Frequently Asked Questions About Mack CX Truck Headlights
Will these headlights fit my specific Mack CX model year?
Our Mack CX headlights are designed to fit CX612 and CX613 models from 1998 to 2007. These headlights use standard Mack mounting points and connectors for direct plug-and-play installation. If you have a Vision model or a CX with custom modifications, please contact our support team to verify compatibility before ordering.
What's the difference between halogen and LED headlight options?
Halogen headlights offer traditional lighting at a lower price point and are DOT approved for all states. LED headlights provide 3-4 times brighter illumination, last up to 50,000 hours compared to 1,000 hours for halogen, and draw less power from your electrical system. Both options come in chrome or black housings. Note that some LED models may require additional wiring harnesses depending on your truck's electrical configuration.
How difficult is the installation process?
Installation typically takes 30-45 minutes per side for most drivers with basic tools. You'll need a Phillips screwdriver, 10mm socket, and potentially a trim removal tool. The process involves removing 4-6 mounting screws, disconnecting the old wiring harness, and reversing the process with new lights. No cutting or drilling is required. Some LED conversions may need an anti-flicker harness if your truck shows warning lights after installation.
Are these headlights DOT approved and legal in all states?
All halogen headlights we carry are DOT approved and legal nationwide. LED headlights vary by manufacturer - look for DOT or SAE markings in the product description. Some high-output LED models are marketed for off-road use only. We recommend checking your state's specific regulations, as some states have restrictions on aftermarket LED conversions even with DOT approval.
What's covered under warranty and what are common failure points?
Most headlights come with a 1-year warranty covering manufacturing defects, moisture intrusion, and electrical failures. Chrome finishes typically include a 90-day warranty against peeling or discoloration. Common issues to watch for include condensation buildup (usually covered under warranty), loose mounting tabs from vibration (check and tighten every 6 months), and wiring harness corrosion in high-salt areas. LED units rarely fail but when they do, it's typically the driver module rather than the LEDs themselves.
