Setup and Installation
Installing the EFL16 Flasher typically involves replacing an existing faulty unit. Always ensure your vehicle's battery is disconnected before beginning any electrical work to prevent injury or damage.
General Installation Steps:
- Locate the Existing Flasher: The flasher unit is usually located in the fuse box, under the dashboard, or near the steering column. Consult your vehicle's service manual for the exact location.
- Disconnect Power: Disconnect the negative terminal of your vehicle's battery to ensure safety.
- Remove the Old Flasher: Carefully pull out the old flasher unit from its socket. It may be held in place by clips or simply friction.
- Inspect the Socket: Check the socket for any signs of corrosion or damage. Clean if necessary.
- Install the New Flasher: Align the terminals of the new EFL16 Flasher with the corresponding slots in the socket. Push firmly until it is securely seated.
- Reconnect Power: Reconnect the negative terminal of your vehicle's battery.
- Test Functionality: Turn on your vehicle and test the turn signals (left and right) and hazard warning lights to ensure they are functioning correctly.

Operating the Flasher
Once installed, the EFL16 Flasher operates automatically in conjunction with your vehicle's turn signal and hazard light switches. When activated, the flasher unit completes and breaks the electrical circuit to the lights, causing them to blink at a consistent rate. A subtle clicking sound may be audible from the unit during operation, which is normal.
Maintenance
The Standard Motor Products EFL16 Flasher is a sealed, maintenance-free component. No routine maintenance or lubrication is required. If the unit fails, it should be replaced with a new one. Avoid attempting to open or repair the flasher, as this can damage the internal components and void any potential warranty.
Troubleshooting
If you experience issues with your turn signals or hazard lights after installing or while using the EFL16 Flasher, consider the following:
- No Blinking or Constant On: This often indicates a faulty flasher unit or a problem with the wiring to the flasher. Ensure the flasher is securely seated in its socket.
- Rapid Blinking (Hyper-flashing): This typically occurs when one or more turn signal bulbs are out or have incorrect wattage. Check all turn signal bulbs.
- Intermittent Blinking: Could be a loose connection at the flasher socket or a failing flasher unit.
- No Lights Activating: Check the fuse associated with the turn signals/hazard lights in your vehicle's fuse box.
If troubleshooting steps do not resolve the issue, it is recommended to consult a qualified automotive technician or refer to your vehicle's specific repair manual.
