What You're Getting
This is a complete RH LED headlight assembly for Volvo VNL trucks built 2018 through 2023 - housing, LED low/high beam elements, DRL strip, and the connector pigtail all in one unit. Volvo redesigned the VNL headlight for this generation to an LED setup, so this doesn't cross with the older halogen VNL lights from pre-2018 trucks.
VNL trims moved some things around over the years - VNL 300, 400, 670, 760, day cab vs sleeper - but the headlight assembly itself stayed consistent across trims for this body style. Still, passenger side and driver side are NOT interchangeable, so double-check you're ordering RH before it ships.
Volvo's OEM number for this is 20796088. If the sticker on your old housing or the parts breakdown from your dealer says that number, you're in the right spot.
Why All These Numbers Point To One Part
78619544 and 78619542 show up a lot in this listing because Volvo re-numbered this assembly at least once during the production run - common with a multi-year part when a supplier or component inside changes slightly, even if the housing and mounting stay the same. 84751279 is another Volvo internal number that's crossed to the same physical part.
20359833 and 20496653 are earlier or superseded Volvo numbers that some parts counters still have listed in older systems - they point back to this same current assembly. The 373-1134RXAS2 is the aftermarket manufacturer's own part number for their version of this light, built to bolt into the same location and match the OEM harness.
None of this matters more than what's stamped on your actual truck. Pull the old headlight, find the number on the back of the housing or on the harness connector, and match it against this list. If it's not exact, give us that number anyway - we can usually tell you if it's a match or a different generation.
Ordering From PartStop
We're in Tacoma and keep VNL lighting in stock because it's one of the most common line items fleets call about - cracked lenses from rock chips, water intrusion killing the LED board, that kind of thing. If you're local, same-day pickup is usually doable if we've got it on the shelf.
Ship nationwide too, and this one's not an oversized freight item so standard ground shipping covers it in most cases.
Comes with our 6+ month warranty. Before you order, confirm fit against your VIN or the number off the old headlight - this is a direct replacement for the applications listed, but Volvo's changed suppliers and running changes enough over the years that we'd rather you check first than deal with a return.
20796088 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 20796088. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 20796088 fit my 2019 VNL 670?
Should - that's the Volvo OEM number for the RH LED headlight across the 2018-2023 VNL lineup regardless of trim. But confirm by checking the number on your current headlight housing or running your VIN, since running changes happened during this production run.
Is this the same as the 373-1134RXAS2 unit?
373-1134RXAS2 is the aftermarket manufacturer's part number for essentially the same physical assembly - same mounting points, same harness connection, cross-references to the OEM 20796088. It's not a Volvo-branded part, but it's built to the same fitment.
My old headlight has 78619542 stamped on it, not 78619544 - is this still right?
Likely yes - those two numbers are both Volvo internal part numbers tied to the same 20796088 assembly, just from different points in production. Give us a call with that number before ordering and we'll verify it against current cross-reference data.
