How To Install a BackOFF Brake Light Signal Module

Hello Everybody,

I am new to this board and to riding Chetaks.

I thought I'd share with you how I installed a Signal Dynamics Brake Light Signal Module.

This is a device that makes your brake light more noticeable by causing it to flash when you apply the brakes.

This is a pretty easy install, but I took a lot of photos anyhow.

The full flickr set is here: http://www.flickr.com/photos/smellslike/sets/72157622301628763/

and if at any point you become confused take a look at the Signal Dynamics Instructions here: http://www.signaldynamics.com/products/BLSM/blsminst.asp

Step 1.

You'll need a Signal Dynamics BackOFF Brake Light Signal Module.
I ordered mine direct: http://www.signaldynamics.com/products/BLSM/blsm.asp

Step 2.

You need to remove the bolts that are holding your brake light on. They are directly behind your brake light:

Here is what they look like:

You'll need a 10mm socket to remove them.

Step 3.

With the bolts removed the brake light assembly comes right off.

The blue wire is the brake light switching wire.

Step 4.

So we want to be able to revert back to our normal wiring if for some reason the BackOFF module stops working.
In order to achieve that I used crimp on connectors. You can pick these up at any automotive store.
I think the wire gauge is 16, but you'll want to double check.

Anyhow, here I've created a little wire that connects our Brake Light Switch wire to the red wire on the BackOFF module:

And here we've crimped on a connector to the striped wire of the BackOFF module:

Step 5.

Now we just connect the BackOFF red wire to the blue wire and plug the striped wire into where the blue wire used to go.
Note: I put some electrical tape on the connection between the red wire and brake light wire just to ensure they don't come apart.

Step 6.
Give the inside of the brake light a wipe down with a cloth, just to make sure it is clean.
Now using the supplied double sticky tape, stick the BackOFF module to the inside of the brake light.

Step 7.

Reverse the first 3 steps to reattach the brake light assembly.

Pay attention to the weather seal around your brake light.

You don't want any water seeping in there.

Step 8.

Test it. If all went well, you should have a nice flashing effect while you engage the brakes.

If it doesn't work, make sure you didn't accidentally dislodge a wire when reattaching the brake light.
I had the ground come loose on me the first time.

Here is a video of the BackOFF module doing its thing: http://www.flickr.com/photos/smellslike/3941310583/

Done

I hope you enjoyed this How To and I hope this makes you more visible on the road!

Let me know if you have any questions or feedback!

That's great! I've been thinking about getting one of those, as there are lots of hills here in SF and it's often difficult to pump my brake lights when stopped.

Thanks for putting this up here!

Hey you are welcome!

It really is pretty easy to install.

I can see how it would be especially useful in an extremely hilly place like SF.

Good luck and let me know how it goes!
