United Pacific 31365: 4×6 LED headlight with high and low beam
United Pacific 31365 puts five LEDs and both beam functions in one 4×6 rectangular lamp. It is a 12V replacement for matching H4651/H4656 sealed-beam applications, with a reinforced aluminium reflector and construction designed to resist vibration. Each order unit contains one headlight.
Fitment and equipment checks
The manufacturer lists the truck applications below. Confirm the existing lamp number, mounting bucket, retaining hardware and connector functions. A combined-beam lamp still needs the correct truck-side wiring for each function.

Questions about United Pacific 31365
Does United Pacific 31365 have high and low beam?
Yes. Both functions are incorporated in this five-LED lamp. Each function needs the corresponding connection in the vehicle’s lighting circuit.
Can I remove the other high-beam lamps after installing it?
Keep the truck’s required headlight arrangement. A dual-function replacement lamp does not establish that the other lamps can be removed or left disconnected.
Which sealed-beam numbers does 31365 replace?
United Pacific lists H4651 and H4656. Compare the original lamp number, connector functions and mounting clearance rather than selecting only by the rectangular shape.
Will 31365 fit a Peterbilt 379?
The manufacturer lists 1987–2007 Peterbilt 379. The truck must have compatible 4×6 headlight mounting and electrical connections; inspect any previous housing or harness changes before ordering.
Is this a 24V headlight set or one 12V lamp?
It is one 12V LED headlight. Order the quantity required for your installation; do not connect it to a 24V system.
