Do these use factory bulb sockets or do I need new bulbs?

These housings integrate LED daytime running lights but still accept standard halogen or HID bulbs in the main beam cavity. You may need replacements depending on your current setup — verify bulb type before ordering.

Will these bolt straight into my truck or do I need to modify anything?

These mount at factory rocker points — no drilling or frame modification needed. You'll need basic hand tools and a test-fit before final fastening to confirm alignment.

Do the LED daytime running lights draw power from the main headlight circuit?

The LED DRL circuit is separate from the main beam. Exact wiring configuration isn't specified here — review the installation manual or reach out for detailed electrical diagrams before you commit to a install timeline.
