Super Bright Safety Light
Red / Yellow Super Bright flashing LEDs (designed for police dash).
It's very bright and really gets a drivers attention. Drivers will appreciate your effort to be seen and give you room.
It's not heavy - a single battery and LED light weighs LESS than a water bottle.
It's not cheap - but it's less than a trip to the emergency room.
It's legal - Red and Yellow is approved for this use in most states
Do you want one?
The first one we built in 2009 cost about $150 for the parts. Componant prices are up and I switched to a Li-Ion battery. They are very light, small, and last longer than the SLA (sealed lead acid) type I started out using. The Li-Ion battery is also brighter since it provides 14.8 volts insead of 12 volts that the SLA batteries provide. But the Li-Ion batteries are more expensive. Here is the breakdown:
LED flashing strobe $120 to $150 depending on color
Li-Ion battery $35 to $60 depending on size
Li-Ion charger $25
Misc connectors $2

Here is a picture with the original Lead Acid battery. I had to carry this case that included 2 batteries. It weighed about 24 ounces. The Li-Ion battery is 1/4 the weight and one battery lasts just as long.
Here is the Li-Ion battery
The Li-Ion battery is stored in the zippered seatback carrier. It is small, light and lasts all day.
A single 2,200 mah battery is all that is needed for about 7 hours use. It is also BRIGHTER than the 12V SLA batteries. Note: the red and black connectors in the picture don't come with the battery or light, They are "powerpole" connectors I have and use for various applications, you can use them or others to complete the setup.
Note: the batteries are also available in even higher capacities.
2,200 mah will last about 7 hours
2,600 mah will last about 8 hours
4,600 will last even longer (haven't tried one of those but guess about 15 hours)

The light can be seen about 1 mile away in dark, 1/2 mile in daylight
The movie doesn't do it justice, it is really bright even in the day.
