Daytime running lights

[1990RangerinSK]

Generally DRL are not as bright as low beams.

People like the DRL that come on with the key because they go off with the key... and thus don't damage the battery if someone forgets to turn them off.

So how does that work? A voltage reducer for the low beam filament when in drl mode? Or did the canadian trucks have a different grill with seperate lights for the DRLs?

Daytime Running Lights on Rangers in Canada use the high beam headlights at a lower voltage, or in some cases (Chrysler minivans between 1996 and 2000 for sure, maybe later ones up to 2006, as well, and some GM cars, and maybe some other Chrysler products) use the front parking lights at full intensity. On models that use the high beam headlights, when you turn the headlights on the DRLs turn off.

Since DRLs use lights that exist on both Canadian and US vehicles, they look identical. Same grill, same lights, same number of lights.

I know there are some vehicles that use a little black box that connects the headlights in series to run at half intensity.

Thanks for all the replies guys. Yes I'm in Canada and yes I found the little black box with the cooling fins behind the drivers headlight.(mounted to the inner side of the rad support)
My ranger is an off road only "mud truck" and twice now I've gone through water deep enough to get into the headlights and blow the bulbs.(the seals are gone in the light buckets)
So, if I'm ripping around during the day I don't want the lights on and hot in case cold water splashes on them. Fix the seals or replace the headlight buckets you say? But that costs money. I saw a LED light bar today on sale and I almost got it...but I didn't. Working on sealing the air box and running a snorkel now.
