Indicator Light:

The spark plug light checker assists the tester in making further adjustment plans based on the indicator light. An intense bright white light indicates a healthy spark, while jumping colors suggest weak contact current. No light indicates no current is passing. This helps you identify which cylinder is problematic and trace the exact cause.
