Will these plug directly into my factory electrical connectors?

These are designed as direct bolt-on assemblies that use OEM mounting points. Verify connector compatibility with your specific model year before purchase — some years may require a simple adapter harness.

Do I need to aim or adjust these after installation?

Projector headlights typically include adjustable mounting brackets. After install, you should perform a headlight aim check at a shop or using a level surface to ensure proper beam pattern and compliance with road laws.

What if the LED DRL stops working on one side?

LED modules are sealed units — individual LEDs cannot be replaced. If a DRL fails, the entire headlight assembly will need replacement. This is why a quality check before installation matters.
