On my truck, DRL puts the two high-beams in series so that they only see 6 volts each. Most headlight bulbs are in the 45-55 watt ballpark, right? So mine probably pulled 25 watts total in DRL mode.
Not much, but something. Don't think you'd ever notice 25 watts on tank by tank mileage. However, 2 amps saved on the charging system is significant if you go battery supported.
