Fog Light for Peterbilt 579 587 Kenworth T660

This United Pacific Industries fog light is designed as a direct replacement for Peterbilt 579, 587 and Kenworth T660 series trucks. It matches the OEM part number P54-1062-100 for precise fitment. The unit is sold individually for single-side repair or replacement. Buyers needing a complete pair should order two units.

Thermals Noise Power Draw

As a passive lighting component, the fog light generates minimal heat during normal operation and produces no audible noise. Electrical draw is limited to the factory-specification bulb circuit already present in the vehicle. No additional cooling or power modifications are required for installation.

Plug-In Harness Compatibility

The light plugs directly into the existing wiring harness without adapters or splicing. This factory-style connector reduces installation time and preserves the original electrical layout. The 6.2 x 5.7 x 5.2 inch housing weighs 0.94 lbs and aligns with stock mounting points. Fleets without these specific truck models cannot use this part.

Questions about this item

How do I install the 31234 fog light on my Peterbilt 579 and what step is often missed?

The fog light plugs directly into the existing wiring harness for an OEM fit; the step often missed is ensuring the connector seats fully and locks into place before securing the housing.

What maintenance or replacement will the 31234 fog light need over time?

The sealed assembly requires no routine maintenance; replacement is only needed if the lens cracks, the housing is damaged, or the internal lamp fails.

What is the first limit the 31234 fog light hits during sustained use?

The primary limit under sustained use is thermal — the compact 6.2 x 5.7 x 5.2 inch housing dissipates heat passively, so extended operation in high ambient temperatures can reduce lamp life.
