If I use Forscan to run the DRL's as low beams and parking lights will it also light the taillights or just the front parking lights? I am asking because I installed a set of the raptor grill lights that I am thinking about running with my DRL's and would need to do this change in Forscan for that to happen.

DRLs are front lights only.

My understanding is that low beams + parking lights as DRLs is not possible. It's something that I've wanted to do as well, since it's essentially the same as the headlights in the "on" position.

You can have low beams as DRL or parking lights as DRL, but not both. Parking lights as DRL will light up both the front and rear parking lights.

edit: ignore this. looks like you can do low beams and parking lights

Per the Forscan excel sheet

When did DRLs become commonplace in US?

Not true. I have parking lights set on my DRLs and its 360, not just front.

Those are not DRLs despite what FORScan allows you to do.A daytime running lamp (DRL, also daytime running light) is an automotive lighting and bicycle lighting device on the front of a roadgoing motor vehicle or bicycle,[1] automatically switched on when the vehicle's handbrake has been pulled down or engaged in-gear, emitting white, yellow, or amber light. Their intended use is not to help the driver see the road but to help other road users identify an active vehicle.[2]

Ok, thanks for the Webster's Dictionary response. However, that's not what the OP was asking and you know it.

Ok follow up question, do the taillights come on with only the low beams set as DRL's, (factory DRL setting) I haven't ever looked or noticed.
