Easy
Baja Designs does have a kit, and it is the most popular. As long as you have a brake light, a tail light, horn, and one mirror you are good leagally. BUT.... My XR600R has the Baja Designs kit, and if you dont swap out your stator, or at least set up a battery kit, you may be blowing lightbulds often. My tail light goes out often. This can lead,(and has for me) to being pulled over, and possibly ticketed. Also when hitting the brake the headlight will dim to a glow for a brief second initially. No matter how brief, it is un-nerving to say the least in the twisties. If you spend the money on a dual core stator and go LED tail light you can have plenty of power to run the lights, and additional lighting in he front, which you will need really. Of course this also requires a voltage regulator. It costs a bit, but if this is your escape goat you dont want to skimp on the things that keep you safe and alive. Oh, and remember that the brakelight will only be activated by back brake and not front.
