The Shangyuan B07WTP3K72 is a two-pack of white auxiliary LED flood lights listed for 10–35 V DC systems. It may suit a properly designed docking, deck, T-top or spreader-light circuit on a 12 V or 24 V boat, but it is not a verified replacement for required navigation lights. Before buying, confirm the circuit design, mounting position, glare control and the documentation you need for the intended use.
The gallery is tied to the current white B07WTP3K72 variant. Promotional statements shown in seller images are not independent test results.
Shangyuan white marine flood lights, two-pack
Best suited to: Owners who need compact auxiliary flood lighting and can design a compatible protected circuit and glare-controlled mounting position.
Main limitation: The listing does not provide verified navigation-light certification, a complete installation manual, a current-draw diagram or salt-spray test evidence.
Confirm ASIN B07WTP3K72 and the white two-light variant before checkout.Quick verdict
This pair is worth considering as auxiliary close-range lighting when the boat owner can verify the electrical installation and aim the flood beam without hiding navigation lights or degrading night vision. Skip it when the job requires a certified navigation-light replacement, documented corrosion performance, a plug-and-play harness, or complete model-specific installation instructions.

Use-case decision table
| Intended job | Fit assessment | What to verify first |
|---|---|---|
| Docking-area illumination | Potential fit | Aim, glare at the helm, nearby traffic and a switched protected circuit |
| T-top or spreader lighting | Potential fit | Bracket support, cable routing, overhead glare and water entry at penetrations |
| Deck or work lighting | Conditional fit | Low-glare placement that preserves night vision and does not mask required lights |
| Required navigation light replacement | Do not assume fit | Use a light documented for the required color, arc, intensity, position and application |
| Permanent saltwater exposure | Evidence gap | Corrosion, salt-spray, connector and warranty documentation for the exact product |
Electrical compatibility is more than voltage
The 10–35 V DC listing range covers nominal 12 V and 24 V boat systems, but that alone does not make the installation compatible. The product page does not provide a complete current-draw table, conductor-size instruction, fuse specification or wiring diagram for the delivered kit. Those values should not be guessed.
Confirm the exact light load and follow the boat, switch, protection-device and product instructions. Route conductors away from heat, sharp edges, moving hardware and standing water. If the required conductor size, overcurrent protection or connection method is unclear, use a qualified marine electrician rather than adapting a general automotive-light installation.
Mounting and aiming checks
- Choose an auxiliary-light job before choosing the mounting point.
- Dry-fit both brackets and check clearance through their full aiming range.
- Confirm that fasteners and any deck or T-top penetration are suitable for the structure.
- Plan sealed cable entry and strain relief without relying on the product's IP claim to protect a poor installation.
- Aim the flood beam below the operator's direct sightline and away from reflective rails, windshields and spray.
- Test the final setup from the helm and from outside the boat at night.
A 60-degree flood pattern is intended for broad nearby illumination rather than a narrow long-distance beam. That may help while docking or working on deck, but it also increases the importance of glare control. Bright foreground light can reduce the operator's ability to see darker water beyond it.
Do not treat auxiliary flood lights as navigation lights
The U.S. Coast Guard Navigation Rules require prescribed lights to meet specific characteristics and warn that other lights must not be mistaken for them, impair their visibility or distinctive character, or interfere with a proper lookout. The Coast Guard also cautions that replacement or decorative LED lighting may be improper when technical certification requirements are not met.
No navigation-light certification was verified for this ASIN. Do not use the seller's words “stern,” “anchor” or “navigation” as proof that the white flood-light pair satisfies a required light's arc, intensity, position or certification. Keep properly documented navigation lights separate and visible.
Freshwater and saltwater considerations
For freshwater use, inspect the lens, housing, bracket, cable entry and fasteners after installation and after impacts or adjustment. For saltwater use, the seller's IP67 claim addresses water and dust ingress, not galvanic compatibility or salt-spray corrosion life. No salt-spray standard or model-specific corrosion test was found.
Choose compatible mounting hardware, isolate dissimilar metals where the boat or product instructions require it, and inspect for coating damage and corrosion. Rinsing and inspection may help maintenance, but they do not turn an undocumented component into a certified saltwater product.
Meaningful strengths
- The seller-listed 10–35 V DC range covers common nominal 12 V and 24 V systems.
- The package provides two matching white flood-light assemblies.
- The compact aluminum housings and adjustable brackets may suit limited mounting spaces.
- The wide flood pattern is more relevant to close-range docking and deck tasks than a narrow spot beam.
Important limitations
- All output, color-temperature, beam and IP figures remain seller claims.
- No independent photometric, ingress, corrosion or lifespan test was reviewed.
- No complete installation manual, current-draw table, fuse specification or cable-size instruction was verified.
- No certification was verified for use as a required navigation light.
- Price, availability, rating, review count and popularity are intentionally excluded.
- No hands-on brightness, waterproofing, vibration or durability test is claimed.
When another light type is a better choice
Choose a documented marine spreader or work light when you need manufacturer installation data, current draw, a defined beam pattern and corrosion evidence. Choose a certified navigation-light product when replacing a required sidelight, masthead light, sternlight or all-round light. For cockpit or deck use near the helm, a lower-output shielded fixture may preserve night vision better than a forward-facing flood light.

Use the boat electronics guides to plan power and mounting with the rest of the system. Review the boat safety equipment guide before a night trip, and use the battery runtime calculator only after you have a verified load value. The Botepon red-and-green strip-light review covers a different 12 V product and explains why auxiliary lighting should not be confused with required navigation lights.
Frequently asked questions
Are the Shangyuan lights a replacement for required navigation lights?
No replacement-light compliance documentation was verified for ASIN B07WTP3K72. Treat the pair as auxiliary flood lights, and do not let them obscure required navigation lights or interfere with a proper lookout.
Will these lights work on a 12-volt or 24-volt boat?
The current product listing specifies a 10–35 V DC input range, which includes nominal 12 V and 24 V systems. The complete circuit still needs suitable switching, wiring and overcurrent protection for the boat and installation.
Does IP67 prove the lights are suitable for saltwater use?
No. IP67 is the seller's ingress-protection claim. It does not by itself establish salt-spray resistance, corrosion life, wiring quality or long-term sealing after installation.
Has BoatOwnerHub tested the Shangyuan docking lights?
No. This review checks the exact Amazon listing, supplied product images and authoritative Coast Guard lighting guidance. It does not claim hands-on output, waterproofing, corrosion or durability testing.
