Do these mount to factory locations, or do I need custom brackets?

These are designed for OEM mounting points. Verify fitment against your specific chassis before purchase — some variations may require minor reinforcement or adapter work.

Will I need a wiring harness adapter to plug these in?

Mounting method and electrical connections are not specified in the product data. Test-fit and compare the connector type to your existing wiring before committing to install.

Are the bulbs included, or do I need to transfer them from my old lights?

Bulbs are not confirmed as included. Plan to reuse your existing bulbs or source replacements separately.
