Standard warning lights are great for general use, but specialized missions demand specialized solutions. Whether you need a low-profile light bar for aerodynamic efficiency, a specific amber wavelength for mining, or a unique mounting footprint for marine vessels, off-the-shelf products often fall short. At LIYI, we offer comprehensive OEM/ODM services, guiding you from a rough concept to a fully certified, production-ready warning light.
Every vehicle has unique operational constraints. A light bar that works for a highway patrol car might be too tall for a low-clearance mining truck, or lack the specific flash pattern required by local airport regulations. Customization isn’t just about aesthetics; it’s about integrating safety lighting perfectly into your vehicle’s operational ecosystem without compromising performance.
1. Requirement Definition: We start by understanding your exact photometric, mechanical, and regulatory needs. Our engineers conduct a feasibility analysis to ensure your custom design can actually pass certification.
2. Mold Making & T1 Sample: Once the prototype is approved, our in-house tooling team manufactures precision molds. We then produce T1 samples for your final sign-off before mass production.
3. Homologation Support: Custom shapes can complicate certification. Our compliance team manages the testing and documentation process with certification bodies , ensuring your custom light meets all ECE or SAE standards.
A common misconception is that custom lights cannot be certified. At LIYI, we design with compliance in mind from day one. By understanding the strict photometric requirements of ECE R65 and SAE J845, we ensure that even non-standard housings deliver legally compliant light intensity and distribution.
Q: What is the MOQ for a custom molded light bar?
A: Our standard OEM minimum order quantity is 20 units per production run. For purely custom designs requiring new molds, the MOQ may be higher to offset tooling amortization.
Q: How long does the entire OEM process take?
A: Typically, from initial design approval to T1 sample delivery takes 4–6 weeks. Full certification and mass production readiness usually takes 10–14 weeks, depending on testing schedules.
Before you choose a warning light supplier, ask to see their engineering change management documentation, material traceability records, EMC test data, photometric reports, and modular repair specifications. LIYI provides all of these on request.
