Why wouldn't the DRLs pass in Canada?
Well because from what I’ve seen with my own two eyes- and I see them a lot because I drive for a living, the white lights in these headlights on these trucks just doesn't seem to change intensity whether it’s day or night so being that because they are on all the time, I figured they wouldn’t pass as legal DRL’s in Canada because if they don’t get brighter during the DAY or dimmer at NIGHT, they wouldn’t be on all time because if they’re supposed to be a certain brightness to pass as true DRL’s, they’d have to either shut off when the headlights are on or dim to a lower brightness.
And yes, the lamps still light up amber when the turn signal is activated and turns back to white when deactivated. There are a few different LED headlight models available depending on the trim which have slightly different ways in how the turns and DRLs operate.
Well yeah, I would imagine that whether they are true DRL’s or not, if they’re that close to the turn signals then it would only make sense to make the one side dropout when that same side turn signal is on just to make them more visible.
I've seen a large mix of these Rams (both 1500 and 2500/3500) on the road during the DAY with the DRLs shining at maximum brightness and others at a dimmed level and even some with no DRL on at all. Don't know if the dealers are supposed to be setting the DRL function when they get them from the factory or what. Or maybe some of these owners were screwing around with AlfaOBD and changed the settings. Whatever it is, I just don't see any uniformity on the streets.
If they’re American trucks, I highly doubt the dealer is supposed to do anything like that unless the customer wants them activated because they’re not required here and I would assume the trucks that roll off the factory line that are destined for Canada, they’d probably already have their DRL’s activated to Canadian specs.
But unless the BCM’s are different in those trucks, the only thing Alfa OBD can do is activate them, deactivate them, enable or disable the DRL dropout and give you the option to set whatever you want as your DRL’s and in my 4th Gen, it’s highbeams, lowbeams, fog lights, front turn signals, whatever the SRT lightbar is and if you cut the dedicated DRL wire to each headlight plug, you can hook whatever aftermarket lights you want to those and unless there’s a setting I don’t know about, you can’t disable the DRL dropout when the headlights are switched on.
I have heard of people cutting the wires to those white lights in the 5th gen Rams because unlike my 4th gen, as soon as the key is switched on, those white lights turn on and supposedly a lot of people don’t like that. In my truck when the DRL’s are activated, they don’t turn on until the engine is running and the transmission is shifted into reverse or drive.
