To give you a quick overview, we’ve summarized the most common problems faced with CNC racing LED indicators in the table below. These issues often arise due to the nature of LED technology or compatibility issues with older electrical systems.

Problem	Cause	Solution
Hyperflashing	Low resistance tricking flasher relay	Use a resistor kit to simulate the load of a traditional bulb
Incompatibility with OEM Electrical Systems	Old systems not designed for LEDs	Add resistance to match the circuit requirements of LEDs
Intermittent Flashing	Faulty wiring or incorrect grounding	Stabilize the circuit with a resistor kit
LEDs Not Lighting Up	Insufficient voltage or improper resistance	Ensure proper voltage delivery using a resistor kit
Overheating of Indicators	Excessive current due to low resistance	Use a resistor kit to regulate current flow and prevent overheating

Hyperflashing: The Common LED Indicator Problem

One of the most frequently encountered issues when switching to CNC racing LED indicators is hyperflashing. Hyperflashing occurs when the blink rate of the LED indicators increases dramatically compared to traditional bulbs. This happens because LED lights have much lower resistance, and the flasher relay detects this as a problem, assuming a bulb is malfunctioning.

How Resistor Kits Solve Hyperflashing

The CNC Racing LED Indicator Resistor Kit solves this issue by adding the necessary resistance to the circuit, making the LED setup act like a traditional bulb. The relay is tricked into thinking the load is correct, which ensures that the blink rate returns to normal, avoiding any hyperflashing.

Incompatibility with OEM Electrical Systems

In some cases, CNC racing LED indicators can cause problems when installed on bikes or vehicles with older electrical systems. These systems weren’t designed to handle the lower power requirements of LEDs, leading to problems like flickering, dimming, or even complete failure of the indicators.

How Resistor Kits Solve Compatibility Issues

The CNC Racing LED Indicator Resistor Kit is a perfect solution for this issue. By adding resistance, the resistor kit makes the LED indicators compatible with older electrical systems. This prevents the flickering and ensures that the indicators work properly, just like traditional incandescent lights.

Intermittent Flashing: When the Turn Signal Is Not Activated

Another frustrating problem that can arise is intermittent flashing—where the LED indicators start flashing randomly or when the turn signal switch is not in use. This is typically due to faulty wiring, poor grounding, or issues with the electrical circuit.

How Resistor Kits Fix Intermittent Flashing

The CNC Racing LED Indicator Resistor Kit helps stabilize the electrical circuit by providing the right resistance, which prevents the lights from flashing when they shouldn’t. With this kit, your indicators will only activate when the turn signal is actually in use, reducing distractions and increasing safety.

LED Indicators Not Lighting Up

Sometimes, after installing CNC racing LED indicators, users notice that the LEDs fail to light up altogether. This can be caused by an insufficient power supply, typically due to incorrect or missing resistance in the circuit.

How Resistor Kits Ensure Proper Voltage

The CNC Racing LED Indicator Resistor Kit ensures that the right amount of power is delivered to the LEDs by providing the necessary resistance. This prevents your indicators from staying off and ensures they light up when needed, providing both functionality and reliability.

Overheating of LED Indicators

Overheating is another problem that some CNC racing LED indicators can face. If the circuit has low resistance, excessive current may flow through the LEDs, causing them to overheat and fail prematurely.

How Resistor Kits Prevent Overheating

The RS010B CNC Racing LED Indicator Resistor Kit helps control the flow of current, preventing excessive current from damaging the LEDs. By regulating the electrical load, the resistor kit helps to keep the LEDs cool and functioning optimally for a longer period.
