There have been an increasingly high number of operators asking about the availability of amber lights for use while on public service events. There are several places that you can obtain them, and they do help folks see you (granted they are not a guarantee against an accident). There are a number of mail order sources and locally. You can mail order them as low as $20.00 from such several online sources. We’ve also seen them for varying prices and quality at local discount and auto parts stores. There is not any one source that is better than the other, just a matter of whether you want to go get it, or wait for UPS. Also this is not an endorsement for any company, just a couple places to start your search.
