This lightbar is the SaberLux-S (
http://www.rontan.com/eng/products/flyer.htm).
Very soon it will be replaced with the new 2011 Wide-E-Tech WingLux (
http://www.youtube.com/watch?v=-NCFnKaaYyI) in full amber.
The WingLux model has the boomerang type curve to it allowing for excellent off-axis viewing.
With the new Wide-E-Tech the WingLux and Maximum lightbars give full 360 degree flash so you no longer have any 'dead spots'.
Of course once received and installed new video will
be uploaded.
I'm also happy to answer any questions you may have in relation to Rontan as, like here in Australia, it isn't the most well known brand even though they have been around for 40 years.
Cheers,
Dugald
