Generally, white/yellow for head position lamps, red for tail lamps and amber for side position lamps.

All of these LED warning lights have a common flash frequency of 2-6 per second. LED warning lights are a kind of unusual external LED vehicle lights. For a seek of convenient administration, this light is even forbidden to common users in some countries.
