Has Anyone Tested the Quick Flash and Slow Flash Modes of These LED Strobe Lights?

I’ve been looking at these pre-wired flashing LEDs for a vehicle rear lighting and side accent project.
The product page mentions both “Quick Flash” and “Slow Flash” modes, but I couldn’t find the exact flash timing details. Has anyone tested them in real use, or can the official team clarify the timing details?https://www.ledlightsworld.com/products/50pcs-pack-5mm-led-pre-wired-light-3v-6v-12v-24v-20cm-f5-straw-hat-round-top-bulbs-light-lamp-for-diy-car-boat-toys-party-lighting-project

Thank you for your inquiry.

This LED is available in both quick flash and slow flash modes.

The quick flash mode operates continuously, while the slow flash mode flashes approximately once every 5 seconds, although the actual interval may vary between 3.5 and 6.5 seconds.

The slow flash effect is generally more suitable for ambient decoration or softer warning applications.

These pre-wired LEDs are widely used for cars, boats, models, and DIY lighting projects.
