An A0658685000 headlight switch search should begin with the reference on your original control. The NexuParts listing also identifies A9065450104 and describes a Mercedes-Benz truck application. These are useful search details, but they do not form a complete vehicle fitment table. Before ordering, compare the original reference, connector, controls, and mounting features, and keep any unanswered vehicle-specific question separate from a confirmed match.
A0658685000 headlight switch: the listed facts
The A0658685000 / A9065450104 Mercedes-Benz truck headlight switch is described as a new aftermarket replacement. Its stated package contains one headlight switch. The product title names Mercedes-Benz Truck, but the reviewed description does not supply a model-by-model or year-by-year application list. Do not extend that broad truck description to a particular vehicle without checking its original part and configuration.
The store SKU is SD-A0658685000-849197949212. Use that identifier to help locate this catalog item in an order or support request. For the replacement comparison, use the actual references A0658685000 and A9065450104 rather than treating every number in the SKU as a manufacturer part number. A product link is also useful because it identifies the exact listing under discussion.
How to read the two-reference listing
The page associates A0658685000 and A9065450104 with this item. It does not provide a manufacturer supersession history or specify how the references map to individual truck configurations. If your original shows either reference, continue with the physical and application checks. If it shows another number, ask about that difference instead of assuming that a similar number is interchangeable.
Record the complete marking, including any letters or suffixes. When a character is unclear, send a readable photograph and identify the uncertainty. Do not complete a partly visible reference from memory or from the product title. An exact-looking transcription is only useful if it accurately reflects the component you are replacing.
Separate the symptom from the selection
Intermittent control response, a control that does not respond, or visible damage may prompt you to look for a replacement. The product description discusses control-response concerns, but a symptom does not establish the cause on your vehicle. A product listing cannot determine whether this switch is responsible for a lighting problem.
If the fault has not been identified, seek appropriate professional diagnosis before buying a component. Write down what you observed and which control was involved. This guide helps organize a buying comparison; it is not an electrical test procedure, a wiring guide, or a promise that a new switch will resolve a particular fault.
Build a four-part fitment record
Vehicle and original reference
Gather the vehicle model, year, relevant configuration information, and the complete original part reference. The listing's broad brand description does not settle those application details. Keep a clear picture of the original marking with your notes. If you obtain fitment confirmation, retain that response with the product link so the item you eventually order remains unambiguous.
Connector and terminal arrangement
Compare the connector outline, its orientation, retaining features, and visible terminal arrangement with the listing photographs. The description asks buyers to check pin count but does not state a numeric pin specification. Do not borrow a count from another headlight switch. If the relevant image is missing or unclear, request a better comparison before purchasing.
This guide also does not establish an operating voltage or wiring assignment. A truck application label should not be used to invent an electrical specification. Resolve any electrical compatibility question through appropriate vehicle-specific information rather than planning to adapt an uncertain connector.
Controls and visible markings
Compare the control layout and visible markings against the original. Record any difference in the arrangement or appearance of the controls. Do not infer additional functions from a similar switch or a broad description of lighting control. The reviewed details do not provide a complete equipment-function matrix, so an unlisted feature should remain a question rather than an assumption.
Housing, mounting, and position
Review the housing outline and mounting features as well as the outward-facing surface. The description directs buyers to match the original position rather than giving a detailed installation-location specification. Compare the original attachment points and surrounding shape with the product images. A familiar face alone cannot resolve an uncertain underside or mounting detail.
Keep related headlight switches separate
The store also lists a 15194803 / 19381535 Chevrolet GM headlight switch. It belongs to the same general product category, but it has different references and a different stated vehicle application. It is linked here as a contrasting headlight-control listing, not as a substitute for the Mercedes-Benz truck item.
Browsing the Lighting & Electrical parts collection can help you locate controls by reference. Category membership does not establish compatibility between them. If search results show several similar controls, compare their individual references and application notes before considering price or appearance.
Ask a focused question before checkout
A useful fitment request includes the product link, original reference, vehicle details, and clear photographs of the connector and mounting features. Explain the precise point you cannot verify: a suffix difference, an unclear terminal arrangement, or a control marking that does not match. Provide your VIN through the store's fitment-help contact channel when vehicle-specific clarification is needed.
Keep unresolved items on your checklist until they have an answer. Review the current product page for price, availability, package contents, and purchase terms before ordering. This guide does not preserve a price quote, provide a delivery guarantee, or add installation requirements that are absent from the reviewed listing.
Frequently asked questions
Is this an official Mercedes-Benz product?
No. The listing describes an aftermarket replacement, not an official brand product. The brand name identifies the stated compatibility context and is not a claim about who manufactured the replacement.
Does the package contain other lighting components?
The stated package contains one headlight switch. Do not assume lamps, wiring, trim, or additional hardware are included unless the current listing explicitly says so.
Can the truck label confirm my specific application?
No complete fitment conclusion follows from that label alone. Confirm your original reference and configuration, then compare the connector, controls, and mounting details before purchase.
What should I do before installation?
Compare the received item with the original and your saved photographs. If anything differs, contact the store before fitting or modifying it. This article does not supply removal steps or wiring changes.

Return to the A0658685000 / A9065450104 replacement switch page once the open questions are resolved. Choose an A0658685000 headlight switch using a confirmed reference and physical comparison, not a broad brand match or a similar photograph alone.
