On my V70 the lights are usually on all the time regardless on the switch position, but I turned off the DRL setting a while back to see if it made any difference to the fuel economy. I use just over a tank of fuel a month and with the lights off most of the time, on the last tank full it averaged 31.6mpg. Now I've turned the DRL setting back to lights on all the time and done a couple of hundred miles of normal driving with the heated seat on and occasional air con use too and it's averaging at 34.2mpg.
I might have done a bit less town driving than before which helps but it's warmer outside too so the engine is up to temperature quicker
I realise that having the lights on all the time does use energy which comes from the fuel but it's such a small amount compared with other driving variables that it's not worth bothering about.
It will be interesting to see if you notice any difference Dave.
