Do these come with wiring harnesses or do I need to splice into existing lines?

These are marker light assemblies — confirm your vehicle's wiring setup before installation. You may need to test-fit first to determine if a direct plug connection is available or if splicing is required.

Are the lenses glued to the housing or can they be separated for painting?

Assembly method is not specified. If you plan to paint the housings, test-fit and disassemble carefully — some lenses are adhesive-bonded and may not separate cleanly.

What's your return window if these don't fit or the fitment is off?

Check the return policy in your cart — most parts are returnable within a set window if unopened. Test-fit before cutting any existing harnesses or fasteners to make sure alignment is correct.
