Troubleshooting Checklist overview
Before beginning any troubleshooting, please be sure to review our wiring guide to see an overview of how the system works and confirm that your product is wired correctly. If you are experiencing issues with your multicolor LED lights, please follow these troubleshooting steps:
1. Check the power supply: Make sure that the power supply is functioning properly. If the power supply is not providing enough power, this can cause flickering or dimming of individual colors. Check the power and ground source to the controller to ensure you are getting proper power or ground.
2. Check the connections: Ensure that all connections are secure and properly plugged in. Loose connections can cause flickering or dimming of individual colors.
3. Check for damaged wires: Look for any signs of damage to the wires. Damaged wires can cause the lights to malfunction. Check any inline fuses to see if they are blown (usually found on the red positive of the controller or wiring harness)
3. Ensure the product wired correctly: review our wiring guide. If you have the bluetooth controller please be sure you are using the correct app.
4. Swap outputs on the wiring harness (for example, swap drivers side and passengers side drivers on the identical product) to pinpoint the issue and determine if the problem is the product, driver, or some of the outputs on the controller.
Check the color settings on bluetooth app: Verify that the color settings are set correctly. If the settings are incorrect, this can cause the wrong colors to display, or no color at all. You should not have to change color settings on the app. whatever the default setting are should be correct. Please reach out if you need help finding that setting.
Reset the lights/app : If none of the above steps work, try resetting the lights but cutting power and then re-powering or if using the bluetooth app closing out the app in the background on your phone and turning bluetooth off then back on . If none of these steps resolve your issue, please contact our customer support team for further assistance.
Example product Issues
Device Not showing up in the app: harness may not be getting power, or the controller or regulator may be faulty. (regulator is not used on flow underglow, flow wheel rings, flow interior kits) Check Power and Ground and make sure the harness is getting proper power. If getting power then the issue is the regulator or controller. The determine if the issue is the regulator or controller simply unplug the controller from the regulator while the regulator is getting power and the lights are plugged up to the regulator. The lights should go to white or display a bunch of strange colors. This means that the regulator is good and sending power to the lights, so the issue is the controller.
One halo or DRL not cutting on: This could result from a bad connection or a lousy output of the harness, or a defective product. Swap the outputs to determine the source of the issue.
Both Halos or DRLs are not cutting on: As a rule of thumb if both sides are doing the same thing, this is usually a source issue. This is likely a faulty controller or harness.
Product is Dim: This is likely due to a bad or weak connection or an overloaded controller/harness. (too many products on one controller
LEDs showing when product is off: The product may have lost connection in the middle of a mode or effect or the product may have gotten water damaged. Try unplugging the product for a few hours and plugging it back up. If problems persist, this is usually the signal of a defective product.
The product won't cut off: This could result from water getting in between the connections and triggering them to cut on, or the harness may have a weak ground or positive connection. The controller could have also lost the connection to the harness while the product was on.
Product just showing red or green and nothing else: This is usually the result of either a bad connection or a faulty product. Unplug the product and plug it back in then go through the troubleshooting checklist to determine
Halos or DRL Boards Work but some LEDs are off-color or out completely: Unplug the faulty product and then plug it back in to reset. If the problem persists this is likely the result of a defective product.
Components breakdown :
Remotes & Controllers – RGB Halo Kits
1. Bluetooth Controller
How to Connect in App. (app or controller design may vary based on product)
How to Tell if You Have a Bad Bluetooth Unit
Our new Flow Bluetooth controller 3.0 features full waterproof black housing and can be exposed to water. However, the led connection can still suffer from too much water exposure. Check Power and Ground and make sure the harness is getting proper power. If getting power then the issue is the regulator or controller. To determine if the issue is the regulator or controller simply unplug the controller from the regulator while the regulator is getting power and the lights are plugged up to the regulator. The lights should go to white or display a bunch of strange colors. This means that the regulator is good and sending power to the lights, so the issue is the controller.
Here are Some Other Signs You may have a Bad Bluetooth Unit
- The phone will only connect within a few inches of the controller instead of a wide range.
- You have Checked the red 10amp inline fuse on the regulator and confirmed power is going into the regulator but the device (sp110e) won't pop up in the app.
- The phone won't connect within the app after confirming you have Bluetooth turned on and wiring correct or an error message keeps popping up
- As a rule of thumb, if both sides are doing the same thing, this is usually a source issue, This is likely a faulty controller or regulator.
- If all products hooked up the controller all have the same issue (ie green color not working/ lights get stuck on the color white or, purple, etc color not working ) this is likely also a sign of a faulty source ie Bluetooth controller, or regulator
Here are Some Other Signs that your LED setting needs to be changed within the app
The halos are showing a white + mixed array of colors or showing all colors at once in a strange way. Everything is cutting on but just not showing the correct color. How to fix this: for this please change the led setting to ws2811. If still not working then change led setting to sk6812_rgbw within the app. If this still doesnt work then you likley have a bad bluetooth controller.
