When you enable VehConfig 3 high intensity discharge lights it's disables the pulse width modulation that ram uses to extend the life of the halogen bulbs. That feature is what causes issue when upgrading to led or hid's in the low's. Highs doesn't use that so it's not necessary to change anything. Setting anything to led with alphaobd, to my best knowledge doesn't eliminate the bulb out warning. It is just telling the bcm there will be less voltage at those locations. I haven't had a bulb go out or have seen anyone report that by changing anything they haven't had a bulb go and lose that feature. Unlike adding canbus adapters or resistors that will not trip the bulb out warning when a bulb goes out. Because when adding led's or hid's because of the pwm will give you a bulb out resistors and canbus adapters are designed to trick the bcm into thinking everything is good even when it's not. The reason why a lot of these features are able to be enabled although were never a option on ram truck's is that FCA uses a lot of the same modules and computers across all their products. So jeeps have had hid's available for a while from the factory. So it's already in the programming on our trucks just not enabled. Now I'm not sure why on all the features that 09-12 truck's don't have certain options, other than it wasn't available for those year's. Basically alfaobd gives us access to previously only what a dealer could access plus options they could never without going to FCA for override approval and most likely not get.

Hmm.. lol. I had to Google that pulse width modulation stuff that you spoke about, never heard that before....lol. Never even in my wildest dreams have a ever thought of anything close to that.… LOL.
Although I’ve never had any issues as far as I know once I upgraded my low beams in my projectors to HIDs, if I was to get this alpha OBD thing and actually change my low beam setting to HID, will that make my lowbeams work any better, or is this a setting that I can pretty much pay no regards to since I’ve never had any issues with my new lights?
But so in other words about changing the setting for the highbeams and the fog lights, the only real necessity to change that would be so that wouldn’t have to run those little black box resistor things or or whatever they’re called that’s in line of the wiring that goes to my LED lights in my fog lights and then my highbeams, correct?
But that’s great if changing the setting for the license plate lights, the reverse lights or whatever else you may have that you changed from incandescent to LED, but it doesn’t cancel the bulb out message at the same time because LED lights can still go bad on ya… LOL. They don’t last forever.
