Of course it's bulbs. This is a headlight discussion and Hella does not make replacement headlights for the '05 Ram. OP has an '05 Ram and I have an '05 Ram. I ordered my Hella capsules from Susquehanna Motorsports. Limited choices for the Dodge factory sockets. Also tried the Sylvania and Philips stuff from the local parts stores. Nothing helps much in those light assemblies because they are junk. Probably did not try the Hella 2.0 because those seem to be new and I have had my HIDs for about three years. The new Dodge trucks have better headlights.
yeah the 90s dodges had horrible light design. the ram sport made amens by using the 4 bulb housing that was much better. My 1998 Dakota was the same. horrible.
I have the 2.0s in my patriot and they are great. I have the truck lites in my JK and they are the best light I have seen for the 7" round crowd, and have seen EVERY respectable light offered. TLs are much better than the rest.
