Regarding the subject matter of what light to use, I'd say go for the FedSig Firebeam or SVP Hotshot II. Got a local guy who uses the HotShot II and it had been a while since I'd seen on in use, and it did fine during the daytime. Either one you go for, they're common, so that means getting a used one, if funds are tight, will be an easy task. Also, if parts are needed (new dome, magnet, etc), will be easy to find. Maintenance will be easier, too, if that's ever an issue.
Regarding the subject of using a throw light, some folks have to have 360 degree visibility. I remember some folks having elaborate lo-pro setups and just keep a cheap throw light to be compliant. Regardless of if it's your main warning or just giving you that compliance with a law, I'd say do the halogen throw light. If something happens to it, you won't be out as much compared to if it was an LED beacon.
Good luck with whatever you use.
