I have a 2 sets of Dual Raiders on the pushbumper of my 2009 Tahoe. I have noticed lately that after a good rain or washing I have alot of condensation built up inside two of the lightheads. This is the first time I have had this problem with a Whelen product. I assume that it may be a seal problem and have thought about removing the lenses wiping them out real good with an alcohol based cleaner and trying to reseal them with maybe a thin coating of silicone on the lens seal. I would hate to have to pull them off and send both back, but if it continiues I may. The look of the cloudy lenes just iritates me! :evil: What is everyone elses opinion?
