3-7/8" x 2" Red 14-LED Marker & Clearance Light – 12V, 2-Wire

1A-S-68R Red 14-LED Marker & Clearance Light provides a compact, durable LED lighting solution for trailers, RVs, trucks, and commercial vehicles.

Unlike the clear-lens version 1A-S-68RI, the 1A-S-68R uses red LEDs with a red lens. Current catalog identifies this model as part of its 14-diode LED marker lamp family, measuring 3-7/8" x 2", with a 2-bare-wire connection and operation tested at 12V.

14 Red LED Diodes

The light uses 14 light-emitting diodes, providing efficient red illumination for compatible marker and clearance-light applications.

LED technology provides several practical advantages over traditional incandescent marker lighting:

• Instant illumination
• Low power consumption
• Long service life
• Reduced maintenance
• No traditional incandescent filament

Red Lens + Red LED Configuration

The 1A-S-68R is specifically the red-lens/red-LED version of this light family. The related 1A-S-68RI is the clear-lens/red-LED version, which makes the part number particularly important when customers are replacing an existing fixture.

3-7/8" x 2" Compact Design

The lamp at 3-7/8" x 2", while another distributor lists its complete dimensions at approximately 3.875" L x 2" W x 1" H.

The design is also commonly described as a “hump back” style marker light, which gives us another useful search phrase for customers trying to identify an existing fixture by appearance.

2-Wire Connection

The 1A-S-68R uses two bare-wire connections, making the wiring configuration another useful specification for replacement searches.

Customers replacing an existing light should verify the vehicle-side wiring and polarity before making final electrical connections.

Strong Replacement-Light Search Profile

Now that we have the exact part number, this page can target much more specific searches:

1A-S-68R + 3-7/8" x 2" + 14 LED + RED LENS + 2 WIRE + 12V

Those specifications are particularly valuable for customers replacing an existing RV or trailer marker light.

1A-S-68R vs. 1A-S-68RI

This distinction is important for customers:

1A-S-68R: Red LEDs + Red Lens
1A-S-68RI: Red LEDs + Clear Lens

Both belong to Kaper II's 14-diode marker-light family, but they have different lens appearances.
