Discussion Overview

The discussion revolves around the customization of motorcycle mirrors to incorporate LED sequential turn signals. Participants explore the technical aspects of building a circuit for this purpose, including the use of components like capacitors, resistors, transistors, and logic circuits. The conversation includes inquiries about the functionality of sequential turn signals and the specifics of circuit design.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant expresses a desire to build LED sequential turn signals for motorcycle mirrors, indicating a preference for hands-on learning and customization.
  • Another participant seeks clarification on the definition of sequential turn signals, suggesting that they involve multiple LEDs lighting up in a sequence to indicate direction.
  • There is a proposal to use transistors, oscillators, counters, and logic circuits to achieve the desired sequencing of the LEDs.
  • A participant shares their preliminary wiring plan, which involves keeping the stock wiring intact while adding circuitry to control three groups of five LEDs each.
  • One participant mentions finding a potential solution through a webpage with various LED projects, indicating ongoing exploration of available resources.

Areas of Agreement / Disagreement

Participants generally agree on the concept of sequential turn signals and the basic approach to building the circuit. However, there is no consensus on the specific details of the circuit design or the components required, and the discussion remains open-ended.

Contextual Notes

Participants have not fully resolved the technical details of the circuit design, and there are references to further research on oscillators and logic circuits. The discussion includes assumptions about the functionality of components and the wiring setup.

I,m trying to do some bike customization and would like to modify my mirrors to have a set of led sequential turn signals on them. You can buy modulators to do this for you but i imagine all it is just a couple cappacitors and resitors pretty much that's involved. I am not a electrical idiot and know quite a bit about how cars and bikes work but when i comes down to stuff like making electrical switches such as this i could use some help. I preffer to build stuff like this on my own since this is one of the ways i best learn how things work, so i definitely want to figure this one out.

What exactly are sequential turn signals? Is that like where there are three in a row or something, and they blink 1-2-3 to show a direction? The simplest way to make it would probably be to use transistors to turn on each LED (or LED group), and make a simple oscillator and counter and logic circuit to do the sequencing.

yeah you have the exact idea. I am still not exactly sure on how to build it though. I am doing some searches do better understad these simple ocillators and logic cicuits also i have the bikes service manual with the wiring diagram which i can post a link to a pic of if neccesary.

So far here's is my wiring plan(of what little there is). I plan as of right now to leave the stock wiring all the sam so that the bike will send the pulse up to the mirror. From there is where i planned on putting in the cicuitry to activated the different light groups. There will be 3 groups of 5 led's.

If you can help me understand how to produce these cicuits it would be appreciated. and i thank you for the advice already given.
