Does this use the factory wiring harness, or do I need an adapter?

This mounts at the factory location and integrates with existing electrical connections. Verify connector compatibility with your vehicle before installation — adapter may be needed depending on your specific model year.

Will the LED brightness be compatible with my truck's electrical system?

LED third brake lights draw significantly less power than incandescent bulbs. Your factory wiring handles it, but some vehicles trigger a bulb-out warning light. If that happens, a load resistor or CAN-bus module resolves it — both are widely available and simple to wire.

What's the warranty on the LED bulbs if one fails?

Warranty details are handled separately — reach out to customer service with your order number and they'll walk you through coverage and replacement options.
