| Hello,
Also posted on the VOG.
Just for giggles I built some LED tail lights for my Vision, quite pleased with them. Here's a comparison of the stock and custom lights.

Northeast Ohio | I assume when you brake and the turn signal is on, the opposite side lights up like it did when you braked earlier?

| Hello,
Yes, if you brake and turn, the non-turn side flashes and lights just like the brake by itself and the turn side does the turn pattern.
It was a great experience for me because I was able to do a few things I've wanted to do for a while - learn how to design high-current switching power supplies, learn how to program a particular line of microcontroller, and learn how to program pulse-width-modulation.

| Hello,
Yes, the cruise control still works. There were a number of electrical oddities I finally figured out, Victory does some weird stuff on a couple of the lamps like lifting the ground instead of lifting the supply voltage (not normal!). I ended up with two termination resistors per side - one low wattage to terminate one of the lamps that "floats" when it's not on, confusing the logic, and another high wattage to reduce the turn flash to it's normal rate since the front is still incandescent (which eventually will be changed).
As far as price, this set is the prototype and as a result has more wiring harness labor and a more expensive power supply than is economical for an affordable unit. Example, the power supply / computer board is mounted on the back of one of the LED boards with wiring connecting everything. Feasible but not economical. I'm going to work out doing everything on a single board per side to reduce cost and see what parts and labor will be, at that point I'll post about it again with more info and some pricing.
I have a question for those that care to comment - to get the look requires cutting the rear off the buyer's lamp enclosure. It looks the same from the outside. Does anyone care about that kind of abuse?
Thanks for the positive comments.
Hugh

Allen Park, MI | I would think that as long as we can keep the lenses watertight that it wouldn't matter?...just my opinion. |

| Hello,
Monkeyman on the VOG forum made a valid point about this topic - since my cruise control still works and my flash rate is normal, how about posting the electrical information I gained so others can benefit. Hopefully this will help those working with their own LED Vision solutions.
-------
Good point about the resistor tribal knowledge. To help others here's some information I gleaned through the process -
Each side has three 3157 lamps, each with a dim and a bright filament. Starting from the top I've been referring to them as 1A=dim, 1B=bright, 2A=dim, etc.
Lamp 1B is the flasher and it's a 27W filament. Doing the math, it needs a 6R/50W resistor to reduce the flash rate to normal. Since the fronts have not been changed from incandescent yet I wanted the flash rate to be normal. If you use a higher value resistor to consume less power you'll only reduce the flash rate partially, I decided to use the full 6R.
Lamp 3B (one of the brake lamps) has an odd characteristic, it floats to a non-zero voltage when it's on but it's a high-impedance source. Therefore putting a 470R/1W resistor across it reduced the float voltage to a couple of tenths of a volt with little power consumption, fine for the logic inputs I'm using.
Hope this helps,
Hugh

Madison/Huntsville, AL | Extraordinary work Hugh. I'm rarely a fan of anybody's custom lighting. Still happily running the stock lights on my 8 y/o Vegas that I've modded many other ways. Having said that, I'm a huge fan of what you've done here. Bravo. If I change anything, I'd suggest making the blinker 'motion' a little faster. Make the speed better replicate a stock blinker rate. To me it could be mistaken for a novel lighting trick before it's recognized as a 'blinker'. jmho .... I have a question for those that care to comment - to get the look requires cutting the rear off the buyer's lamp enclosure. It looks the same from the outside. Does anyone care about that kind of abuse? .... As mentioned above, it boils down to protection from the elements. If that's not a problem, I wouldn't be opposed to some cutting on the backside. Or, just duct tape it when your done.  |
