About the laws, i checked. For Fog lights only yellow is permitted(Size of bulb), Driving Assistant light you can use the standard Yellowish/white, Superwhite or Xenon. For headlights Xenon are legal(For certain bulbs) the watts i believe can not be over 100. And the Wiper Spray lights are not legal in Blue. Also if there are any blinking lights between blue and white are illegal(Change your High beams to Xenon or Superwhite to match the Low beams) I know some cops when they pull over ricers from china town they make sure both are changed because they can give you a ticket for probably cause. Another thing is to make it to attractive. I used Nokya's 9006,9005 For hi and low at 85 watts, and the PIAA Fog lights also 85 watts. and there hasn't been any problems yet and they light the street up better the then any stock 55watt. Another thing is Choice of brand. The shitter the brand the Worse it will attract.
