The Riglow™ C18 LED CANBUS Decoder is an inline accessory designed to help address bulb-monitoring warnings and flickering after an LED headlight upgrade. Supplied as a pair, it connects between the matching vehicle harness and LED bulb.

Connector compatibility

Designed for H4 / HB2 / 9003 connections. Confirm the connector, vehicle monitoring system and LED setup before ordering. Connector fit alone does not guarantee that the decoder will resolve every warning, flickering issue or electrical fault.

Installation

Use the matching harness connections and follow the vehicle and component instructions. Professional installation is recommended. Secure the modules away from heat-sensitive wiring, plastics and other components, and test lighting operation after installation.

Package contents

Two Riglow™ C18 LED CANBUS decoder modules. This product is an accessory, not a light-emitting bulb.

Notes

Supplied as a pair containing two C18 decoder modules. This is an accessory, not a light-emitting bulb. Designed to help address LED warnings and flickering; results are not guaranteed for every vehicle or fault. Earlier listing claimed 9–16V DC input, EMI/RFI suppression, heat-resistant housing and unit-by-unit quality testing. These claims require supplier evidence and are not verified specifications. Material, dimensions, operating limits, internal circuitry and OEM part numbers remain unspecified pending confirmation. Refer to the linked warranty for coverage.
