R3 R6 R7 R23 and R38 Cover Core Rear Lamp Functions
ECE R3 governs stop lamp intensity and visibility. ECE R6 sets requirements for direction indicators, including flash rate and visibility. ECE R7 covers rear fog lamps and their integration with other functions. ECE R23 applies to rear position lamps and their brightness. ECE R38 defines the performance of progressive turn indicators, ensuring smooth and visible signal transitions. Each regulation ensures that rear lamps perform reliably under real-world conditions. Compliance with all five is mandatory for vehicles and trailers sold in ECE member countries. Failure to meet any one standard can result in rejection during homologation or inspection.
Combination Lamps Reduce Complexity in Trailer Design
Trailer builders face challenges when integrating multiple individual lamps to meet ECE R3 R6 R7 R23 R38. Each separate lamp requires its own mounting, wiring, and certification. A combination lamp like the KOT33 series consolidates stop, tail, turn, and progressive indicator functions into one unit. This reduces the number of components, simplifies wiring, and lowers the risk of non-compliance. It also reduces weight and installation time. For OEMs and upfitters, using a single compliant lamp instead of five separate ones streamlines production and certification. The KOT21 series and KOT15 series also offer multi-function designs with full regulatory coverage.
Voltage Range and Warranty Support Reliable Operation
The KOT15 series, KOT21 series, and KOT33 series operate on 10-30V, making them compatible with standard vehicle electrical systems. This range covers most commercial and utility vehicles, including trailers and forklifts. The 2-year warranty applies to all models and covers defects in materials and workmanship. This warranty is confirmed on request and applies to all units supplied. The consistent voltage range and long warranty reduce risk for buyers. It ensures that the lamps will perform reliably over the expected service life of the vehicle or trailer.
