No, this MCS flasher is designed exclusively for incandescent bulbs and will not function with LED turn signals. LED conversions require a dedicated LED-compatible flasher module with different electrical characteristics. Attempting to use this flasher with LEDs will result in non-functional turn signals.
The bulb failure indicator monitors the circuit and alerts you when one of your turn signal bulbs has burned out. This is a safety feature that helps you maintain proper vehicle lighting and comply with road regulations. When a bulb fails, the indicator will show you that maintenance is needed.
Yes, this MCS flasher is compatible with Harley-Davidson models from 1965 to 1990, which includes your 1972 model. The 2-pin design and 12-volt specification match classic Harley electrical systems from this era. However, always verify your specific model's electrical configuration before installation.
The MCS flasher is rated for 21-23 watts of power consumption. This specification ensures compatibility with standard incandescent turn signal bulbs. The actual power draw depends on the number and wattage of your connected turn signal bulbs.
While this flasher is specifically listed for 1965-1990 Harley-Davidson models, the 2-pin 12-volt universal design may work on other classic motorcycles with compatible electrical systems. However, we recommend verifying compatibility with your specific motorcycle model and consulting the wiring diagram before installation to ensure proper operation.
Installation typically involves locating your motorcycle's flasher relay unit (usually under the seat or behind the fairing) and replacing it with the MCS unit. The 2-pin connector should match your existing setup. Follow your motorcycle's wiring diagram and consider consulting a professional mechanic if you're unsure about electrical work. Always disconnect your battery before working on electrical components.
The main difference lies in the connector configuration. A 2-pin flasher (like this MCS unit) is typically used for simpler turn signal systems, while 3-pin flashers often include an additional circuit for hazard lights or have different ground configurations. Always check your motorcycle's original flasher pinout to ensure you purchase the correct replacement.
