3RD Gen New Headlamp Assy Now Lamp Out
04 Ram 1500 SLT Quad Cab. Installed new headlamp assy on right and left. Truck cranked and headlamps or just parking lights on, no alarm or lamp out light. When you turn on the signals or hazards then the alarm comes on and the lamp out light is blinking. If you touch the brake the alarms go off and the lamp out blinking stops. No problems at all if you dont turn on the headlamps. I just cant have headlamps and signals unless I touch the brake. I have replaced both headlamp assy's, both taillight connector boards, and all external lamps to include the CHMSL. Tag lamps also. No led's. I was going to change the flasher, brake switch, and possibly the headlamp switch. I'm going to check all the new lights and make sure everything is still burning. Lets hear it guys! I dont want to start throwing parts at my truck. Any information, troubleshooting procedures would be greatly appreciated.

I would beg/borrow a scanner that will check codes that a normal cheap scanner will not. I am betting you have FCM/BCM codes that will require a more expensive scanner to see.
Start looking at Fuse box (IPM) connections that plug into the bottom of it and the FCM/BCM that is bolted to it and has a large rectangle connection.
Search Ebay or Google for pictures of Dodge Ram FCM, BCM, and IPM to see picture of them so you know what modules to look for.

Edit... Thinking a little more on this. The pins in the new headlight assembly signal socket could be configured in wrong position. Try using signal socket from old light assembly. I had similar problem with TYC I installed. Hopefully you have old lights still
