HELLA 2307BULK Rear Marker Light Red LED 9 to 33V

HELLA 2307BULK Rear Marker Light Red LED 9 to 33V

Red LED rear position and marker light featuring a stealth clear-until-illuminated acrylic lens, fully sealed IP67 construction, nylon base, 2.5m pre-wired cable, and 5-year warranty — purpose-built for trucks, trailers, and heavy commercial vehicles requiring compliant rear marker illumination across 9–33V electrical systems.

Product Overview

The HELLA 2307BULK is a red LED rear marker light delivering rear position and marker lamp illumination for trucks, trailers, semi-trailers, and heavy commercial vehicles. Designed specifically as a rear position light, the 2307BULK produces red illumination through a stealth clear-until-illuminated acrylic lens — appearing completely clear and uncoloured when the light is off, and producing bright red rear marker output when powered on. This clean daytime appearance is a premium finish widely specified for modern truck builds, trailer fit-outs, and fleet refurbishment projects where a polished, uncluttered rear lighting profile is desired. The compact 60 x 38 x 32mm surface mount body is constructed with a nylon base for robust resistance against the knocks and impacts common in rear trailer and body panel environments, with the acrylic lens providing increased chemical resistance against fuel, cleaning agents, and road contaminants encountered in heavy transport operation. Fully sealed to IP67 against dust and moisture ingress, the 2307BULK is well suited to the exposed rear panel environments of trailers and truck bodies subject to rain, road spray, and pressure washdowns. Pre-wired with a generous 2.5m multi-core cable, the 2307BULK provides ample cable length for routing through trailer rear frames and body structures without requiring extension wiring. The 29mm centre-to-centre mounting distance is consistent with other HELLA marker lamps in the range, allowing uniform installation hardware across multiple marker light positions on the same vehicle. Universal 9–33V input ensures compatibility with both 12V and 24V vehicle electrical systems in a single unit, and HELLA's five-year warranty provides long-term confidence for fleet operators and trailer manufacturers.

Features & Benefits

Clear-Until-Illuminated Stealth Lens — The acrylic lens appears completely clear and uncoloured when the light is off, providing a clean and modern rear panel profile during daylight. When powered, the LED optics produce bright red rear position and marker illumination — a premium stealth finish widely specified for modern truck and trailer builds.

Red LED Rear Position Output — Delivers bright red rear marker and position lamp illumination with maintenance-free LED technology, providing a significantly longer operational lifespan than incandescent rear marker alternatives and reducing fleet downtime and replacement costs.

Acrylic Lens Construction — Increased chemical resistance compared to standard plastic lenses, protecting against fuel spills, oil, cleaning agents, diesel exhaust residue, and road contaminants that degrade standard marker light lenses over time on heavy vehicle rear panels.

Nylon Base Construction — Impact-resistant nylon base provides robust protection against the knocks and physical contact common in rear trailer and body panel environments, including loading bay and dock contact during reversing operations.

Fully Sealed IP67 — Fully dust-tight and protected against temporary water immersion, providing robust moisture and ingress protection for the exposed rear panel and body rail environments typical of heavy transport operation.

Pre-Wired 2.5m Multi-Core Cable — Generous 2.5m factory-fitted cable provides ample length for routing through trailer rear frames and body structures without requiring extension wiring or additional connectors at the light unit.

9–33V Universal Input — Single light unit compatible with both 12V light commercial vehicles and 24V heavy trucks and trailers, eliminating the need for separate voltage variants across mixed fleets.

Compact 60 x 38mm Surface Mount Profile — Low-profile surface mount design installs neatly onto trailer rear panels and body rails without excessive protrusion, maintaining a clean vehicle profile while delivering compliant rear marker illumination.

HELLA 5-Year Warranty — Backed by HELLA's five-year warranty, providing long-term confidence for fleet operators, trailer manufacturers, and transport companies specifying quality lighting for extended service life.

Frequently Asked Questions

What does "clear until illuminated" mean on the 2307BULK lens?

The 2307BULK uses a stealth optical design where the acrylic lens appears completely clear and uncoloured when the light is off, giving the rear panel a clean and modern daytime profile. When the light is powered on, the LED optics produce bright red rear position and marker illumination through the clear lens. This finish is popular with fleet operators and trailer builders seeking a polished, uncluttered rear appearance without compromising compliant red marker output.

Why does the 2307BULK use a nylon base rather than a polycarbonate or metal base?

Nylon offers a strong balance of impact resistance, chemical resistance, and lightweight construction well suited to rear trailer and body panel applications. The rear of trailers and truck bodies is frequently subject to physical contact during reversing, dock loading, and loading bay operations. A nylon base absorbs minor knocks and impacts more effectively than brittle materials, reducing the risk of cracking or shattering the mount under incidental contact.

How does the 2307BULK differ from the red lights in the 2053BULK side marker pack?

The 2307BULK is a dedicated rear position and marker light designed specifically for rear panel applications, featuring a clear-until-illuminated stealth lens, nylon base, and 2.5m cable suited to rear trailer frame routing. The red lights in the 2053BULK are side marker lights designed for side marking applications under ADR 45/01. Always select the correct part for the specific lighting function and mounting position to ensure compliance for your vehicle type.

Can this rear marker light be used on both 12V and 24V trailers?

Yes. The 2307BULK operates across a 9–33V input range, making it fully compatible with both 12V light commercial vehicle electrical systems and standard 24V heavy truck and trailer systems. A single light unit works across both voltages without modification, making it ideal for workshop and fleet use across mixed vehicle types.

How is the 2307BULK installed — does it require additional wiring hardware?

Each light comes pre-wired with a 2.5m multi-core cable, eliminating the need for connectors at the light unit itself. The generous cable length accommodates routing through trailer rear frames and body structures without extension wiring. Installation requires drilling a mounting hole to the 29mm centre-to-centre spacing, securing with fasteners through the surface mount base, and connecting the pre-wired cable into the trailer or vehicle rear wiring loom. Waterproof connectors, heat-shrink terminals, and rubber grommets are recommended for a fully sealed, professional installation on rear panels and body rails.
