Daytime running lights on at night?

Makers never think things through.

DRLs only at the front were always going to lead drivers to drive at inappropriate times with no rear lights.

But it's not the manufacturers choice, it's legislation to have frt DRLs, if your company were making a million or more vehicles a year and you didn't have to spend the extra few dollars a vehicle to implement rear DRLs as well, you wouldn't.........they don't either.

I doubt there would be a discernible cost.

You have no idea ......when I worked in R&E even a few centimetres of wire from a loom costing a couple of cents was a significant saving.

I suspect this would be more about coding than wiring...the lights and wires are already there.

The reference to wiring was just an example of how little is significant to the manufacturers, if they had to change rear LEDs for a different type (to enable bright DRLs rear) that would be plenty significant enough. No doubt the might be other small changes which would add up also.

You are right, it is only about version coding. No HW changes at all, assuming the "rear DRLs" are more or less the same as rear parking lights (give or take different intensity).

Even the version coding option does not come exactly for free but it actually is already there, at least on most cars. Nordic countries are used to having rear lights on throughout the day and EU has allowed cars to be coded for rear lights along with front DRLs and many cars get coded differently at the shop if the customer prefers so. I'm not sure if this allowance is temporary or "permanent".

Thanks...I apparently had no idea.

The "you have no idea" comment was referring to the efforts manufacturers will go to to avoid spending more money, whether it be a few cents or a few dollars, but I had no doubt it would be taken wrongly here despite the smiley added.

In actual fact Volvo had rear running lights on because it was easier to leave them "as is" back then than to change the lighting process. And of course in the home market the lighting conditions for a lot of the year are a darn sight darker even during midday.

And as Diesel Benz almost points out rear running lamps would need to have different intensity LED or bulbs thus incurring an on cost over standard, of course to actually have them operate would mean "just" a coding change.

But if you want them on just negate the few idiots that leave DRLs on when it gets dark then a coding change would most likely work with minimum on cost, and you may be able to find a STAR operated who could fix this for you.

That's all it would be needed for.
