I found these http://www.xtremediesel.com/rigidind...lightbars.aspx You have to click the small images underneath the main display picture to see low profile bars up to 50". Two 40" bars should fit ok and the "Ugg" factor doesn't seem bad. Do the specifications tell anyone if the gain in light will be worthwhile. The height of the bus should give an advantage for pointing these way out front. The 40" light bar is $1,234 on that site above so I guess that is some indicator that they're quality and produce good light.
Who do I PM about the underside lights that has installed them ? I think Gary D's bus picture has them.
