Review on Powerful And Versatile: NanoFlare 3.5" Amber LED Strobe Light With 33 Flash Modes For Emergency And Police Vehicles by Jeffrey Connel

I'm happy with the purchase mainly the cost. The product is bright and functions as described. A few noticeable differences from my Whelen lights, the quad burst isn't as rapid or precise in the on off. It seems a little slower and appears the LED's bleed into the next burst slightly. They are bright but no where near the intensity of my Whelen M4's. Price wise these lights are worth the slight trade off in performance, they are still bright in daylight and in darkness. Where I live rain and dampness is not a factor so I cannot comment on weather proof.Can now comment on rain, they don't holdup in wet rain. Went out on me but after drying out they function again. I removed the lenses and put clear silicon around the edges, put housing back on and wiped excess off.will see if that fixes it. The foam back gaskets are cheap should be silicon or rubber.
