Street legal kits are available from many sources. I purchased mine from an outfit in Arizona called EZ LED. Here is their website. [http://www.EZTSK.com]
You have to develop your own plan for installing your parts. My Outlander has bumpers front and rear. There is no adequate exposed plastic front or rear to mount the LED turn signals. I removed both bumpers and discovered plastic corner pieces had enough room under them to mount the LEDs. Good news. I routed the "red" right and "green" left turn signal cables inside the bumper pipes. I will have a little "jump" between the bumpers and the plastic body work on my Can Am, but the jump is well protected.
I'm using a "right" and "left" cable (2 of them) instead of cutting into one cable. Wire is cheap and it reduces the chance of error. I will take these two and join them into one cable that I will run under the bodywork of the Outlander to the handlebar area where the toggles and indicator lights will be mounted. It is important to me to label each cable to insure there is no confusion later about which is right "red" and left "green" cables and wires within the cables. The white wire is ground.
The next job was running the turn signal cables under the Outlander. I elected to follow the existing wiring harness where I could. I ran cables from the front and rear bumpers to the "console" area. I used wire loom under the front and rear body pieces.
Now to figure out the console layout to mount the toggle switches and indicator lights and horn button. The Outlander had a "bump out" in the removable center console plastic that had just enough room for the right and left toggle switches and the indicator lights and the horn button. It is tight, especially considering I had two cables, one from the front and one from the rear bumper, and two indicator lights, a ground wire, and a horn push button with two wires.
My golly I tested the turn signals and they worked! I passed the final exam! I am pleased with how bright the turn signal LEDs are.
Now onto the horn. I placed the push button on top of the dash, red button. It's like a bell ringer in an old hotel. I pulled a wire from the battery positive post to the dash switch, and from the switch to the horn. I located the horn under the right front side, just behind the shock mount and radiator. I used an L bracket bolted to an upper frame cross member. I insured I had a good ground connection through the paint. Here is a photo of the location. The horn is good and loud.
My Outlander came with a license plate bracket above the hitch receiver. So I just used the license plate light and wires supplied in the kit. I did not need the plastic bracket. I found the 12v and ground wires from the tail lights, and spliced into them to power the license plate light. This was straightforward. The light is nice a bright.
Okay, the job is done and my Outlander has the necessary "street legal" equipment similar to a motorcycle. I had already installed Can Am rear view mirrors, which I find handy even while trail riding. My machine is no racer, just a cruiser.
