Yes, I've got a vest and triangle as well.My Cannonball kit also includes a couple of reflector vests, a reflective triangle and some road flares. My nightmare is a roadside wheel and tire change at night, danger of getting hit by oncoming traffic.
Looking for flares was what lead me to finding those LED beacons. They essentially act as a flare, but you can magnetically attach them to the vehicle or hang them from something. They are reportedly very bright and can switch between steady and flashing.
I did see that on a couple of lists as well. Thanks for the suggestion!I have had one of these for a few years and it's had about 15 flawless starts up to and including decommissioned military vehicles turned into mobile party platforms in 120+ degree temps and stored in an trailer all year between uses.
