Ialways thought the stock lights on the Dodge Ram trucks were marginal at best. I struggled with them for years before I hit on the right combination. I tried three or four different brands, Sylvania's silver stars, GE 9004HO, and even some API super somethings, they all did little to shed some new light. Another problem I was having was condensation building up in the lens. This would refract light as well as dull the reflectors. I got tired of the whole mess and removed the OEM headlights, mountings and corner lights, threw them in the garbage and installed some after market crystal clear headlights along with Piaa Star White 9004 lamps. I also drilled two weep holes in the bottom corner of the head lights. Since the install no more water in the head lights and I can finally see at night. I also purchased a Summit 9004 wiring harness kit (part # SUM-890030). It simply plugs in to the factory harness, by removing the power connection at the head lights and plugging it into the new harness, when plugging the new harness into the head light. You then mount two 30A relays and make one positive (+) and one negative (-) connection, none. Now the head lights get full voltage straight from the battery and the issue of the small factory wiring is replaced with #10 wire, very simple.
I love the new lights, they are great.
