Hi, again, everyone. Well, it looks as if I am not going to be using LEDs in our Dak. I received the 3157 bulbs, and ran into the oddest problem I have ever heard of. When the LED bulbs were plugged into the sockets, nothing was turned on, there should have been no current flowing anywahere. Right? The led bulbs lit up, at low intensity, and when I turned the parking lights on, there was no change. I had Krystal step on the brake pedal and then turn on the hazard flashers, and there was still no change. I am waiting now for a return authorization number so I can get a refund. Thank you all, anyway.

Shouldn't be that expensive, I think the maglite bulb was $15 or so, maybe less.
Also for the 3w bulb I was thinking of these:

Well there's a difference between the 3w LEDs for your truck and the ones they make for the maglites. The ones for the truck have 3 individual 1w bulbs on them, and are manufactured differently. The ones in the maglite, would make a pair of bulbs for our trucks about $60/pair. They're two different types of LEDs. And yes I do have the high power ones on my truck.

RE: LED Bulbs
no, LEDs need resistors to work on 12v systems to begin with, and yes the bulbs have those. However, you need load resistors that will equal out the current so that it tricks the on board computer into thinking there's a normal bulb in there. The LEDs still light up instantly, and look just as nice, it's just something needed to make them work on the system.
this is what you need, what you would do is you would splice one end into the turn signal circuit wire and the other into the ground wire. It won't short it, just acts as an additional place to draw current.

RE: LED Bulbs
I chose to go with SBL because, as you will see if you check the website, it says drop-in replacement with internal resistors. Maybe my command of the English language is not waht it should be, but 'drop-in,' and 'internal resistors' seemed to indicate that I did not have to go the external resistor route. Additionally, the owner's manual indicates the proper bulb for the Dak is the 3057LL. Trouble is, everyone seems to be under the impression that the 3057LL does not exist. It seems rather strange to me that Dodge would require a non-existent bulb.

RE: LED Bulbs
The internal resistors are to allow them to work with 12v power. They technically are ready to work but the problem is the truck's computer isn't seeing what it expects to because LED's use less current and have less resistance. This is what the load resistors are for, they combined with the LED's makes it so the computer sees the resistance it expects.

Turn signal issues with LED bulbs
LED brake/tail lamps will not flash with thermal flasher units due to their extremely low current draw. Also, with stock flasher units, the turn signals may flash faster than normal (Hyper-Flash).
These installations will require an electronic flasher unit, available in our car bulb shopping category (for some vehicles) or at your auto parts store. Try to find flashers designed to work with LED bulbs, they will say "LED compatible". Often HEAVY DUTY flashers will also work with LED bulbs.
We offer some LED Flashers in our Tail/Brake Turn Signal Bulb category but we do not know which one (if any) will fit your vehicle. You will have to compare the pin-out of your flasher with the pin-outs of the flashers we offer, to see if we have a match, BEFORE you order one. Sorry but we do not have a flasher application list or the expertise to tell you which of our flashers will fit your vehicle.
Another fix is the installation of Load Resistors which are wired across (in parallel with) the turn signal bulbs to simulate the load of a standard filament bulb. We also have these available in our car bulb shopping category.
