By daytime running lights, I presume you mean the sidelights, but those can be turned on at any time and your car already has them, so I'm not sure if I know what you mean.
Just for clarification, (because I'm better with pictures, due to misinterpretations at times) do you mean front fog lights such as these?
Or do you mean, some sort of additional daytime running lights, or slim lights, such as these?
If so, then how would you prefer for them to switch? If you want a separate, manual toggle switch with a relay, then that's pretty simple. I'm sure we could accomodate you. Or perhaps you would prefer for them to stay on permanently? That should be even simpler. Daytime running lights in many countries are permanently on, regardless of how the driver controls any other lights on the car.
I understand however that it's becoming ever more popular for people to fit these slim aesthetic L.E.D., front light sets. I'm not sure if they're actually designed to have the effect of daytime running lights, but they usually are fitted for aesthetics, over functionality.
As I said, really, daytime running lights are simply your side lights, wired to be permanently on, or a front and rear set of additional, typically bumper mounted lights, which are typically only as bright as the side lights, and which only serve to warn other road users of your presence.
On a bit of a rant..Apparently, some Taiwan drivers seem to think that their fog lights serve as some sort of all weather, all hours running lights. This always drives me crazy, as I can't count the number of times I'm dazzled in perfect weather, and then the daft driver doesn't even react when I flash them. Flashing your lights in someone's rear view mirror usually does the trick back home, as the driver wonders what you are flashing, quickly does a lights check, then realizes they actually left their fog on, and quickly switch it back to off.
It seems to me that many Taiwan drivers actually mean to leave their fog on.
My work partner is also frustrated by this habit, and he's Taiwanese. He has come up with the potential plan of fitting a very high luminescent lamp to a desecrate location on the rear of his car, so that he can overtake a chap who won't turn off his fog lamps, and then dazzle the bejezus out of him.
I don't actually advise anyone to do this, as it really only serves as oneupmanship, and is quite childish, and really quite dangerous. I can however see the immensely frustrating reason for wanting to however.
