From a old post
In "2nd time around" issue 25 the writer described the process of replacing stock headlamps with quad "sport" types.
1. After cutting the body, you also have to cut the plastic headlamp carrier. This may be true on some early 98's also.
2. You will need to buy two new retainers p/n 55077046 and two new vents p/n 04805147
3. It is not necessary to buy a Brite Box. The existing wiring plugs straight into the quad inner bulbs (9004). To drive the quad outer bulbs (9007) use a type AR143 relay from NAPA and energized the coil from the existing high beam wire. The relay switches a fused hot wire that runs from aux battery positive to both quad outer high beams, via two new NAPA headlight connectors. This setup duplicates a factory Sport headlamp system. Note that the outer low beams are not usable, due to Dodge's choice of bulb orientation.
