From 7-inch H4 conversions to IP69K LED work lights, Hella builds the luminaires fleet operators keep on vehicles for 8 to 12 years — with ECE documentation, CAN-bus modules, and spare-parts continuity to match.
Each product family below is grouped by how fleet teams actually specify lighting — by beam purpose, duty cycle, and regulatory target. Use it before cross-referencing part numbers.
| Product Family | Best When | Beam Pattern | Controls Path |
|---|---|---|---|
| Auxiliary & Driving Lights | Highway driving beyond factory headlamp reach; long-haul and commercial vehicle fleets. | Pencil, spread, or Euro-beam with cutoff for ECE fit. | Relay harness + high-beam trigger, optional dimming module. |
| Work & Flood Lighting | Operator work areas, loading bays, agricultural machinery, marine decks. | Wide-flood 60° to 110°; close-range with low glare. | Switched ignition feed or dedicated cab switch, CAN optional. |
| Headlamp Systems | H4, 5¾-inch, 7-inch, and 4x6 retrofits for classic or commercial platforms. | ECE asymmetric low-beam, SAE high-beam, or DRL-integrated. | Standard H4/H7 connector or built-in LED driver. |
| Light Bars & Off-Road | Off-road vehicles, mining equipment, forestry and utility trucks. | Combo spot + flood, or segmented programmable. | Ignition relay harness; Black Magic combined power strip. |
| Signal & Warning Lighting | Emergency service vehicles, airport ground support, roadwork convoys. | Rotating or strobe, 360° radial coverage. | KL7000 central controller, flash-pattern programming. |
We take the beam-pattern intent (spot vs flood vs combo), the mounting geometry, and run it against the IES file library so you know what a luminaire actually does on the vehicle, not just what its marketing sheet claims.
Where the driving light needs to trigger off high-beam, where the work light needs an ignition-only feed, whether the strobe bar routes through a KL7000 controller — the conversation happens before the harness design is frozen.
ECE R7, R10, R65, R87, or the corresponding SAE J-series document — whichever your registrar needs. We supply the approval numbers and declaration-of-conformity files that a fleet manager actually has to file.
Every LED driving light above 60 W routes heat through a cast-alloy body rather than riveted sheet metal. On 24 V agricultural platforms, that single decision keeps L70 above 50,000 hours at a 60° C ambient.
A luminaire can pass IP67 for the housing and still fail at the Deutsch DT connector. Hella ships DT- or AMP-sealed tails and we publish the torque spec — pressure-wash survival depends on both sides being IP69K.
Modern vehicle buses flag LED conversions as "bulb out." Hella 8GS decoders, 8855017 xenon control modules, and LED canceller harnesses live in the same catalog as the luminaires themselves, so compatibility is not an afterthought.
Yes. The 7-inch and 5¾-inch LED retrofits ship with H4 plug pigtails; on CAN-bus platforms we pair them with the matching canceller so the dashboard does not report a bulb fault.
The models homologated for road use carry an "E" approval number on the lens and must be wired to switch off when low-beam is engaged (ECE R48). We supply the approval number with every quote so your registrar can cross-reference it.
The Power Beam, Oval 100, and Module 70 ranges are built for implement duty — heavy cast body, overmoulded cable gland, and tested against ISO 16750-3 random vibration profiles rather than just static IP ratings.
Hella maintains part-number continuity and publishes cross-reference tables. For obsoleted analogue driving lights the LED replacement uses the same bolt pattern and lens diameter, so the bracket stock already on the shelf is still usable.
Neither answer is universal. Highway auxiliary beams usually win on efficacy because run-hours dominate cost. Cab-mounted work lights usually win on glare control and tight cutoff — a 140 lm/W fixture that dazzles the operator is the wrong spec even if it beats a 125 lm/W alternative on paper. We call this out in the photometric review before part numbers are fixed.
Integrated packages compress procurement and single-source the warranty. Modular stacks reward long-cycle fleets: a failed controller zone is swappable without touching the lamp, and LED engines can be upgraded mid-life. We keep both paths live in the catalog so the fleet decides on serviceability preference, not on what the vendor pushes.
Send the platform list, voltage (12V or 24V), regulatory target (ECE or SAE), and install window. Our fleet desk will come back with beam recommendations, a harness plan, and the homologation files your registrar needs.
