Will these plug into my factory harness?

These are designed as direct OE replacements, so they use factory connector types. Before installation, verify your existing headlight connectors match — some vehicles may have different plug styles depending on original equipment.

Do I need to remove the bumper to install these?

You'll need to access the headlight mounting area from behind the bumper. Some techs do it without full bumper removal by reaching through the wheel well — test-fit first to see what works for your space and comfort level.

Can these be painted or modified?

The black housings arrive ready to install as-is. If you want a different finish, that's a custom mod — prep and paint process would be your responsibility using standard automotive products.
