The 3.9" Red Clear-Lens 12-Diode LED Marker Light combines a slim exterior profile with 12 red LED diodes and a clear lens, providing a clean modern appearance for trailer, RV, truck, and commercial vehicle marker-light applications.
At 3.9 inches, this fixture falls into a popular compact rectangular marker-light size. Similar 3.9-inch lights are widely used as marker and clearance lamps on trailers, RVs, campers, trucks, and commercial vehicles.
The combination of 3.9-inch size + red illumination + clear lens + 12 diodes gives customers several specific characteristics to search for when replacing an existing light.
12 Red LED Diodes
This fixture features 12 LED diodes producing red illumination.
LED technology provides several advantages for marker and clearance lighting:
- Instant illumination
- Low power consumption
- Long service life
- Reduced maintenance
- No traditional incandescent filament
The 12-diode configuration is also an important replacement specification for buyers trying to match an existing fixture.
Clear Lens with Red Illumination
This model should be clearly identified as:
Lens Color: Clear
Illuminated Color: Red
The clear lens provides a clean appearance when the fixture is off while allowing the LEDs to produce red illumination when energized.
Clear-lens red marker lights are a common configuration in this general 3.9-inch trailer-light category.
3.9-Inch Replacement Marker Light
The 3.9-inch size is one of the strongest SEO characteristics of this product.
Customers frequently search for replacement trailer and RV lights by physical dimensions rather than manufacturer part numbers. Searches worth targeting include:
- 3.9 inch red marker light
- 4 inch red trailer marker light
- 3.9 inch LED clearance light
- 12 LED trailer marker light
- Clear lens red marker light
- Rectangular red trailer light
- RV side marker light
- Replacement trailer clearance light
For SEO purposes, including both 3.9-inch and approximately 4-inch search terminology can help capture buyers measuring an existing fixture themselves.
Marker & Clearance Light Applications
This fixture is designed for marker and clearance-light applications where red illumination is appropriate.
Potential uses include:
- Trailer marker lighting
- Trailer clearance lighting
- Rear-side marker lighting
- RV marker lighting
- Motorhome clearance lighting
- Truck body marker lighting
- Commercial vehicle lighting
- Equipment trailer lighting
Red marker lighting is particularly relevant to compatible rear and rear-side positions. Final placement should match the vehicle configuration and applicable lighting requirements.
