The 4" x 2" Amber 3-SMD LED Marker & Clearance Light combines efficient LED illumination, a built-in reflector, and extended 18-inch leads in a practical rectangular format for trailer, RV, truck, and commercial-vehicle applications.
Featuring 3 amber SMD LEDs, this fixture provides amber illumination for compatible marker and clearance-light positions. The integrated reflector adds passive visibility when the light is not powered, while the 18-inch leads provide additional wiring length for installation.
The 4" x 2" reflectorized marker-light format is an established trailer-lighting configuration. Comparable lights use an integrated reflex reflector specifically to combine marker/clearance lighting and passive reflectivity within one fixture.
3 SMD LED Design
The fixture features 3 SMD LEDs producing amber illumination.
LED technology provides practical advantages for exterior marker lighting, including:
- Instant illumination
- Low power consumption
- Long service life
- Reduced maintenance
- No traditional incandescent filament
The specific 3-SMD configuration also gives customers an additional specification for matching an existing trailer, RV, or truck marker light.
Built-In Reflector
A major feature of this light is its integrated reflector.
Rather than requiring the lighting and reflector functions to be handled by two separate components, the reflector provides passive reflectivity when illuminated by another vehicle's headlights, while the LEDs provide active amber illumination when powered.
Integrated reflex reflectors are commonly incorporated into this style of trailer marker and clearance light.
This also gives us valuable search terms such as:
- Marker light with reflector
- Reflectorized trailer marker light
- Amber clearance light with reflector
- LED trailer light with built-in reflector
- 4 x 2 reflector marker light
18-Inch Wire Leads
The 18-inch leads provide useful additional wiring length when installing or replacing the fixture.
The extended leads can make installation easier when:
- Wiring connections are located behind a body panel
- Existing vehicle wiring needs to be reached
- The light is installed on an RV exterior wall
- Connections need to be routed inside a trailer body
- Additional wire length is useful for serviceability
Wire functions and polarity should be verified before making the final electrical connections.
4" x 2" Replacement Size
The 4" x 2" size is especially valuable for replacement-light searches.
Customers often identify an existing trailer or RV marker light by measuring the fixture rather than searching by its original manufacturer or part number.
High-value searches include:
- 4 x 2 amber marker light
- 4 inch amber trailer light
- 4 x 2 LED clearance light
- 3 LED amber marker light
- Amber trailer light with reflector
- Rectangular amber marker light
- RV clearance light with reflector
- Replacement trailer marker light

Strong Replacement-Light Search Profile
This light has several highly useful identifying characteristics:
4" x 2" + AMBER + 3 SMD LEDs + BUILT-IN REFLECTOR + 18" LEADS
That combination makes it particularly relevant for customers searching for an existing trailer or RV light without knowing its original part number.
Amber Marker & Clearance Applications
Because this fixture produces amber illumination, it is particularly relevant for compatible front and forward-side marker and clearance-light positions.
The reflector provides an additional passive visibility component, while the LEDs provide the active marker/clearance-light function.
Exact placement and regulatory requirements depend on the vehicle type, dimensions, mounting position, orientation, and applicable lighting requirements.
Important Fitment Note
Before ordering, verify:
- 4" x 2" fixture dimensions
- Overall fixture depth
- Existing mounting footprint
- Required mounting style
- Mounting-hole spacing
- Vehicle operating voltage
- 18-inch lead length
- Wire count
- Wire functions and polarity
- Lens color
- Available installation clearance
- Required marker/clearance-light position
The exact lens color, voltage, mounting style, wire count/colors, housing material, fixture depth, mounting-hole spacing, IP rating, and regulatory certifications have not been supplied. Similar 4" x 2" reflectorized marker lights are available with different mounting and electrical configurations, so those specifications should not be assumed.
