A set of PNP wiring adapters for DRL (RS) cars. These will make the DRL foglights when your parking lights/headlights are on and the Halos come on when the DRL are on. The connectors require no cutting, splicing, soldering, etc.
These are from AAC and are $9 when you buy the P13 bulbs. I bought the Adaptive harness and do not need these.
