ok guys ive searched but didnt come up with to much on these particular lights. right now i run a set of cibie super oscars on my bumper, but plan on adding a couple more lights. i have a few sets of hella 500's, and plan on using those as cornering lights on my rack. now i know all the conserns of running lights on a rack, but im looking at a set of the ipf 900's for 150 bucks. so my question is how is the light output on these light? i know they are a driving light not a fog and thats what i want is distance, but compaired to the 500's or say a daylighter how are they. thanks for the help in advance guys
