Keep your headlight circuit under dependable control with the Standard Ignition Headlight Switch DS-531, a replacement switch built with copper alloy conductors and 100% tested for mechanical and electrical switching performance. It is a direct-fit replacement for many vehicles, among them the 1994-2004 Ford Mustang, the 1991-2002 Ford E-150 Econoline and the 2003-2008 Ford E-150. See the Buyer's Guide tab for the full list and engine details.
The headlight switch is the driver's control for turning the headlights on and off. If a worn or failing switch is causing headlights that won't come on, flicker or work only intermittently, the DS-531 replaces it.
- Quality control from start to finish: Standard Ignition is a global manufacturer of original equipment ignition products and keeps quality control throughout manufacturing, from componentry to the finished product.
- Copper alloy conductors: Chosen for superior electrical conductivity with low resistive losses.
- 100% tested: Every switch is tested to verify both its mechanical and its electrical switching performance.
- Built for the shop: A robust design and high grade materials meet the demands of today's service professional. The switch draws on decades of research and development focused on what technicians need.
Signs that a headlight switch may need replacing include headlights that won't turn on or off, lights that flicker or cut out intermittently, and a switch that feels loose or won't click into position. Bulbs, fuses, relays and wiring can cause similar symptoms, so diagnose the circuit before replacing the switch.
