What You're Getting
This is the left-hand (driver's side) full LED headlight assembly for the Volvo VNL, covering the 2018 through 2023 build. Volvo redesigned the front end lighting a few times in that run, so 'VNL headlight' isn't one part number anymore - it's a family of them depending on trim and build date.
20706633 covers the LED setup with the daytime running light integrated, same as what came stock on most VNL 300/400/670/760/860 trucks in that window. It plugs into the factory harness - no relay boxes or aftermarket wiring kits needed.
Why All These Numbers Cross
You'll see 78619545, 78619544, 78619542, and 84751279 floating around parts catalogs for this same light. Volvo revised the part number a few times as they updated internal components (usually LED driver boards or minor bracket changes) without changing the housing or mounting pattern. Functionally they're the same physical light and bolt in the same.
373-1134RXAS2 and F01097-L are how the aftermarket manufacturers tag their own version of this same fitment - different label, same application. The thing to actually check isn't the number stamped on a box, it's your VIN and the number on the light currently bolted to your truck. Bracket mounting points and connector plugs have to line up or you're stuck drilling holes or splicing wires, and nobody wants that on a headlight job.
If your old light has a number not listed here, don't assume - call us with it or the VIN and we'll tell you straight if 20706633 is your part or not.
Ordering From PartStop
We're out of Tacoma and keep this one in stock because VNL headlights are a top mover - road debris and salt spray don't care what year your truck is. Local fleets can usually get same-day pickup or same-day ship if you call before early afternoon.
Ships nationwide too, boxed heavy so it doesn't rattle around getting to you. Comes with our standard 6+ month warranty. If it's wrong for your application we'll sort an exchange - just don't wire it in permanently before you've confirmed fitment.

Frequently asked questions
Does 20706633 fit my 2019 VNL 670?
Likely yes, that's smack in the middle of the years this housing was used, but confirm with your VIN or match it against the number on your current headlight before ordering. Volvo ran overlapping part numbers during running changes, so VIN confirmation saves you a return shipment.
Is this the same as the F01097-L?
Same application and mounting - F01097-L is just how one aftermarket manufacturer labels their version of this exact headlight. Functionally it's built to the same fitment as 20706633, but always check your old part's number against ours first.
Why are there so many different Volvo numbers for one headlight?
Volvo updates internal LED driver components and makes small running changes without changing the housing shape, so they issue a new part number even though the physical light and mounting are unchanged. That's why 78619545, 78619544, and 84751279 all cross to this same assembly.
