HELLA 2431 Rear Triple Jumbo-S LED Combination Lamp - Stop/Tail/Indicator/Reverse 12V/24V

HELLA 2431 Rear Triple Jumbo-S LED Combination Lamp - Stop/Tail/Indicator/Reverse 12V/24V

Large-format 597mm Triple Jumbo-S LED rear combination lamp delivering stop, tail, indicator, and reverse functions with integrated 24cm² red retro reflectors, IP69K sealed construction, full ADR compliance across four separate standards, and 5-year warranty for trucks, trailers, and heavy commercial vehicles on 12–24V systems.

Product Overview

The HELLA 2431 is a large-format rear combination lamp from HELLA's Jumbo-S series, stepping up from the 2430 to add a reverse lamp function and integrated 24cm² red retro reflectors alongside the stop, tail, and indicator functions. Delivering four fully ADR-compliant rear lighting functions plus reflector compliance across a substantial 597 x 133 x 59mm footprint, the 2431 is the more comprehensive rear lighting solution in the Jumbo-S range, suited to semi-trailers, curtainsider trailers, and heavy commercial vehicle bodies where a single large-format unit covering all primary rear lighting and reflector requirements is preferred. The 2431 carries compliance across four separate Australian Design Rules: ADR 49/00 for stop and tail functions, ADR 6/00 Category 2a for the indicator, ADR 1/00 for the reverse lamp, and ADR 47/00 for the integrated 24cm² red retro reflectors. This multi-ADR compliance makes the 2431 a comprehensive single-unit solution for rear lighting compliance on heavy vehicles without requiring separate reflector fitment. Current draw is clearly specified across all functions: 0.8A stop, 0.08A tail, 0.5A indicator, and 0.4A reverse, providing precise electrical load data for trailer wiring and circuit protection calculations. All LED modules are factory-assembled and pre-wired into the housing, allowing the complete unit to be installed and connected as a single assembly without field wiring of individual modules. The high-impact acrylic lens provides robust resistance against stone strikes and road debris, while the IP69K sealed, shockproof construction withstands water submersion and high-pressure washing. Both horizontal and vertical mounting orientations are supported, and the 497mm centre-to-centre mounting distance suits standard large-format rear panel mounting positions. Universal 12–24V input covers the full range of heavy truck and trailer electrical systems, and HELLA's five-year warranty provides long-term confidence for fleet operators and trailer manufacturers.

Frequently Asked Questions

How does the 2431 differ from the HELLA 2430 Triple Jumbo-S lamp?

Both lamps share the same 597mm Triple Jumbo-S housing, high-impact acrylic lens, shockproof sealed construction, horizontal and vertical mounting, and 12/24V compatibility. The 2431 adds a reverse lamp function and integrated 24cm² red retro reflectors not present on the 2430, and carries a broader ADR compliance set covering four standards versus the 2430's stop/tail and indicator functions. The 2431 is the more comprehensive single-unit solution where reverse lamp and reflector compliance are required from a single fitting.

What ADR standards does the 2431 comply with?

The 2431 carries compliance across four Australian Design Rules: ADR 49/00 covers the stop and tail lamp functions, ADR 6/00 Category 2a covers the indicator, ADR 1/00 covers the reverse lamp, and ADR 47/00 covers the integrated 24cm² red retro reflectors. This multi-ADR compliance confirms the 2431 meets the legal requirements for all four rear lighting and reflector functions on heavy vehicles operating on Australian public roads.

What are the current draw figures for each function and why do they matter?

The 2431 draws 0.8A on the stop function, 0.08A on the tail, 0.5A on the indicator, and 0.4A on the reverse lamp. These specified current draw figures are important for accurately sizing trailer wiring conductors, selecting appropriate fuse or circuit breaker ratings, and calculating total electrical load across the trailer lighting circuit. Precise current data is particularly valuable for trailer builders, auto electricians, and fleet engineers specifying new trailer builds or refurbishments.

What does IP69K mean for this combination lamp?

IP69K certifies protection against high-pressure, high-temperature water jets directed at the lamp from any angle, typically at 80°C and 80–100 bar pressure at close range. This is the most demanding ingress protection standard for water exposure and confirms the 2431 can withstand the high-pressure washdowns commonly used to clean trailer bodies, refrigerated units, and truck rear panels in transport and agricultural operations without compromising sealed integrity or LED performance.

Is the 2431 suitable for retrofitting onto an existing trailer?

Yes. The 2431 is well suited for retrofitting onto existing trailers as an upgrade from older incandescent or smaller combination lamp configurations, provided the rear panel has sufficient space to accommodate the 597 x 133mm footprint and the 497mm centre-to-centre mounting distance can be matched to existing or new fixing positions. The integrated reflectors eliminate the need for separate reflector fitment when upgrading. A qualified auto electrician is recommended for retrofitting combination lamp wiring on heavy vehicles to ensure correct function connections and ADR compliance.
