Will these work with my stock wiring harness, or do I need to wire the LEDs separately?

Wiring configuration is not specified for this assembly. Test-fit first, then verify connector type against your vehicle's stock harness before final installation.

Do these headlights come with bulbs installed?

Bulbs are not confirmed as included. Order them separately to ensure compatibility with your preferred brightness and color temperature.

Can I use these with the stock trim ring, or do I need an aftermarket bezel?

Chrome housing changes the visual profile. Check fitment with OEM trim pieces on a test vehicle or contact support with your specific trim level before committing to the purchase.
