Additional Notes

The 921 bulb is the specified rear turn signal fitment for the Polaris RZR 570 EPS Trail across the 2015-2016 model years.
The 921 follows the ANSI standard recognized in the United States and Canada, classifying it as a regionally standardized component rather than a globally universal one.
It is a wedge-type bulb, designated T15, meaning it uses a wedge base rather than a bayonet or screw base for retention in the socket.
The 921 operates at 12 volts and draws 16 watts, placing it in the range typical of incandescent automotive signal lighting.
The T15 wedge base format is shared across numerous vehicle applications, though electrical compatibility depends on matching voltage and wattage ratings to the specific circuit requirements of the RZR 570 EPS Trail.
