Mercury – MP Alert Replacement Light (Oval) | Service Part | 8M0109506

Overview

The Mercury 8M0109506 MP Alert Light is the direct service replacement for the oval-style smart lights used in the Moving Prop (MP) Alert system. If an existing light becomes damaged, dim, or fails after long-term exposure to sun and spray, this replacement restores full visibility and keeps the MP Alert system working exactly as intended. It installs quickly and plugs into your existing MP Alert harness with no modifications.

Key Features

• OEM Replacement Light – Direct swap for the oval MP Alert smart light used in Mercury MP Alert kits.

• Restores System Performance – Ensures your MP Alert setup maintains proper visibility and warning coverage.

Compatibility

• Mercury MP Alert Systems (oval light style)
• SmartCraft-compatible MP Alert installations

Performance & Practical Benefits

This replacement light keeps your Moving Prop safety system functioning properly. Once installed, the light activates automatically with the rest of the MP Alert system, flashing anytime the propeller is in motion. The bright LED output helps swimmers, riders, and anyone near the transom recognize when it’s unsafe to be close to the prop. It’s an easy way to restore full warning capability without replacing the full kit.

Why Buy OEM

Mercury’s MP Alert system depends on precise LED brightness, water sealing, and communication with the control module. OEM smart lights are built to match the system’s timing and performance. Aftermarket lights often lack proper sealing or electrical behavior, which can compromise the warning system. The OEM replacement ensures the system stays consistent and reliable.
