs become mandatory
in Europe at the beginning of 2011</font>. LEDs and low-power, high-efficacy,
long-life light bulbs produce appropriate amounts of light for an
effective DRL without significantly increasing fuel consumption or
emissions. Fuel consumption reductions of up to 0.5mpg may be found
when comparing a 55W DRL system to a 200W DRL system.<sup id="cite_ref-9" ="reference">

In 2006, the UK's Department of Transport also found significant
reductions in emissions and fuel consumption when comparing a 42W DRL
system to a 160W full headlight DRL systems.<sup id="cite_ref-10" ="reference">

DRL fuel consumption can be reduced to insignificant levels by the use
of 8 to 20W DRL systems based on LEDs or high-efficacy filament bulbs.
