The Standard Motor Products DS357 is a direct-fit headlight switch designed to replace your factory unit and restore reliable exterior lighting control.

Built by Standard Motor Products, the DS357 headlight switch fits as a direct replacement for compatible vehicles and is manufactured in China.

What does the DS357 headlight switch do for my vehicle?

The DS357 restores manual control over exterior lights — headlights, parking lights, and instrument illumination — depending on your vehicle's wiring and original switch functions. It replaces a worn or failed switch so you can safely operate lights from the dash as intended.

• Direct replacement for vehicles that specify DS357
• Restores on/off and dim functions when applicable
• No extensive rewiring: designed to match factory connectors and mounting points

How do I know the DS357 will fit my car?

Fitment depends on your vehicle's original equipment part number and connector style. Check your vehicle's service manual or compare the old switch's shape and electrical plug to the DS357 before purchase.

• Compare part numbers and connector pin layout
• Verify mounting tabs and overall dimensions match dash opening
• Consult an OEM parts guide or installer for confirmation

What should I expect during installation?

Installation is similar to most dash-mounted switches: remove the trim, unplug the old switch, and install the replacement. Basic hand tools are typically all that’s needed, and no special programming is required for standard mechanical/electrical switches.

• Disconnect vehicle battery before starting
• Remove trim panel and extract original switch
• Plug in the DS357 and secure it in the dash opening

The DS357 is manufactured in China and shipped in compact retail packaging sized about 4.4 inches long, 2.0 inches wide, and 1.9 inches high. These dimensions make it easy to store or ship, and the unit is protected for transit.
