We work upstream of purchasing, so the first item delivered to a fleet is a specification document, not a box of parts. Four service motions repeat across every program.
Pencil beam, spread, Euro-beam, combo — we map the geometry of the mounting surface, the working distance, and the driver's sight line before we hand over a model number. Most misorders we see trace to this step being skipped.
Whether the auxiliary lights trigger off high-beam, off a dedicated cab switch, or off a KL7000 controller decides the harness kit. We specify the relay, fuse rating, and wire gauge so the upfitter is not guessing in the bay.
ECE R7/R10/R65/R87 or SAE J-series approval numbers, declaration-of-conformity documents, and the photometric PDF — delivered as one compiled pack for the registrar or insurance auditor.
Vehicles live 10 to 12 years in fleet service. We flag which spare parts stay active, which are being superseded, and what the drop-in replacement looks like so the parts shelf does not stockpile obsoleted SKUs.
We inventory vehicle platforms by year and voltage. 12 V and 24 V systems, CAN-bus generations, and existing sealed-beam vs. H4 vs. LED housing counts are captured on a single spreadsheet.
The shortlist of luminaires is tested against IES files for the target beam pattern. Results go back with notes on glare risk for ECE-regulated roads or SAE-regulated North American highways.
Final part numbers, harness kits, controller modules, and torque specs are compiled into a fleet upfit document. The fleet's internal shop, or our nominated upfitter partner, executes against it.
ECE or DOT declaration files are handed over. On multi-country operators we deliver region-specific packs so each jurisdiction sees the correct approval number.
Lens replacement, driver modules, and wiring harness stock are reviewed quarterly. When a SKU is superseded we pre-quote the successor so maintenance budgets do not get surprised at the counter.
If a luminaire fails in field service we request the failed unit back, document the failure mode, and close the loop with engineering. Fleet operators see the root-cause note, not just a replacement shipment.
Bring the vehicle list, the regulatory target, and the upfit window. We come back with photometric recommendations, harness kits, and a homologation pack the fleet administrator can file directly.
