The 3-7/8" Red Clear-Lens 14-Diode Marker & Clearance Light provides bright, efficient LED exterior lighting in a compact format for trailers, RVs, trucks, and commercial vehicles.
Featuring 14 red LED diodes, this fixture produces red illumination through a clear lens, creating a clean appearance when unlit while maintaining the red illuminated output needed for compatible marker and clearance-light applications.
The combination of its 3-7/8-inch size, 14-diode configuration, red illumination, and clear lens gives customers several useful specifications for identifying a replacement light—even when they do not know the original manufacturer or part number.
14 Red LED Diodes
This marker light uses 14 LED diodes to produce red illumination.
LED technology provides several practical benefits for vehicle marker lighting:
- Instant illumination
- Low power consumption
- Long service life
- Reduced maintenance
- No traditional incandescent filament
The 14-diode configuration is also an important visual and technical characteristic for matching an existing trailer, RV, or truck marker light.
Clear Lens with Red Illumination
This product should be clearly distinguished as:
Lens Color: Clear
Illuminated Color: Red
The clear lens provides a cleaner appearance when the light is off, while the red LEDs provide red illumination when powered.
This distinction is especially important for replacement applications because a clear-lens/red-LED fixture may look substantially different from a traditional red-lens marker light when unlit.
3-7/8-Inch Replacement Size
The 3-7/8-inch size is an important SEO and replacement specification.
Customers often measure their existing marker light rather than search by an OEM or manufacturer part number. Because 3-7/8" is very close to 4 inches, buyers may also search using approximate phrases such as “4 inch marker light.”
For SEO purposes, both measurements are valuable, but the actual product dimension should remain listed as 3-7/8 inches.
Strong searches include:
- 3-7/8 inch red marker light
- 3 7/8 red LED marker light
- 3.875 inch marker light
- 4 inch red marker light
- 14 LED marker light
- 14 diode marker light
- Clear lens red marker light
- Red LED trailer marker light
- RV clearance light
- Replacement trailer marker light

Red Marker & Clearance Applications
Red marker and clearance lights are generally associated with compatible rear and rear-side vehicle positions.
This makes the light a potential replacement for red marker and clearance fixtures on trailers, RVs, trucks, and similar vehicles.
Exact placement requirements depend on vehicle type, dimensions, installation position, orientation, and applicable vehicle-lighting requirements.
Strong Replacement-Light Search Profile
This light has four highly useful identifying characteristics:
3-7/8" SIZE + 14 LEDs + RED ILLUMINATION + CLEAR LENS
For customers who do not know their existing light's part number, those specifications provide several ways to locate the product.
We should deliberately target both the exact 3-7/8" dimension and the approximate 4-inch search because customers may measure or describe the same size differently.
Important Fitment Note
Before ordering, verify:
- 3-7/8-inch overall size
