MAIMEIMI 2" 52mm Digital Tachometer Blue LED — Black Housing, 4/6/8-Cylinder, 12V with Adjustable RPM Warning

This slim black 52mm tachometer combines a clear blue LED readout with a tinted lens and self-calibrating startup routine to deliver reliable RPM information for cars, motorcycles, boats and light trucks. Its small footprint and included mounting hardware make it straightforward to install on most dashboards or custom pods. The gauge operates from a broad 10–15V DC range and warns when engine speed passes a configurable threshold, helping drivers monitor performance at a glance.

How does the MAIMEIMI tachometer display and warn me about high RPM?

The gauge uses a bright blue digital LED readout behind a tinted lens to present engine RPM clearly both day and night. A built-in warning triggers when RPM goes past the preset limit, giving a clear visual alert so you can respond promptly.

• Blue LED digits for high contrast visibility
• Tinted lens reduces glare under sunlight
• Configurable warning that activates above 5000 RPM
• Rapid self-calibration ensures accurate readings on startup
