6. Test Functionality: Reconnect the battery and activate the turn signal lever. Observe the flashing pattern; it should pulse at a consistent rate without stuttering.

Performance Characteristics

The indicator’s performance is defined by several measurable parameters that guarantee reliability on the road:

• Flashing Frequency: 1.5–2 Hz – a standard rate that balances visibility with power consumption.
• Operating Temperature Range: -40 °C to +85 °C – suitable for both cold climates and hot summer conditions.
• Water Resistance: IP65 rating – protects against splashes, rain, and dust ingress.
• Luminous Intensity: 200–250 cd (candela) – ensures the light is bright enough to be seen from a distance of at least 30 m.

Maintenance Tips

To keep the Van Wezel 4025901 Indicator operating optimally, perform routine checks and maintenance:

• Visual Inspection: Periodically examine the housing for cracks or discoloration that could indicate UV damage.
• Bulb Replacement: Replace bulbs at the first sign of dimming to maintain consistent flashing intensity.
