Hyperflash Note: Fast blinking or bulb error with LED indicators is usually due to the BCM/ECU not accepting LED load, not a fault in the LED. Some cars trigger this instantly, others after the indicator has been ON for 1+ minutes as the LED warms up and current drops slightly. This can be resolved by using an LED flasher relay or load resistors. Such hyperflash or warning behaviour caused by vehicle compatibility or missing resistors/relay is not treated as a product defect and is not eligible for return or warranty claim as per our Return, Warranty and FAQ pages.
