Brake systems help trucks slow down. JakeLight helps other drivers understand that it’s happening. Rather than relying on pedal pressure, JakeLight uses real-time vehicle data to activate brake lights only when deceleration is genuine.
Core Innovation
Smart Detection
Monitors engine retarder, transmission retarder, and deceleration using J1939 CAN data.
Accurate Activation
Brake lights trigger only when deceleration exceeds calibrated thresholds and a retarder is active.
Simple Integration
Designed for plug-and-play installation—ideal for both OEM manufacturing and retrofit applications.
Compliance & Protection
Fully FMVSS 108 and SAE J1939 compliant with patented logic and hardware architecture.
Real-World Performance
Fleet testing confirms:
Faster reaction time from following drivers
Greater safety awareness on downgrade routes
Reduction in rear-end collisions and near-miss instances
“Since adding JakeLight to our downhill routes, our near-miss incidents have dropped noticeably. It’s peace of mind—and proof of innovation.”
— Fleet Safety Director, National Carrier Group
Why It Matters
Standard brake systems communicate pedal pressure. JakeLight communicates real deceleration, providing a more truthful and reliable safety signal.
Conclusion
JakeLight turns critical slowdown moments into clear warnings—before accidents happen.