How to fix other Bluetooth controller issues
Please submit a request to support and let us know that you have completed the RGB Halo kits troubleshooting guide and that you have determined the issue to be the Bluetooth controller. When reaching out please provide your order number and a picture of the controller.
How to connect
Simply power the regulator and plug the RF receiver into the regulator according to our wiring guide. Please remove any clear or white plastic tabs interested into the bottom of the RF controller (this is to protect the battery from draining while waiting to ship)
How to Tell if You Have a Bad Handheld Controller
After making sure you are getting proper power to the controller and that you have a good positive and ground connection. You should have a nice strong connection with the handheld controller anywhere within 15-30ft of the vehicle. If getting power then issue is regulator or controller. The determine if the issue is the regulator or controller simply unplug the controller from the regulator while the regulator is getting power and the lights are plugged up to the regulator. The lights should go to white or display a bunch of strange colors. This means that the regulator is good and sending power to the lights, so issue is the controller.
Here are some more signs you may have a Bad Handheld Controller
- The controller won't respond to the receiver or LED will not cut on after you have confirmed the battery is good on the remote (when the button is pressed you will see a red light on the remote to signal remote has a good battery)
- If all products hooked up to the controller all have the same issue (ie green color not working/ lights get stuck on the color blue, purple color not working ) this is likely also a sign of a faulty source ie. the controller or regulator.
- lights stay stuck on and won't change colors or move
How to fix
Please reach out to support and let us know that you have completed the RGB Halo kits troubleshooting guide and that you have determined the issue to be the RF Handheld controller. When reaching out, please provide your order number and a picture of the controller.
3. Voltage Regulator or wiring harness (12v to 5v converter)
What is a voltage regulator?
Most flow series/color chasing DRL Boards run off of 5volts instead of 12volts. Due to this, a voltage regulator converts voltage going into the LED's into 5v from 12v, also known as a 12v to 5v converter. If a product includes a voltage regulator is, it's important to power the lights through the voltage regulator and not add power directly into the controller unit itself.
- Make sure you don't have too many LEDs on one controller or one output (flow series products run off 5v with the harness). If too many LEDs are on a single controller/harness, the lights can experience voltage drop (drop-in power resulting in weakened LEDs or product functioning correctly.)
How to tell if you may have a bad Regulator:
- As a rule of thumb, if both sides are doing the same thing, this is usually a source issue. This is likely a faulty controller or regulator. In most cases, the issue is usually the controller over the regulator.
- Color showing dim or weak or red on products (could be bad or overpowered regulator)
- Device Not showing up in the app or no power outputting from the regulator to controller.
- Check Power and Ground and make sure the harness is getting proper power. If getting power then issue is regulator or controller.
- To determine if the issue is the regulator or controller simply unplug the controller from the regulator while the regulator is getting power and the lights are plugged up to the regulator. The lights should go to white or display a bunch of strange colors after unplugging the controller from the regulator. This means that the regulator is good and sending power to the lights, so issue is the controller in this case not the regulator.
How to fix
Please reach out to support and let us know that you have completed the RGB Halo Kits troubleshooting guide and determined the issue to be the regulator. When reaching out, please provide your order number and a picture of the regulator.
4. LED Product
(ex. halo kit or DRL boards, etc.) 
How to tell if you have a bad Led product:
Please factor out the controller and regulator first by following the other troubleshooting guides for these components. Here are some signs you have a faulty LED product.
- Some LED's missing in the halo, strip, or DRL board.
- The LED product won't cut on at all (rare) usually when defective item cuts on but displays missing LEDs or flickering.
- LED product colors not matching or some of the colors on a product not working all of a sudden after working correctly for some time.
How to fix
Please reach out to support for warranty and let us know that you have completed the RGB Halo kits troubleshooting guide and determined the issue to be the LED Unit Itself. Please provide your order number and a picture of the product fault when reaching out.
5. Extension wire or bad connectors 
How to tell if you have a bad connector or extension wire:
- Bad extension: The product flickers when touching or moving the extension wire
- Bad product: Product flickers when touching or moving the product wire
- The product works one minute and then doesn't work the next
How to fix
Please reach out to support for warranty and let us know that you have completed the RGB Halo kits troubleshooting guide and determined the issue to be the product connector or extension wire. Please provide your order number and a picture of the extension wire when reaching out.
Or
Bypass the connectors by cutting off each of the two JST connectors (male and female) and manually splice wires together using the color-coded wires (important: always reach out to our tech support first before modifying any products to prevent voiding your warranty.)
