I'm thinking of mounting two whelen L31 led beacons to the top of my truck. Looking for a way to mount them without drilling into the roof of the vehicle, besides magnet mount of course. My current thought is to buy whelen liberty feet with strap kit and have a local welder cut a plate the width of my roof and depth of the beacons. I'm not sure if that would work thou without flexing and wind noise? Any ideas, suggestions, or comments welcomed at this point. Thanks in advance as always, have a safe and happy new year.
