Vectrix VX1 Tail light and break light issues and solutions
Submitted by Mik on Fri, 08/07/2009 - 14:49
To save time, I just copy here what I wrote on Endless Sphere a while ago:
(See: https://www.endless-sphere.com/forums/viewtopic.php?f=10&t=10068&start=0 for details and much extra information!)
There have been quite a few failures of the Vectrix VX-1 rear light and brake light.
Some say this is due to owners putting stronger globes into the front light, some say this explanation makes no sense. (The stock front lamp is a 35W/35W H1 globe, both filaments can be turned on simultaneously whilst riding.)
Apparently a 55W/65W front lamp will break the rear light.
I have my doubts about this explanation, particularly because my first Vectrix arrived with a broken rear light. I was also told that there was some fault found in the rear light itself that causes the failures, but I know no details about it and do not know if it is correct.
What I do know for sure is this:
A 4WD with a careless driver is quite capable of breaking the plastic cover of the rear light whilst nudging you over the line at a stop sign! I tested it myself!
Luckily, it was so gentle that the light (and I!) still works, and that allowed me to get a close look at the innards of it:
Which, in turn, might provide some answers about the failures NOT involving 4WD's!
Pictures instead of a thousand words: (No time to write up much at the moment):
Here is some information I have been asked to post anonymously (slight edits done for anonymity):
Hi mik, I have been reading the voltage forum and feel that there needs to be some sort of realistic responses to some of the questions asked. The problem being that I need to remain anomous at this stage and so are asking if we could work together on this one where I can relay information to you and you can then post it from your secret source so to speak.
The issue with the taillight is a switching transistor that is blowing out. We are still working on this to ascertain wether it is incorrectly rated or more likely a cheap part with little quality. (out of china). I pulled apart several tail lights and found that there seems to be a common fault with the taillights that are failing. As for current draw from the headlight blowing the taillight, “I don’t think so”. That is like saying “that by turning the light on at the front door caused the light at the back door to blow”!!!
Replacing the headlight with HID should not be a problem, the only thing that I could see as an issue is that the ICM could get confused due to the fact that it most likely reads the bulb resistance to check that the bulb is in fact working. With HID’s this would give an incorrect reading, as with a higher wattage bulb hence the flashing lights on the dashboard.
On last point on this issue is that the Vectrix is designed with some pretty fine tolerances and changing things around could cause stress on the wiring and switching transistors that control the circuits. They are not like you normal bikes or cars where the switch controls the current flow, with the Vectrix the switch sends a signal to the ICM and the ICM then switches the circuit. So please be careful and keep this in mind when modifying things.
Welcome to the world of cutting edge electronics, it wont be long before all vehicles will be built like this, its just a case that the Vectrix is leading the way at this point in time. To all the Vectrix owners, you are leading the way to a brand new world, some will fight it most will embrace it, but the change is here to stay.
