These MSD Rich/Lean Indicators help determine rich or lean conditions in your engine by reading the oxygen level in the exhaust via a heated sensor. If the oxygen level is high, a red light comes on to indicate a lean condition; a green light indicates low oxygen and a rich condition. When both lights come on, you've hit pay dirt. They can be used to check fuel mixture at idle and wide-open throttle, and to fine-tune for performance or economy.
