Shopping for a 15194803 headlight switch starts with the number on the original part, not just a Chevrolet or GM name in a search result. NexuParts lists an aftermarket headlight switch under reference numbers 15194803 and 19381535. Before ordering, compare those references with the original switch, then check the connector, controls, housing, and mounting position. A familiar-looking front panel alone is not enough to confirm a match.
This guide explains what the listing establishes, what still needs checking on your vehicle, and how to organize the details for a useful fitment question. It does not provide a vehicle-specific diagnosis or an installation procedure.
What the 15194803 headlight switch listing confirms
The 15194803 / 19381535 aftermarket headlight switch is listed for compatible Chevrolet GM applications. The product description identifies it as a headlight switch and states that the package contains one switch. It is an aftermarket replacement, not an official Chevrolet or GM branded product.
The listing does not establish a specific model-year range or a universal fit across Chevrolet and GM vehicles. It asks buyers to verify the original reference, plug type, pin count, button layout, and mounting position. Treat that request as a checklist to complete before purchase, rather than assuming that the brand name settles compatibility.
Start with a readable reference number
Record the reference printed or labeled on your original switch exactly as it appears. Keep a clear photograph as well as a typed note so that a missing digit or an unclear character can be reviewed. For this product, the stated reference numbers to investigate are 15194803 and 19381535.
Keep the vehicle details separate from the part details. Your vehicle year, make, model, and trim describe the application; the switch reference identifies the part you are trying to compare. Supplying both is more useful than asking whether a switch fits a Chevrolet without any additional information.
If the number is unreadable or different, do not turn a visual resemblance into a fitment conclusion. Gather photographs and request clarification before ordering. These two references appear together in this listing, but that is not a substitute for checking your particular application.
Compare the connector, controls, and mounting details
Once you have the reference, use the product photographs to make a structured comparison. The listing does not specify an exact contact count, so this guide does not assign one. Compare what is actually present on the original part and seek a clearer product view when a detail is hidden.
- Connector shape: Compare the outline, orientation, and visible locating features of the plug connection.
- Contacts: Record the visible pin or contact arrangement without guessing about anything obscured in a photograph.
- Controls: Compare the number, positions, and markings of the buttons or other controls shown.
- Housing: Look at the overall shape and the relationship between the front panel and the rear connection.
- Mounting position: Compare visible clips, tabs, and the original location. A similar face does not confirm matching mounting details.
Do not plan to modify a connector or mounting feature to resolve a mismatch. If any comparison is uncertain, pause the purchase decision and ask for confirmation using the specific detail that differs.
Describe the problem without treating it as a diagnosis
You may be investigating a control that responds intermittently or does not respond as expected. Write down what you observe and which control is involved. Keep that symptom description separate from the fitment check: an operating complaint does not establish that this particular replacement is the correct part.
The product listing alone cannot identify the cause of a vehicle's lighting problem. If the fault has not been diagnosed, have it assessed before buying a switch solely because its name matches the symptom. This article makes no claim that replacing the switch will resolve a specific fault.
Why the 15926098 listing needs its own check
NexuParts also carries a 15926098 headlight switch listed for GM Chevrolet. It is a related product because it belongs to the same part category and broad vehicle-brand context. It uses a different stated reference number.
15926098 is not presented here as a confirmed substitute for 15194803 or 19381535. Compare it only if the original part information gives you a reason to investigate that reference. Choosing between the listings should depend on verified application and physical details, not on which photograph looks closest at a glance.
For broader browsing, the Lighting & Electrical parts collection groups related products. Category membership helps you navigate; it does not mean that every switch in the collection is interchangeable.
A practical checklist before checkout
Keep the following notes together so you can make a deliberate buying decision or send a focused fitment inquiry:
- Vehicle year, make, model, and trim, plus the original switch's reference number.
- Clear photographs of the original front panel, rear connector, and visible mounting features, if available.
- The product link you are considering and any specific detail that does not appear to match.
- Confirmation that one aftermarket headlight switch is the item you intend to order.
- A final review of the live product page and current store policies before checkout.
When the part arrives, compare it with the original before installation. If a reference, connector, control layout, or mounting detail differs, contact the store before fitting or modifying it. This comparison is a buying safeguard, not an installation instruction.
Frequently asked questions
Does the Chevrolet GM wording confirm my model and year?
No. The wording is broad, and the listing does not provide a specific year range. Verify your vehicle details, original reference, connector, controls, and mounting position before ordering.
Is this a genuine Chevrolet or GM switch?
No. NexuParts describes it as an aftermarket replacement. Vehicle-brand names describe the intended compatibility context, not the manufacturer of the replacement part.
Does the package include more than one switch?
The product description states one headlight switch. Do not interpret the two reference numbers in the title as two separate switches in the package.
What if the original number is 15926098?
Review the separate 15926098 listing and complete its fitment checks. This guide does not confirm interchangeability between that reference and the 15194803 / 19381535 listing.
Choose from verified details, not a broad brand match
A useful search becomes a better purchase decision when you have the original number and physical details ready. Review the 15194803 headlight switch product details and photographs, compare the listed 19381535 reference where relevant, and resolve any uncertainty before checkout.
