That's the only reason I want it, the flash is more attention-getting IMHO. The WF501B would be ideal for me if it had fast and slow flash modes coupled with a full power mode. The drop in is a compromise, but I'll give it a shot.

I have the ability to do the soldering for a DIY unit, but I haven't done the research on which driver to use. If anyone has a suggestion on which one would work with this light, I might have to break out the soldering iron.
