This LIGHT will SAVE your LIFE.For the past year and half, I have been work commuting 40 mls pr day, NJ > NYC > NJ. With the exception of really bad weather (below 25f, heavy snow or rain). As you all know really good lights are top of the list to stay alive when riding the shoulder alongside motorists.
Even with lots of reflective material, dual Planet Bike Alias Ultra Bright head-lights and a Blackburn 6 LED tail-light... this single Emergency Strobe (1"D" battery) hands down is the most visible, almost offensive, attention grabbing signal I have ever owned. It is military spec’d and certified. It has lasted over 10 years of commutes, tours, back woods camping, rafting and depending on who needed it that day it serviced and protected 5 different riders at any given time thus far. Optimal placement would be center of your back (on a pack) or at the end of a rack not obscured by any clothing or bags.
You can easily find this light for less than $25 USD at any quality outdoor/camping gear retailer. Considering that you may spend $1-5k on your bike, $2-300.00 on clothing and packs, and $150-400 on head/tail lights… another $25 for this no frills real deal bomb proof retina burner is a must.
Now go ride, and get home safe.
