Will these plug directly into my truck's wiring without an adapter?

These use factory mounting points and are designed for direct connection to your existing wiring. Test-fit before final install to confirm harness compatibility with your specific truck.

Do the LED elements stay bright enough to pass safety inspection?

LED assemblies are brighter than stock incandescent units, but visibility depends on lens quality and weathering over time. Keep the smoke lenses clean to maintain brake light effectiveness.

What prep work do these need before installation?

These arrive ready to install — no painting or modification needed. If your truck's mounting area has debris or old sealant, clean it before mounting to ensure a flush fit.
