Hi I have my rock lights connected to dome lights with a 4 pin relay. The problem is the relay chatters/buzzes when the lights are dimming. Any solution to this or any other wiring solutions? Thanks. 12 volt battery to pin 30, ground to 85 ,car dome light to 86, and rock lights to pin 87. I have attached a drawing/diagram of my connections.

Why not try a solid state relay?

Okay thank you. how does a ssr work and how would I connect the wires like my diagram? Does it have different numbers for terminals? Do I need any diodes in my connections?

Typically, the input terminals are similar to the coil on a mechanical relay but are terminals 3 and 4. Just make sure it's a DC-DC SSR that meets your voltage and current requirements.
Check Amazon and eBay. You shouldn't need diodes and this may be the simplest solution to do what you want. A transistor could possibly work as long as it meets the power requirements, but you'd need to do some math and find proper resistors as well.
