These will work but not sure if as good as the kilerglass. Received the led's today and they look the same except the lead that has the voltage regulator is shorter. It does not appear as bright as the killerglass but right now I am comparing the blue one from Amazon to a red one from killerglass. When I get my blue killerglass replacement I will compare as we'll. Also a difference in amperage. The brighter red killerglass is pulling .018 amps and the blue from Amazon is pulling .o48 amps
