I have a 2011 Ram 1500. Recently I used alfaodb to have DRL on for my front blinkers. However, the DRLs are orange during the day. I want white drl during the day and only orange turn signals. If I turn on the parking lights or use automatic night switch at night, the DRLs are white and blink orange. I have tried several led bulbs, all do the same. My latest attempt was using LASFIT 3157 LED Bulb Switchback and it too is orange drl. The only thing bad about lasfit is blinking white to orange with the headlights on but I will see if drl drop out will fix that. During the day, the switchbacks are of course orange all the time and blink off back to orange. Now my question is has anyone fixed switch back drls to white vs orange. I have read that the polarity might be backwards for drls but couldn't find a solution.

Can you set drl to parking lights in Alfaobd?

The turn signal sockets have 3 wires going to them, a ground, a parking light, and a turn signal wire. With a switchback bulb, when power is supplied to the parking light wire they will illuminate white, when supplied to the turn signal wire, they illuminate orange. Since you have the truck sending power to the turn signal wire for the drl, of course it’s illuminating orange, no different bulb will change that.

Alfaodb indeed says Turn Signals for Reconfigurable Parameters: DRL Lamp Location meaning that would burn out a regular 3157 meant for intermittent use. No wonder this location with regular bulbs or leds with resistors gets so hot. Maybe I'll see if alfaodb can update that to front parking lights.

This is how they function in the Rams. The amber is the higher wattage side of the bulb. So, during the day, the drl runs off the turn signal, hence the amber. At night, the drl runs off the lower wattage side, the white side, aka parking light. As you use the turn signal, the white should drop out and should blink amber on/off. There is no function in Alfaobd to set the drl to the parking light, which would solve this issue 100%. Doesn't matter what bulb you use, they'll all do the same thing. It's just a matter of the signal the BCM sends to the bulb.
