LED Stop/Tail/Turn Lamp 44350C

Rear lighting module in one LED housing

Truck-Lite combines stop, tail, and turn functions in the 44350C LED lamp aimed at Class 8 tractors and trailers that want brighter rear signaling without juggling three separate incandescent buckets. LED modules draw less current than legacy bulbs, but ground paths and connector corrosion still decide whether a lamp looks bright on the bench yet dims on the truck.

Listed price is $42.60 USD before tax. Weight is 1.1 lb, so a pair of rears fits a routine parcel restock. Tax applies per ship-to state before dispatch.

Lamp function check on the truck

After install, verify stop, tail, and turn independently with a helper or a diagnostic switch panel. A lamp that flashes turn but never illuminates stop often traces to a mis-pinned connector or a multiplexed chassis that expects a specific LED load.

Compare lens markings and pigtail keying to the removed lamp before you drill new holes. Adapters exist in the market; this listing assumes the Truck-Lite footprint your table row describes.

• Test with the engine running and lights loaded to catch low-voltage dimming.
• Inspect grommets for pinch when the box twists on a rusty bracket.
• Seal wire entries against pressure-washer spray common in fleet washes.
• Log left and right serial labels if your safety audit requires it.

Make coverage on the card

Fitment chips name Freightliner, Kenworth, Peterbilt, and Volvo applications summarized in the table above. Lamp bases and pigtail lengths still vary by year and rear fairing design.

Verify using the part marking on the removed lamp, harness connector photos, and VIN when available. We do not promise a match from make badges alone.

Send connector photos to support@aonetruckauto.com or use the contact form. The fitment guide helps compare adjacent Truck-Lite listings.

Ordering reference

Purchase orders citing Truck-Lite 44350C should still be validated against the stamp on the old lens housing. Cart and PayPal use SKU the cart listing at the published unit price.

Electrical hygiene

Dielectric grease on pins is fine when the connector maker allows it; avoid packing sockets until pins cannot seat. Repair splices belong in heat-shrink, not twisted wire under electrical tape that traps moisture.

LED lamps can fail from reverse polarity during a hurried mid-trailer splice. Use a meter before energizing a newly repaired harness.

Receiving and returns

Inspect lenses for crack lines after transit. Opened lamp assemblies may fall under restricted return rules on returns and refunds; read that page before buying spares on speculation.

Trailer and tractor rear circuits

Rear lamps see more road splash than cab markers. Connectors sitting in wheel spray need boots intact and drains clear so water does not pool at the lowest pin.

When a tractor pulls multiple trailers, verify which rear lamp is active on the power unit versus the trailer ABS module. Multiplexed systems can route stop through a different pin than older harnesses.

LED load draw differs from incandescent; some older flasher modules need electronic flashers when you convert a whole lane. Watch for hyperflash that drivers ignore until citation season.

Inspection lane documentation

Fleet safety audits often photograph rear lamp function during PM. Record test results on the work order when you replace both sides so the next audit sees a date stamp.

Pair replacement when one side shows moisture inside the lens; the sibling unit usually follows within weeks.

Parcel restock economics

At $42.60 per lamp, keeping four units on the shelf beats overnight freight on a Friday evening breakdown. Weight at 1.1 lb keeps shipping in parcel class for most destinations per published policy.

Corrosion mapping on rear harnesses

Map green corrosion by pin number on a sketch when you open a failed connector. Fleets that run de-ice chemistry see pin seven and ground paths fail first on some harness generations.

Heat-shrink butt splices belong outside the splash zone when repairs are unavoidable. Move splices up the frame where the harness stays dry under normal wash routines.

Night pre-trip behavior

Drivers doing night pre-trips spot dim stop output faster than yard staff. Teach them to compare brightness side to side rather than only checking that a lamp glows at all.

Fleet color and lens standards

Some fleets standardize red tail lens shade across brands so a mixed trailer pool still looks uniform in the yard. Compare lens hue in daylight when aesthetics matter to customer-facing units.

When refurbishing crash damage, replace lamp brackets that bent slightly; LED modules mount stiffly and crack solder joints if the housing twists every time the gate closes.

Document amp draw on a meter when stop function looks weak; low voltage upstream shows as dim LEDs even with a new lamp installed correctly.

Rear electrical reliability

Rear harnesses on drop-frame tractors flex at the frame kick; inspect loom support clamps when replacing lamps repeatedly on the same VIN.

LED stop function must exceed minimum brightness your safety team defines; compare side to side with a helper standing fifty feet aft.

Truck-Lite rear modules simplify wiring when grounds are remade to bright metal during every lamp change, not only when corrosion is obvious.
