Why This Kit Outperforms Generic LEDs

✅ Precision Heat Management

• Copper-core PCB design reduces operating temperature by 28% vs aluminum-based competitors (verified through 1,000hr continuous testing)

• Axial fan placement optimized for Silverado's tight tail light housings

✅ Voltage Spike Protection

• 11-16V dynamic input range matches Silverado's charging system fluctuations (per GM SI 2017-08-44-001A)

• Reverse polarity protection prevents damage during trailer light hookups

✅ Optical Engineering

• Front turn signals: 72° beam angle eliminates side blind spots

• Reverse lights: 30° focused beam throws light 38ft (tested with 8ft bed + tailgate down)

✅ Proven Longevity

• 3,000hr accelerated life test showed <8% lumen decay (generic bulbs decay 35-50%)

• Vibration resistance validated on simulated Silverado frame (20Hz-200Hz sweep test)

✅ Silverado-Specific Fixes

• BCM-friendly design prevents U0184/U0199 error codes common with aftermarket LEDs

• Dual-contact brake light bases solve hyper-flash with trailer wiring

What Competitors Avoid Disclosing

🔧 Heat Management Reality
Generic LEDs show 35% lumen decay at 1,000hrs (per UL 8750 testing). Our copper-core design maintains 92% output.

⚡ BCM Compatibility Risks
Non-GM-specific bulbs cause:

• DTC codes U0184/U0199

• Battery drain during cold starts

🎯 Optical Precision Matters
Our front turn signals use collimator lenses to:

• Maintain 3.2° beam divergence (GM specification)

• Prevent glare to oncoming traffic
