Will this work as a direct swap without cutting or splicing wires?

Yes. This lamp plugs into the factory housing connector with no modifications. Pull the old bulb cartridge, install the LED unit, and you're done.

Does the red function work automatically or do I need to wire it separately?

Both white and red channels are factory-mapped — they activate with your existing brake and reverse circuits. No extra wiring required.

Can I return this if the beam pattern doesn't match my expectations?

Returns are handled through our standard policy. If brightness or color output doesn't suit your setup, contact customer service with photos of the installed lamp.
