Using Arduino to control an existing bicycle light

Hello all!

I am attempting to create a simple brake light for my bicycle so motorists will know when I am slowing down.

My big question: is it possible to "hack" an existing led light like the one found here (http://www.amazon.com/Generation-Blitzu-Cyclops-Rechargeable-Light/dp/B00W7Y27CQ/ref=pd_sim_sbs_468_3?ie=UTF8&refRID=1A4P4203WGXF3W40WMTN)? Can it be controlled using arduino?

My initial idea was to use a force resistance sensor on the brake lever to detect the braking which would then control the taillight.

Thanks!

The light you chose is waterproof so it may be difficult to open. You need access to the switch which controls the light. Also it has several modes. Most often the modes are selected by a simple "press button x times" user interface. This is not ideal for your purpose.
To begin just buy a simple battery-powered taillight (about 3$ i guess) and try to just control on/off for a start
