Multi-Function Vehicle Indicator Light Conversion Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lighting systems, particularly for motorcycles, lack enhanced visibility features, as they primarily rely on single- or dual-function lights that do not effectively convey multiple signals like run, turn, and brake indicators simultaneously, leading to potential overlook by other drivers.
Innovation Solution
The conversion of existing vehicle indicator lights to multi-function run-turn-brake indicator lights is achieved through a run-turn-brake converter circuit and wiring harness, which reconfigures the vehicle's wiring to combine run, brake, and turn signals into multi-level signals, allowing for enhanced visibility by activating bulbs at different intensities based on the signals received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If single- or dual-function lights are used in vehicle indicator systems, then the device complexity is reduced and ease of manufacture is improved, but the visibility and signal differentiation are insufficient
Solution Approach 1:
The patent applies multi-functionality by enabling indicator lights to perform multiple functions simultaneously. The converter circuit allows a single light to display run signals, turn signals, and brake signals by varying intensity levels and patterns. This resolves the contradiction by achieving enhanced visibility through multi-functional lights while avoiding the need for separate dedicated lights for each function, thus not increasing overall system complexity
Solution Approach 2:
The patent utilizes parameter changes by varying the intensity levels of the indicator lights to convey different signals. The converter circuit modifies the electrical parameters (voltage levels) sent to the lights based on the vehicle's operational state, allowing a single light to display multiple functions through intensity modulation rather than requiring multiple separate lights
2Illumination intensity
If dual-filament bulbs are used to provide high and low intensity signals, then the lighting intensity range is improved, but the adaptability to multiple signal functions is limited
Solution Approach 1:
The converter circuit provides universality by taking multiple input signals (run, brake, left turn, right turn) and converting them into appropriate intensity levels for the indicator lights. This allows the dual-filament bulbs to adapt to multiple signal functions dynamically, resolving the limitation of fixed dual-function bulbs by adding intelligent control that enables them to display run, turn, and brake signals as needed
3Adaptability or versatility
If existing vehicle wiring is reconfigured to support multi-function indicators, then the adaptability and visibility are enhanced, but the ease of operation and installation complexity increase
Solution Approach 1:
The converter circuit acts as an intermediary device that interfaces between the existing vehicle wiring system and the indicator lights. It receives standard vehicle signals through a connector and converts them into the appropriate control signals for multi-function operation. This mediator approach enhances adaptability while minimizing installation complexity, as the converter plugs into existing connectors and handles the wiring reconfiguration internally rather than requiring complex manual rewiring

AI summary
Vehicle indicator lights, such as run-brake lights and/or side running lights, are converted to run-turn-brake indicator lights. A run-turn-brake converter is connected to vehicle-supplied run, brake, left turn, and right turn signal leads, the run-turn-brake converter producing left and right run-turn-brake signals. Existing vehicle wiring is reconfigured by disconnecting a first lead wire from the low-intensity input of a first three-terminal brake-run light socket, disconnecting a second lead wire from the low-intensity input terminal of a second three-terminal brake-run light socket, disconnecting a third lead wire from the high-intensity input terminal of the second three-terminal brake-run light socket, and connecting the second lead wire to the high-intensity input terminal of the second three-terminal brake-run light socket. The left and right run-turn-brake signals are connected to the sockets via the second lead wire and via a fourth lead wire, respectively.
