Partsam LED backup lights, 7-inch

Key specifications

A dim or hard-to-see reverse light can make backing a bus, trailer or work vehicle less straightforward, especially when you need a surface-mounted replacement rather than a small add-on lamp. This Partsam set contains two round, white 7-inch LED backup lights with 36 LEDs in each light and a built-in reflex lens.

They run on 12V DC and are hard-wired, with a separate ground wire. Screws and thick mounting gaskets are included, so the package covers the stated mounting hardware as well as the lights.

The wiring has three functions: white is ground, black is the dimmer tail/running-light connection, and red is the brighter reverse-light connection. The lights are sealed and rated IP65 for water resistance. That does not make them suitable for submersion, the listing specifically says not to use them underwater.

One detail deserves attention before ordering: the product name includes “Amber”, while the description identifies the lights as white. If lamp colour matters for your replacement, confirm the version being offered rather than relying on the title alone.

Who it’s for

These are aimed at vehicles or equipment with a 12V DC supply and room for a 7-inch round surface-mount light. The listing names transit and school buses, trucks, vans, utility vehicles, trailers and boats among possible applications. That is a broad list, not confirmation that the lamps will fit every model: mounting space, wiring and the vehicle’s existing light arrangement still matter.

Es buena opción si you need a pair of round reverse lights, want a reflex lens built into the lamp, and can work with separate hard-wired connections. The included gaskets and screws may also be useful when replacing a surface-mounted light where the mounting hardware needs to be supplied with the lamp.

Puede no ser la mejor opción si you need a flashing light pattern straight out of the box, a plug-in connector, or a lamp for underwater use. The description says there is no flashing pattern, though a suitable relay can be used to make the lights flash. This is a wiring project, not a ready-made warning beacon.

Everyday use

Picture reversing a utility trailer into a driveway at dusk: the red wire powers the brighter reverse-light mode, while the reflex lens provides a passive reflective element when light reaches it. For a vehicle that also uses the lamp as a running or tail light, the black wire is identified for the dimmer mode. That dual-function wiring is useful, but it also means installation should follow the intended circuit connections rather than treating the lamp as a simple two-wire replacement.

Compared with a basic single-purpose backup lamp, these offer a separate dimmer connection and built-in reflex lens. A buyer looking for a dedicated flashing safety light or a fully plug-and-play replacement would be choosing a different setup. According to the manufacturer, the lamp is sealed and IP65-rated, but the stated limit against underwater use is important for boat or trailer owners.

Antes de decidir

What comes in the package? Two lights, screws and thick mounting gaskets are listed. No other installation parts are specified.

Do they flash? Not by themselves. The description says they have no flashing pattern, a suitable relay is needed for that function.

Can they be used underwater? No. They are described as IP65 waterproof, but the listing expressly warns against underwater use.

Veredicto final

Choose this pair if your vehicle uses 12V DC, has space for a 7-inch round surface mount and you want hard-wired reverse lights with a separate dimmer connection and reflex lens. The included mounting pieces make the package more complete than a bare lamp, but the wiring still needs to match your setup. Skip it if you need a confirmed amber colour, a built-in flasher, or submersible lighting, the colour wording in the product name and description does not agree, so that point needs resolving before purchase.
