The 4-Inch Round Amber Incandescent Front Park & Turn Signal Light Kit provides a straightforward replacement solution for vehicles using the traditional 4-inch round signal-light format.

This kit combines an amber incandescent park/turn light, mounting grommet, and wiring pigtail, giving installers the primary components needed to replace an existing grommet-mounted front signal light.

The 4-inch round incandescent format remains a common replacement configuration for commercial trucks and trailers. Comparable units use an amber lens and dual-intensity operation to provide a lower-output parking-light function and brighter turn-signal function.

Front Park & Turn Functions

This light is designed to perform two important front vehicle-lighting functions:

Park Light — provides steady amber illumination when the vehicle's parking/running-light circuit is active.

Turn Signal — provides the brighter/flashing amber signal when the turn circuit is activated.

This dual-function configuration is well established in 4-inch round incandescent lamps; Peterson, for example, specifies its comparable amber lamp for front park and turn operation.

Traditional Incandescent Illumination

This model uses incandescent lighting technology, making it a useful replacement when maintaining an existing incandescent lighting system is preferred.

Incandescent construction can be particularly useful for:

  • Maintaining an original lighting configuration
  • Replacing an existing incandescent park/turn lamp
  • Matching other incandescent vehicle lights
  • Repairing older truck and trailer lighting systems

4-Inch Round Replacement Format

The 4-inch round format is widely used across truck, trailer, and commercial vehicle lighting.

Comparable lamps in this category commonly measure approximately 4-1/4 inches across the outer lamp assembly, despite being sold as a “4-inch round” light.

For replacement installations, customers should match the existing mounting opening and lamp configuration rather than relying solely on the nominal 4-inch description.

Grommet Included

A mounting grommet is included, eliminating the need to purchase the primary mounting component separately.

The grommet allows the round lamp to fit into a compatible recessed mounting opening for a clean installation.

Pigtail Included

The kit also includes the required pigtail, making this a more complete replacement package than purchasing the lamp by itself.

Comparable 4-inch incandescent park/turn kits use plug-style pigtails at the rear of the lamp, with the wiring providing the electrical connections needed for park and turn operation.
