These 5mm LEDs have a fast flashing IC in them and flash at a nominal 3.0Hz. Maximum supply voltage for these is 5V, they will not flash using, for example, 12V with a resistor.

They are ideal where you need a really attention-grabbing indicator, without the flashing being too fast, like a strobe. Flash rate is around double a normal flashing LED.

Made by Optosupply, part number OSR5MR5A31A-3.0HZ, datasheet is here.
