Listed specifications

Brand
Riglow™
Model
SP668E – rear-light version
Product Type
Bluetooth SPI taillight controller with driver
Installation
Use exact-version supplier wiring and installation instructions; verify voltage, protocol, pinout and load requirements before connecting.
Fitment
For custom rear-light/taillight applications using compatible WS2811 or WS2812B pixel lights. Verify connectors, pinout, component voltage, load and vehicle connections. No vehicle-specific direct-fit application is established.
Notes
Supplier invoice BDJ-2026100101 dated 01/Oct/26 confirms 2-output and 4-output SP668E taillight controllers with driver and red startup animation. This is distinct from the white-DRL headlight version. Merchant confirmed October 15, 2026 that the same supplied electrical, compatibility, control and reset information also applies to this rear-light controller: DC 5V–24V operating range; controller working current 14mA–20mA; control of up to 600 ICs; WS2811 and WS2812B pixel-light support; Bluetooth app and RF remote control. Working current is not an LED load-current rating. The 600-IC figure is not established per output. Match supply voltage to connected lights; the controller input range does not imply voltage conversion. Total/per-output load capacity, independent output control and power-distribution requirements remain unverified. Factory reset: five consecutive controller power cycles, each time energizing for 2 seconds then disconnecting, restores factory settings and removes existing settings. Follow exact supplier/vehicle procedures using the correctly rated controller supply connection. Do not repeatedly disconnect the vehicle battery or handle exposed live conductors. Brake, turn-signal, reverse and white DRL functionality remain unconfirmed for the rear-light version. Exact vehicle wiring, trigger sources, app identity/device requirements, remote inclusion/batteries and other package accessories require confirmation. Do not infer compatibility with other chipsets or RGBW lighting. Waterproof/IP rating, mounting/environmental suitability, material, dimensions and weight remain unverified. No vehicle-specific fitment, OEM numbers or warranty coverage inferred.

App and RF control for your custom rear-light build

The Riglow™ SP668E Bluetooth SPI rear-light controller with driver features red startup animation for compatible custom taillight projects. Choose the 2-output or 4-output version. This is distinct from the white-DRL headlight module.

Compatible pixel lighting

Supports WS2811 and WS2812B pixel lights, based on the product information confirmed by Riglow. Match the controller, lighting protocol, connectors and pinout before installation.

Electrical requirements

The confirmed supplied specifications list a DC 5V–24V operating range, 14mA–20mA controller working current and control of up to 600 ICs. The working-current figure is not an LED load-current rating, and the 600-IC figure is not a confirmed per-output allowance. Use a supply voltage matching the connected lights; the controller input range does not mean a 5V strip can accept 24V. Total and per-output load capacity and power-distribution requirements still need exact-version confirmation.

Factory reset

The supplied reset procedure specifies five consecutive controller power cycles: energize for 2 seconds, then disconnect power, repeating five times to restore factory settings. This removes existing settings. Perform this only through the controller’s correctly rated supply connection, following supplier and vehicle procedures. Do not repeatedly disconnect the vehicle battery or handle exposed live conductors.

Installation and functions

Bluetooth app and RF remote control are confirmed. Obtain the exact rear-light-version wiring diagram before connecting vehicle circuits. Brake, turn-signal, reverse and white DRL functions are not established by these specifications. Output count alone does not establish independent output control. Package accessories, remote inclusion and batteries, waterproofing and vehicle-specific fitment require confirmation.

Guides and FAQs

SP668E Rear-Light Controller – Setup Checks and Factory Reset

Step-by-step instructions

1. Identify the SP668E rear-light version and selected 2-output or 4-output module. This version has red startup animation; do not substitute the headlight module's white DRL wiring.
2. Obtain the exact rear-light-version supplier wiring diagram, protection, mounting and commissioning instructions before connecting vehicle circuits. Do not infer wire functions from colours or a generic strip diagram.
3. Confirm compatible WS2811 or WS2812B pixel lights, connectors and pinout. Match the supply voltage to the connected lights within the controller's DC 5V–24V range. The range does not imply voltage conversion.
4. Verify LED load and power-distribution requirements with the supplier. The 14mA–20mA figure is controller working current, not LED load capacity. Up to 600 ICs is the stated maximum control capacity, not a confirmed per-output allowance. Output count does not establish independent control.
5. Follow the supplier's setup instructions for Bluetooth app and RF remote control. App identity, device requirements and exact vehicle triggers still require confirmation.
6. Factory reset only when required: cycle controller power five consecutive times, each time energizing for 2 seconds then disconnecting power. This restores factory settings and removes existing settings. Use the correctly rated controller supply connection and exact supplier/vehicle procedures. Never repeatedly disconnect the vehicle battery or handle exposed live conductors.

Notes

Merchant confirmed October 15, 2026 that the supplied DC 5V–24V, 14mA–20mA controller working current, up-to-600-IC capacity, WS2811/WS2812B support, Bluetooth app/RF control and reset procedure also apply to this rear-light module. Supplier invoice confirms controller with driver, 2- or 4-output versions and red startup animation. This guide is a setup checklist and supplied reset procedure, not a complete vehicle wiring diagram. Brake, turn-signal, reverse and white DRL functions remain unconfirmed. Exact pinouts, vehicle trigger connections, fuse values, total/per-output load, waterproof rating and mounting suitability still require verification. Package accessories, remote inclusion/batteries, tools and installation duration are not inferred.
Which SP668E rear-light version should I choose, and is it the same as the headlight controller?
Choose the 2-output or 4-output rear-light controller to suit your verified lighting setup. Both versions are taillight controllers with a driver and red startup animation. They are distinct from the SP668E headlight version; do not assume the headlight module's white DRL feature applies.
Riglow confirms Bluetooth app and RF remote control, WS2811/WS2812B pixel-light support, a DC 5V–24V operating range, 14mA–20mA controller working current and control of up to 600 ICs. Match the supply voltage to the connected lights: the input range does not imply voltage conversion. Controller working current is not LED load capacity, and 600 ICs is not a confirmed per-output allowance.
To restore factory settings, the supplied procedure specifies five consecutive controller power cycles, each time energizing for 2 seconds then disconnecting power. Reset removes existing settings. Use only the correctly rated controller supply connection and exact supplier/vehicle procedures, never repeated vehicle-battery disconnection or exposed live conductors.
Before installation, confirm connectors, pinout, total/per-output load, power distribution and exact vehicle wiring with the supplier. More outputs do not establish independent control. Brake, turn-signal, reverse and white DRL functions, waterproof ratings, app identity/device requirements, and remote inclusion/batteries remain unconfirmed. Obtain the exact rear-light-version instructions rather than guessing connections.
