Do these require any wiring modifications or adapter harnesses?

Installation method and electrical compatibility are not specified — verify fitment with your specific vehicle's electrical system before purchase. Contact support if you need clarification on your model year variant.

Can I use these as a direct replacement without removing the factory headlights?

These are designed as a direct bolt-on replacement, so no modifications to the headlight housing are needed. Standard mounting points apply.

Do the LED light bars stay on all the time or only when the headlights are on?

LED light bar operation mode is not specified in the product details. Once installed, test both daytime running light and headlight functions to confirm behavior on your vehicle.
