Does the wiring harness connect to the factory switch location?

The kit includes a dedicated switch in the harness. Tap into your existing vehicle wiring per the included diagram—no splicing required if you follow the connector points provided.

Will I need to remove the front bumper to install these?

Mounting occurs at factory fog light attachment points. Bumper removal depends on your comfort level and tools available—some installers can work around it, others prefer full access.

Can I swap the H11 bulbs for LED or HID later?

The H11 socket is standard. Aftermarket bulbs in that fitment will work, but verify compatibility with your switch's electrical load before upgrading—some LED units pull less power and may cause flickering or hyper-flash.
