HA!  I can picture it. 

I'm famous for the posters but proudest of that mod.  It makes such a huge difference at a stoplight.  You're gonna love it.

Nice job guys.  Gives me a warm fuzzy on a cool fall day.

It's ironic that the trunk for the Cross Bikes comes pre-wired with plug-n-play brake lights and turn signals (LED no less!) but the Vision still doesn't.  Kind of pisses me off thay they still haven't upgraded the flagship/starship.  Maybe 2012.

For you new guys, here's the history behind why I did the mod (and am so passionate about it). 

On your stock Vision, when you hit the brakes, the bottom 4 bulbs of the "V" light up.  No prob.  When you are going down the road and you want to change lanes, the top 2 bulbs of the "V" are the turn signals.  No prob.  The problem comes at an intersection.  When you roll up to an intersection, you hit the brakes and the bottom 4 light up.  While you are braking, if you turn your blinker on, the middle 2 bulbs dim (back to running mode) and only the bottom 2 brake lights stay lit.  Victory did this on purpose to create more contrast when the turn signals come on.

Not a big deal until you are at an intersection with a car/truck right on your butt.  Lets say you pull up to an intersection and stop.  You decide to turn right and the car behind you is also going to turn right.  You're looking left and he's looking left for a gap in the traffic.  He is creeping up on you and your bottom 2 lights disappear under his hood.  You turn your blinker on and your middle 2 lights go out at the same time.  It looks like you just came off the brakes.  He looks left again and continues to creep up (thinking you are pulling out) but you haven't moved....crunch.  This has happened to several people here (including VaRyder) and I can see why. 

Another simple mod is to disable the dimming feature of the middle lights when you have the brakes and a turn signal on at the same time.  The middle brake bulbs stay fully lit, screw the contrast.  KansasGuardsman wrote up this simple mod here:  http://www.vision-riders.com/bb/forums/thread-view.asp?tid=2680&posts=1&start=1  and Radioteacher made a great video of it here:  http://www.youtube.com/watch?v=5-QPAMpVmhw  (They are both geniuses, by the way.)

Do what you have to do to get a brake light up on your trunk at eye level with the driver behind you.  You will feel a lot safer when they come barrelling up behind you.

I took it a step further....

I had the Kury 4710 already on my ride, making the trunk lights

perform as brake and turn signals. I took 2, 30 LED strings, and

wired them into the trunk lights, so now I have:

60 leds at eye level + 4 lower & 2 trunk for brake lights,

30 leds at eye level + trunk & top of "V" for signals,

People have said they can see me a mile away... which to mwe is a GREAT Thing...

If they can see me, hopefully they will not hit me!

The Kuryakyn 4710 mod is by far the best way to go but definitely not for someone who is intimidated by wiring stuff.  I tried to make mine as simple as I could so that as many people as possible would at least give it a try.  I could have done it with a lot fewer LEDs but hey, go big or go home. 

Here are a couple of other videos with aux trunk lighting.  All are great ideas.  Just do it!

http://www.youtube.com/watch?v=mmn-J0tooo4&feature=related  This is the Kuryakyn 4710 mod.  Other guys have added red/amber LEDs plus tied it into their stock trunk lights for maximum effect.

Thanks for the updates Adolf and Tony.  Tying the two wires together into that spade is a great idea if you don't plan on removing the trunk.  (It sounds like the LED wire is permanently attached (crimped) to the white/pink wire, right?)  The genius of the PosiTaps is the ability to just unscrew the small cap, pull the wires out and put the caps back on.  It's a one-shot sealed-up pinhole in your wires that is always ready to go either way.  I would not have done this mod with the old style 3M wire taps that shred your insulation and are not weather proof.  If I were BMW anal about it I would put dielectric grease in the large cap surrounding the wire.  But I'm not, so I didn't. 

I have the Muth LED signal mirrors (Thanks again to devilboy for being the prototype Vision on that!) and soldered/shrinkwrapped those connections because I knew they would be permanent.  Having the Muth mirrors is the main reason that I went brake-light only on the trunk.  If I didn't have the Muths, I would have gone Kuryakyn 4710 on the trunk. 

When I'm sitting at a stoplight and have the 99 LEDs and the Muth turn signal all going at the same time, I can feel the jaws dropping in the cars around/behind me.  Cars in the lanes next to me used to pull up even with my dash.  Now they stop a car-length back and just creep up.  It is frickin awesome.
