LEDs don't have to warm up, so they blink on much faster. Likewise
bulbs cool down and fade out, whereas LEDs blink off.

Red LEDs are RED. Incandescent taillight bulbs shine through thin
lenses, and come across as dull orange-red, as can be witnessed when
viewing any car wit an LED center brakelight at night.
