Do these plug directly into my factory harness?

These are designed for direct fit at factory mounting points. Verify connector type with your OEM wiring before purchase — some adapters or splicing may be needed depending on your specific vehicle's electrical setup.

Will these work if my stock bulbs are blown?

Yes. These are empty housings — you'll need to source replacement bulbs separately. Check your owner's manual or parts supplier for the correct bulb type and wattage for your year.

What's the return window if they don't fit?

Contact ModSupply directly for current return and warranty details. Have your order number and photos ready if there's a fitment issue.
