Detailed Description

Standard Ignition EFL171 is an automatic headlight sensor used in the vehicle lighting system to detect ambient light conditions and send the proper signal to the control circuit. For 2005-2008 Hyundai Tiburon applications, this sensor supports automatic headlight operation when the original unit is worn, damaged, or no longer responding correctly. This part cross-references Hyundai OE 951002C000 for the same application. The EFL171 is also referenced by AHS505, FC761, and MSSA31 interchange numbers.

Common Issues It May Solve

  • Automatic headlights staying on when daylight conditions change
  • Headlights not switching on automatically at dusk or in low light
  • Intermittent lighting response from a failing light sensor
  • Faults caused by damaged connector terminals or sensor housing
  • Loss of automatic headlight function on a Hyundai Tiburon

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle fitment before installation. Match the square plug-in connector and 6-blade terminal layout to the original sensor on the vehicle. Confirm the application is 2005-2008 Hyundai Tiburon before replacing the part. After installation, test automatic headlight operation in changing light conditions to confirm proper sensor response.

Quality Assurance

Standard Ignition supplies electrical replacement parts for vehicle repair applications, and EFL171 is built to match the listed connector and terminal configuration for the specified Hyundai Tiburon fitment.
