Blue light is BAD for Rain
You cant see crap!
Silver Stars are a good upgrade from Stock Bulbs
BUT there are better brighter ones out there for around the same price.
And yes the other ones are brighter and better then the Silver stars just they will not give off blueish light
Blue light = Less visible light output
White or Yellowish (to some people) is the best for light output.
Silver stars Can last a LONG time and other times people have had then die in a few months.
Manly people have problems with them in the Fog.Driving light bulbs.
But for the most part, if your looking for easy to find and ok Prices bulbs, Silver stars are ok.
Also yes, the Knight Hawks are very good, Allot of online review sites like them
