Peterbilt 388/389 driver-side headlight

This new headlight assembly fits 2008 and newer Peterbilt 388 and 389 trucks on the driver side. It combines low-beam, position and turn-signal functions in a single blackout housing. The unit carries DOT/SAE approval and delivers 1600 lumens on low beam at 12 V DC. It is sold individually so buyers must confirm the correct side before ordering.

Plug-in installation with existing harness

The housing connects directly to the factory wiring harness without adapters or splicing. Its dimensions of 19.7 x 10.7 x 9.7 inch and weight of 8.2 lbs match the original mounting points. Installers should verify that the truck is a 388 or 389 model from 2008 onward; earlier or different models will not align with the factory brackets.

1600-lumen low beam at 1.25 amps

Low-beam output is rated at 1600 lumens while drawing 1.25 amps from a 12 V system. The dual-colour LED position bar shifts from white to amber when the turn signal is activated. The assembly is not compatible with passenger-side mounting or with any truck series outside the Peterbilt 388/389 range from 2008 onward.

Questions about this item

How do I confirm the low-beam output is correct after installing the 31146 headlight?

The low beam should deliver 1600 lumens at 1.25 amps on a 12V DC system; verify with a multimeter at the connector and compare the beam pattern against the DOT/SAE approval markings on the lens.

What comes in the box with the 31146 driver-side headlight and what must I source separately?

The box contains the complete modular headlight assembly with integrated LED position light bar and LED turn signal; no bulbs, harnesses or mounting hardware are required because it plugs into the existing Peterbilt wiring.

Which version of the 31146 should I choose for a 2008 Peterbilt 389?

Select the driver-side unit listed for 2008+ Peterbilt 388/389; the passenger-side counterpart is a separate SKU and the 31146 is sold individually per side.
