I was not entierly comfortable with the rear turn signals being red - they are mandatory amber in this country - for fear of having a hard case in the event of a possible accident. So I put colored bulbs in the backup light bezel a while ago to change the turn signal color. Since this left me without functioning backup lights my friend Robert came up with a creative idea. Three small leds drilled into the bezel on the underside enable a white light for backup .. Problem solved, thank's Robert!
