I have a 2003 Dodge 2500 with 5.9 cummins. It has the "Lamp out" indicator light flashing on the dash. I can not find any burned out bulbs and have no brake lights. I have checked the fuses and all are good. If anyone can help me with this I would appreciate it.

It's possible your light problem is tied into the light flashing. I would fix the lights 1st & go from there...
1st & easiest thing to do would be to check the fuses again and make sure #15 is definitely good.....
The way this system operates, the 3rd (high mount) brk light is hard wired to the brk switch (off the brk pedal), the cluster monitors this and when the brks are applied sends a signal for the other lights to come on.....
So if the fuse is good and your 3rd brk light doesn't work along with the other 2, I would be looking at the switch and/or circuit. If the 3rd light is working then it looks like there is a communication problem somewhere between where the cluster monitors the 3rd & a signal gets sent to the rears.....
To be totally sure on this, I would definitely put a new bulb in the 3rd to make double sure it is in fact not working when the brk pedal is pressed.....A bad bulb here could send you on a crazy goose chase....
