Prices shown in currencies other than USA Dollars are estimates based on current exchange rates. We will charge your credit card in USA Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.
Shipments outside the USA are declared as “bike parts” for customs purposes and will include the actual amount paid for merchandise and shipping. Jenson USA will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.
If you're tired of guessing how much battery life you have in your lights, the Thunder Blast fixes that with Serfas' blast audible warning system. The Serfas Thunder Blast Taillight gives you style and safety in one high- powered and affordable package. Capable of alerting you with a loud 85 decibel signal, the Thunder Blast let's you know when 10 minutes of battery life remains. This allows you to know when to turn down the power on your light to extend the run time to get you safely home. The beeping continues once per minute until the last minute of run time. This USB rechargeable light comes with 40 lumens of firepower while giving riders’ several different rear facing mounting options with its' extra long straps. The Thunder Blast makes you visible up to 1 mile away, which will help keep you safe in the concrete jungle.

Comments about Serfas Thunder Blast Tail Light:
I use it on every ride, day or night, It increases my visibility to drivers even during the daylight hours. I use it on the high intensity/blinking setting and it lasts for all of my rides. I have yet to hear the audible warning when the battery is down to 10 minutes since most of my rides are less than 4 hours, but this is nice to have since my previous light would die and I wouldn't know about it unless I got off the bike. Worth every penny!
