1. Check the Voltage Range
Trucks and trailers usually run 12V or 24V systems. Choose lamps with a wide 9-30V (or 9-80V) input so they survive voltage spikes and work on both systems.
2. Lumens Are Not Everything
A 12,000 lm lamp is useless with a bad beam pattern. Look for a clear cutoff line and a mix of spot and flood optics. For road use, DOT or ECE compliance matters more than raw brightness.
3. Waterproof Rating
Outdoor lamps should be at least IP67; IP68 means the lamp is fully sealed and can even work submerged. Trucks wash, rain and wade — never compromise here.
4. Housing & Heat Dissipation
Die-cast aluminum housings with fins keep LED junction temperatures low, which directly doubles the lamp lifespan compared to plastic housings.
5. Warranty & Certification
Buy from a factory that offers CE / RoHS as standard, DOT or ECE for road-legal products, and at least a 1-year warranty.
