HELLA 2146-H24 Rear Indicator Module LED 9 to 33V

HELLA 2146-H24 Rear Indicator Module LED 9 to 33V

24-LED Multivolt rear indicator module with Ultra Wide Visibility Optics, IP67 sealed construction, ADR 6/00 Category 2a compliance, and 6W efficient operation, purpose-built to upgrade existing surface mount Jumbo or Designline combination lamps to LED technology across 9–33V electrical systems.

Product Overview

The HELLA 2146-H24 is a dedicated LED rear indicator module designed specifically to upgrade existing surface mount Jumbo or Designline series combination lamps from incandescent to LED technology without replacing the entire lamp housing. This makes the 2146-H24 a highly cost-effective and practical solution for fleet operators and transport companies managing large trailer inventories fitted with existing HELLA Jumbo or Designline housings, allowing a targeted LED upgrade of the indicator function while retaining the existing lamp body and mounting arrangement. The 24 high-performance LEDs are arranged with HELLA's UWVO (Ultra Wide Visibility Optics) technology, delivering improved side visibility beyond the standard forward-facing visibility cone of conventional indicator modules. UWVO optics increase the horizontal visibility angle of the indicator, making the 2146-H24 more visible to adjacent traffic, pedestrians, and road users approaching from the side, improving active safety during lane changes and turning manoeuvres on heavy vehicles. ADR 6/00 Category 2a compliance confirms the module meets the legal requirements for rear indicator lamp functions on heavy vehicles operating on Australian public roads. At just 6W power consumption, the 2146-H24 operates at a fraction of the draw of equivalent incandescent indicator lamps, reducing the electrical load on trailer circuits and extending the life of trailer wiring and connectors. The Multivolt 9–33V input range covers standard 12V and 24V heavy vehicle electrical systems in a single module without requiring voltage-specific variants. Fully sealed to IP67 against dust and moisture ingress, the module is pre-wired with 200mm of cable for connection into the existing lamp housing wiring, and the 195 x 125 x 35mm surface mount footprint is engineered to fit directly into compatible Jumbo and Designline lamp housings. HELLA's five-year warranty provides long-term confidence for fleet operators and trailer manufacturers specifying this LED upgrade module.

Features & Benefits

Purpose-Built LED Upgrade Module: Designed specifically to replace incandescent indicator modules in existing HELLA Jumbo and Designline surface mount combination lamp housings, enabling a targeted LED upgrade of the indicator function without replacing the entire lamp assembly and associated mounting hardware.

24 High-Performance LEDs: Twenty-four individual high-performance LEDs deliver bright, consistent amber indicator illumination with maintenance-free LED technology, providing a significantly longer operational lifespan than the incandescent modules they replace.

UWVO Ultra Wide Visibility Optics: HELLA's Ultra Wide Visibility Optics technology extends the horizontal visibility angle of the indicator beyond the standard forward-facing cone, improving side visibility to adjacent traffic, pedestrians, and road users approaching from the side during lane changes and turning manoeuvres.

ADR 6/00 Category 2a Compliant: Meets Australian Design Rule 6/00 Category 2a for rear indicator lamps on heavy vehicles, confirming the 2146-H24 is road-legal as a rear indicator function module on trucks and trailers operating on Australian public roads.

6W Efficient Operation: At just 6W power consumption, the 2146-H24 draws significantly less current than equivalent incandescent indicator modules, reducing the electrical load on trailer circuits and minimising heat generation in the lamp housing.

Multivolt 9–33V Input: Covers the full range of 12V and 24V heavy vehicle electrical systems in a single module without requiring voltage-specific variants, simplifying procurement for mixed fleet and workshop environments.

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

Pre-Wired 200mm Cable: Factory-fitted 200mm cable provides a short, neat wiring connection into the existing lamp housing wiring circuit, suited to the close-proximity wiring arrangement within a combination lamp body.

Surface Mount Fitment: The 195 x 125 x 35mm surface mount footprint is engineered to fit directly into compatible HELLA Jumbo and Designline combination lamp housings for a straightforward drop-in upgrade installation.

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 LED upgrade modules for extended service life.

Technical Specs

Compatible With / Goes Well With

Pairs well with complementary HELLA LED upgrade modules for stop, tail, and reverse functions to complete a full LED conversion of existing Jumbo or Designline combination lamp housings, HELLA Triple Jumbo-S combination lamps including the 2430 and 2431 for full lamp replacement where a complete unit upgrade is preferred, HELLA marker light packs including the 2051BULK, 2053BULK, 2054BULK, 2026BULK, and 2307BULK, and trailer wiring looms and waterproof connectors for professional installation.

Frequently Asked Questions

Which existing HELLA lamp housings is the 2146-H24 compatible with?

The 2146-H24 is designed to upgrade existing HELLA Jumbo and Designline series surface mount combination lamp housings. Confirm compatibility between the 2146-H24 module dimensions of 195 x 125 x 35mm and the specific housing model before purchase. Contact your HELLA supplier or refer to the HELLA compatibility guide to verify the correct module part number for your specific Jumbo or Designline housing variant.

What does UWVO Ultra Wide Visibility Optics mean in practice?

UWVO (Ultra Wide Visibility Optics) is HELLA's optics technology that extends the horizontal visibility angle of the indicator module beyond the standard forward-facing cone of conventional indicator lamps. In practice, this means following drivers, adjacent traffic, and road users approaching from the side can see the indicator activating across a wider horizontal arc, improving the conspicuity of turning and lane-change signals on large trucks and trailers where wide-angle indicator visibility is particularly important for road safety.

What does ADR 6/00 Category 2a compliance mean for this indicator module?

ADR 6/00 Category 2a is the Australian Design Rule governing rear indicator lamp functions on heavy vehicles. Category 2a specifies the required light output, flash rate, colour, and visibility angles for rear indicators on trucks and trailers. Compliance confirms the 2146-H24 meets the legal requirements for use as a rear indicator function in combination lamp housings on heavy vehicles operating on Australian public roads.

Why is the cable on the 2146-H24 only 200mm long?

The 200mm cable length is intentional for this module application. As a drop-in replacement module for an existing combination lamp housing, the 2146-H24 connects directly to the existing wiring already present inside the lamp housing rather than routing a long cable to the trailer loom. The short 200mm pigtail provides sufficient length for the internal connection within the housing while keeping the wiring neat and contained within the lamp body.

Can the 2146-H24 be used on both 12V and 24V trailer systems?

Yes. The 2146-H24 operates across a Multivolt 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 module covers both voltage levels without requiring separate variants, making it suitable for workshop and fleet environments managing mixed 12V and 24V trailer fleets.
