Do I need to reprogram the RGB colors after installation?

RGB programming capability is built in, but color configuration and control method depend on whether these are standalone dimmable units or require an external control module. Confirm control setup with your installer before final wiring.

Will these work with my truck's original wiring harness?

These mount at factory headlight points, but LED headlights often draw different amperage than halogen originals. Your truck's electrical system may need a load-balancing relay or capacitor module to prevent bulb-out warnings. Have a technician verify compatibility with your specific year before committing to installation.

What preparation do these need before installation?

LEDs require clean, dry mounting surfaces. Wipe the headlight bucket area with a lint-free cloth and allow to air dry completely before securing the assemblies. No paint or primer prep is needed on the housings themselves — they ship ready to bolt on.
