After a friend had his bike light stolen and got hit by a car, MIT bike geeks built a Theft-Resistant Bike Light.
The Kickstarter campaign is about to end. When it does, you can still pre-order a discounted defender. Go to signup.bikegotham.com

Last summer, our friend got hit by a car...
He was riding his bike home at night after a thief stole his bike light. His story isn't unique. As it turns out, 1 in 3 city bikers have had their lights stolen and 80% of bikers frequently forget their lights at home.
We want to make city cycling safer
so we created The Defender - theft-resistant bike light. It locks onto your handlebars making it next-to-impossible to remove. It's designed by our very talented friend, Ori Levin of Tsor Design.
It's tough as heck and super-bright
The Defender is made of lightweight aluminum, has ultrabright LEDs, and has 3xAA batteries for 100 hours of battery life. We've put it through extensive durability and reliability testing and it's nearly indestructible.
No tool from a hardware store can remove it
you need a security screwdriver which is included in the box (we've upgraded the security screwdriver from what you saw in the video for added security). If you lose it, we'll send you another one. It takes 30 seconds to attach the light. You can't steal the batteries either. You need the tiny allen key (provided) to open up the set screw which releases the battery door.
It's very, very waterproof because
The Defender has three, tightly sealed silicone gaskets. You can leave it on your bike outdoors year-round.
We have all kinds of cool awards, like t-shirts and water bottles.
American Apparel T-Shirts. We'll get the colors and sized from you later. The water bottle is Specialized, BPA-free and anti-bacterial. It's what the pros use.
We made a Limited Edition "Gunmetal Black" Light with serial numbers
So far we paid out of pocket, but
we'll use $13,500 to make the dies for aluminum casting, $2,000 for the silicon gasket compression molding tools, $1,500 for our custom printed circuit boards, and $1000 on exhaustive reliability testing to ensure a long lasting bike light.
Here are some detailed specs
Update: Approx 40-60 Lumens. Still choosing the final LEDs and still testing. Light has steady and 1 blinking mode (4Hz).
We believe our backer, "Allen", answers that best in one of his comments: "There are really only three useful settings for the switch on a bike light: Off, On, & Blink. Please resist the temptation to include three different blink speeds or rhythms. I have bike lights where I have to push the button five times just to turn it them or off."
A security screwdriver which you can't get in a hardware store. You'd need to order it online. So it'll be the toughest thing to steal off of your bike. Bike light theft isn't premeditated, its opportunistic. If someone ever steals your Gotham light, get in touch. We'll help you out.
Let it rain! It's designed to be submerged up to about 1 foot under water, which will certainly make it last through the toughest rain storms.
On your handlebars - either above the bar, or hang it below the bar. Get creative, Brad put one on each of his bar ends.
As you know, city biking can be a battle. We captured the struggle of the urban cyclist in our design.
Highly unlikely. If it does, give us a shout. We'll work something out.Highly unlikely. If it does, give us a shout. We'll work something out.
All standard sizes. From undersized to oversized: 22mm-32mm (7/8 inch to 1.25 inch).
It's a "be seen" light. So it has 30° spread. We also designed it to have a reflection off of the front face of the light. That reflection happens at 80° so it shines along the periphery.
Right now silver (as seen in the photo and video) and Limited Edition Gunmetal Black. We may do more colors in the future, but not in the current production run.
