Do these headlights come with bulbs?

The LED light bar portion is integrated into the assembly. If your truck still uses separate bulb housings within the headlight, bring your OEM bulbs forward to the new assembly—they'll fit in their designated slots.

Will I need to reprogram or add a wiring harness?

These mount at factory connection points. Basic plug-and-play operation requires no external relays or modules; they wire directly to your truck's factory headlight connector. If you want control over the light bar separately, you can run auxiliary wiring, but it's not required for headlights to function.

What prep is needed before installation?

Unbox and inspect both assemblies for shipping damage. No painting or sanding required—the assemblies ship ready to mount. Disconnect your battery before disconnecting factory headlights, then reverse the process with the new units.
