What color did you get? Some police get real picky about reds or blues since a lot of states restrict those to emergency vehicles.
My husband installs leds on bikes and I can offer up these few tips. trial mount them so they refect off the chrome but keep them away from the heat sources. Getting them too close to exhaust or on the engine can result in the led housing melting. Usually along the frame are some of the best mounting places, Be sure and check them every so often too because the mounting may need a bit of readjusting or additional glue to make sure they stay in place. Though we don't notice it much our bikes do vibrate and this does have an effect on any mount or connection.
