Do these lights plug directly into the factory connectors?

These mount at factory locations, but connector compatibility depends on your specific harness setup. Test fit before final installation to confirm plug type and any adapter needs.

Will these work with my factory wiring without modification?

Electrical integration isn't specified — have your harness checked before committing to installation. Some builds require a simple adapter; others integrate straight in.

Are bulbs included or do I need to supply them separately?

These are full LED assemblies with integrated LED elements — no separate bulbs to install or replace.
