The first AUTOMATIC brake lamp.

Stoptix* is the only automatic brake light that requires no modifications to your motorcycle or vehicle because it is the first product to offer a deceleration indicator solution inside the lamp -- self-powered and self-illuminating.
*patent pending

Stoptix uses disruptive technology to displace the incandescent brake light bulb that has been used for over 100 years.  It is time we all started using a smart deceleration indicator lamp. 

Stoptix increases visibility via early deceleration indication and reduces your chances of being rear-ended.  Indicating deceleration one second earlier at 65 mph is 88 feet of additional stopping distance for following vehicles.

What are riders are saying about Stoptix?

Waterloo, AL
September 20, 2014 
We showed the Stoptix automatic brake lamp to riders at the end of the Trail of Tears Ride. We took no longer than 30 seconds introducing and demonstrating Stoptix. These interviews were unscripted and shot in a single take.

Why You Need a Stoptix Lamp

Motorcycles:  If you ride a motorcycle you need this automatic brake lamp so you don't have to remember to squeeze the brake lever when you downshift or rapidly slow down under engine braking.  It also works great for when your bike runs out of fuel, suddenly slowing until you switch over to reserve. 

Builders and Collectors:  If you are a builder, restorer or customizer of bikes or automobiles then you need to protect your investment by installing Stoptix lamps.  The last thing you need is to ruin months or years of work by being rear-ended.   

Cargo and Fleet:  Stoptix lamps are a cost-effective way to reduce your companies exposure, especially when self-insured, by reducing the chance of the fleet vehicle being rear-ended.  Reduce the down time your business suffers while the vehicle is being repaired.  Reduce the liklihood of your cargo being damaged.  

Passengers:  Reduce your chances of being rear-ended and the possibility of your passengers being injured.  Stoptix lamps are a small cost to pay for this level of increased safety.

Frequently Asked Questions


Will it fit my vehicle?

The Stoptix lamp is designed to fit most tail/brake sockets that use an 1154 (U.S.) or 1157 bulb (U.S.) or P21/5W (old designation: P25-2).  We designed the housing to be shallow enough to install without hitting the reflector in your vehicle but still have a large effective area for higher visibility.  

Socket:  The Stoptix lamp requires a horizontal socket, parallel with level ground, for bulbs using a BA15d metal lamp base.  Note that some trailer lights have a socket pointing upward and that our Stoptix light will not work in these few exceptions.  

Rear-loading Bulbs:  Few 1157 light housings have a rear-loading bulb but Stoptix 1157 won't fit due to the one-inch diameter hole through which the bulb must be inserted.  Our 3157 (plastic wedge base) Stoptix lamps are scheduled to be available later in 2015.

Will it work in older vehicles?

Stoptix will work at voltages between 6 VDC and 30 VDC.  It will work in an older vehicle with a 6 Volt system.  Most LED brake lights cannot.

How long does the battery last?

The battery life should last 3 hours between recharges and still have enough energy to illuminate the LED.  Recharging the battery occurs in two seconds automatically every time you apply the brakes.   If your bike or vehicle has a tail/running lamp that is always on, then Stoptix is always fully charged to indicate deceleration.

How does it compare to the incandescent bulb?

Stoptix has many advantages over the the original bulb it replaces: 

  • Stoptix will emit bright red light so it looks great behind clear or smoked light covers (off-white opaque color when off). 
  • Stoptix will last longer than the incandescent, likely to outlast the vehicle itself.  
  • Stoptix turns itself on when it should!

Is it weatherproof?

The Stoptix lamp is highly weather resistant. Electronics are sealed and protected with special coatings and injection molded casings which keep the elements out.

Will the stoptix lamp illuminate the license plate?

The license plate illumination is not shown in the demonstration video but will be included in a later version of the Stoptix lamp.

I live outside of the United States, can I pre-order a Stoptix lamp?

Yes. The Stoptix lamp will ship worldwide with CE certification.  Stoptix is also designed to meet or exceed stop lamp standards.
