4 Stroke CDIs & Light Boxes

CDIs and light boxes used in 4-stroke engines manage ignition timing, spark strength, and electrical output to lighting circuits. Many of the components in this category are designed for GY6 50cc–150cc scooters, 110–125cc ATVs, and similar small recreational vehicles. Over time, heat, vibration, and electrical wear can cause CDIs to fail or weaken, leading to misfiring, no-start conditions, or inconsistent power delivery. Light boxes may degrade as well, resulting in dimming or flickering lights. Replacing these modules is a simple and effective way to restore proper ignition performance and stable electrical output.

This category may include:

• CDI modules for GY6 and other 4-stroke small engines
• Light boxes for voltage control and lighting stability
• AC and DC style CDIs depending on the vehicle’s wiring configuration
• Plug-and-play replacement units for scooters, ATVs, and go-karts
• Components compatible with TaoTao, Roketa, Jonway, Peace Sports, and similar brands

Additional notes about this collection:

• Helps resolve spark issues, misfiring, and no-start conditions
• Supports proper lighting voltage and overall electrical reliability
• Useful during ignition troubleshooting or electrical system restoration
• Designed for accurate fitment when matched to connector type and engine platform
