The Red Incandescent Trailer Identification Light Bar with 1258R Lights combines three compact red incandescent marker lamps on a black plastic mounting base, providing the traditional three-light configuration used for rear identification lighting.
This assembly is particularly useful as a replacement for older trailers and vehicles where maintaining the original incandescent appearance and lighting configuration is preferred over converting to LED.
Three 1258R Incandescent Lights
The defining feature of this identification bar is its use of three 1258R red incandescent marker lights.
The 1A-S-1258R is a compact rectangular marker/clearance lamp measuring 2-1/2" x 1-1/4" and using a single #194 incandescent bulb. The individual lamp is designed for 12V operation and uses a polycarbonate lens with an ABS housing.
That gives customers several ways to identify the assembly when searching for replacements:
- 1258R trailer light
- 1258R marker light
- 3-light trailer ID bar
- Red incandescent identification bar
- Three red trailer lights
- #194 bulb trailer light bar
Traditional Incandescent Lighting
Each 1258R fixture uses a replaceable #194 incandescent bulb rather than LEDs.
This traditional design is useful for customers looking to maintain an existing incandescent trailer-lighting system.
Incandescent lighting also allows individual bulbs to be serviced without automatically requiring replacement of the entire identification bar.
Black Plastic Base
The three red lights are arranged on a black plastic base, creating a complete identification-light assembly that can be mounted as one unit.
The black base provides a straightforward appearance suitable for many trailer, RV, and commercial vehicle applications.
Rear Identification Lighting
Three-light identification bars are commonly installed at the rear centerline of wide trailers and vehicles.
The three red-light arrangement is an especially recognizable trailer-lighting configuration, making this product searchable even when customers don't know the term "identification light."
Common searches include:
