Left headlight assembly for a 2019 Honda Civic
Year, model, and side give the estimator a real housing to work around. Headlight by itself averages a compact lamp against a full LED unit.
A modern headlight assembly packs to around 26 × 18 × 14 inches at 6–12 lb. It is light but bulky and brittle — dimensional weight sets the price and the mounting tabs set the risk. The lane and the class of service finish the calculation, so quote the box after it is packed.
A 24 × 12 × 12 in carton at 7.7 lb came back at $25.83 on FedEx Smart Post over the lane below.

Two working ZIPs, quoted live. Missouri across to Virginia is several zones, and a shorter hop would lower every line in the table.
Volume wins by a mile: 24 × 12 × 12 ÷ 139 reaches about 24.9 lb where the scale reads 7.7 lb, so the carton is what is being priced. That is the trade a headlight always forces, since the padding is what keeps it whole.

Every figure is the complete checkout price, label and SMKlog's portion in one number, with nothing to follow. FedEx Smart Post was lowest on the day at $25.83. Rate tables move and lanes behave differently, so use this as one assembly on one date and quote your own ZIPs at packing time.
About 26 × 18 × 14 in once boxed. Foam over the lens face, support the housing so no weight ever reaches the mounting tabs, and put the whole thing inside a second carton. Snapped tabs lead the claim statistics and almost never come back from it.
6–12 lb packed. Charging follows the larger of scale and volume weight, so on a light bulky part the empty space is the expense.
Zone, speed, and how much padding the carton ends up holding. Kansas City, MO to Richmond, VA crosses a good many zones; a regional lane prices under this table and air well over it. The same box returned $25.83 through $37.24 on a single day. There is no flat headlight rate, so the calculator prices your route.
Plan on about 26 × 18 × 14 in packed. Cover the lens in foam, hold the housing so the delicate mounting tabs carry nothing, and use an outer carton around the inner one. Tab breakage is the damage claimed most often and it seldom repairs cleanly.
Usually 6–12 lb packed. Weigh and measure the sealed carton first, because the charge follows the scale or length times width times height over a carrier divisor, whichever is greater, and a low guess turns into an adjustment.
Those plastic mounting tabs protrude and give way under any concentrated pressure. Suspend the assembly in the middle of the carton on foam blocks that grip the body of the housing, leaving the tabs touching nothing.
Factory cartons are built for stacked pallets, not for a parcel moving alone through a sorter. Keep the original as the inner layer and surround it with a second box carrying 2 inches of cushioning.
Box size drives it far more than weight. A 26x18x14 inch carton bills at 47 lb dimensional weight even though the packed assembly weighs about 10 lb, and since the greater number is charged, headlight quotes catch people out. Distance and service speed account for the rest. Run your route and packed size through the calculator for live USPS, UPS, and FedEx pricing.
Ground with UPS or FedEx usually prices best at 47 lb billable. USPS also applies dimensional weight once a box passes one cubic foot, and this carton is several times that, so its small-parcel advantage disappears. Compare both ground networks on your own route, and buy at commercial rates online, which typically runs 20-40% under walk-up counter pricing for the same service.
Only with care. A smaller carton does cut dimensional weight, since the 47 lb figure comes straight from box volume, but headlights survive on padding depth and thin margins are a common reason they arrive cracked. Hold two to three inches of foam or crumpled paper on every face and around the tabs, and give up an inch of box only where that cushioning still fits.
