This is a cruise ON/OFF indicator for vehicles with aftermarket cruise control switches. I purchased it but never installed it, and have been storing it. It is unused, so I have not confirmed its operation. No claims, no returns, and no cancellations are accepted. Please refrain from purchasing if you are sensitive to used items. The red LED lights up in standby mode, and the blue LED lights up during cruise control. The LEDs dim in conjunction with the headlights. The light intensity can be adjusted in 6 steps (4 steps when dimmed). Sound is available for each ON/OFF/SET/RES/CANCEL button! (Sound OFF function available) There are 5 wires. Includes electrical tap connectors.
