Do these come with bulbs installed?

These are lens assemblies only. Verify your current bulbs fit before ordering—most direct swaps reuse existing housings, but always test-fit first.

Will these bolt straight into the factory bumper?

These are designed for stock bumper fitment. Check that your bumper openings match OEM dimensions—if you've got an aftermarket bumper, confirm clearance before committing.

Do I need to prime or prep these before installation?

These ship ready to install as-is. If you want to paint them to match your bumper color, basic surface prep with fine grit sandpaper and primer will work—refer to your paint supplier for their specific steps.
