The fuse box you need is under the hood near the battery. It's a large black box, usually held closed with clips. There should be a fuse layout diagram on the inside of the cover panel you take off. Check fuses B, C, E, F and G. B, C, E and G are 15 Amp fuses. F is a 20 Amp fuse.
Try the web link below for the layout and listing of the fuses.

I put aftermarket tail light and headlights LED in my in my truck 06 Dodge Ram 1500 turn signals got hyper flash trying to replace the relay cannot find

Check the headlight switch. The power goes from the fuse to the headlight switch and then to the dash and running lights.

WAY TO GO !!! another "great idea" from vehicle manufactures

These fuses are located under the hood in a fuse/relay box. You may have a problem with the daytime running light module also. If the fuses aren't blown have this madule check.

Here's a link to a pdf file containing the headlight wiring diagram for your year model Dodge Ram 1500..
I can't help but notice that you say you've replaced the headlight relay? That's quite odd, because there is NO headlight relay on this vehicle- only a 40 amp fuse located in the power distribution box that sits behind the battery inside the engine bay.
The switch is notorious for burning out because there is NO RELAY on this vehicle, and there is a recall (#819) but this only affects 3500 models even though the headlight wiring is the same for 1500,2500 and 3500 model Rams.
Here are two more links that will help you troubleshoot your headlights problems.
