Vololights VoloMod Underseat Module

When it comes to slowing down, motorcyclists do not always use their brakes. This can cause a potentially dangerous situation for drivers/riders behind you who are watching your lights and not your speed. Vololights solves this problem by detecting deceleration by any means via a 3 axis accelerometer. Whether you are using engine braking, downshifting or simply applying the brakes Vololights senses the change and speed and communicates your rate of deceleration to fellow drivers/riders through variable flashing brake lights, giving a clear indication of the urgency with which you are slowing down. So whether you are downshifting to take a turn or slamming on the brakes to avoid hitting a turtle, Vololights has your back.


  • Under seat or other 'black box' mounting
  • Use stock brake or signal lights, no additional lighting included
  • Independent of license plate sizes
  • Brake lever actuated flashing at stop lights for increased visibility
  • Maintains original aesthetics of your motorcycle

Decent product, excellent customer service I'll start off with the review of the product itself and then go into more detail about how ridiculously awesome the guys at Vololights are. I got the module from Revzilla, as always, extremely fast. We to splice into my wiring harness as needed and got everything hooked up in about 20-30 minutes since I took my sweet time making sure everything was right. Turned it on and the module was not working as described on the install instructions. After double checking my wiring, I sent an email to Vololights and within an hour, yes AN HOUR, I was on the phone and FaceTime with one of the CEOs from the company trying to diagnose what was wrong. Turns out I had a defective module so they sent me a new one and had it delivered within like 3 days. At this point, this is by far the best customer service I've ever had. The guy was literally walking me through the install, step by step, and double checking everything for me. The second module worked perfectly, save for the brake light flashing when the lever is pushed in when completely stopped, but that is something to do with the amount of volts coming out of my harness, not the module. Other than that, it works perfectly, lights flash when I downshift coming into a turn and when I break hard due to the accelerometer. The CEO is even working on a modification for my bike that will allow the module to work as fully intended (which to me isn't a big deal because I bought this to make my lights flash when I close my throttle or downshift, which it does). Overall, it's a great idea with an amazing backup in Vololights, but there's always room for improvement. April 21, 2015
Works well Works very well, I ride an SV650 which engine brakes pretty heavily. I did the full mod which includes the turn signals. At a full stop it flashes the turn signals like hazards with the brake lever pulled. With a turn signal on it works like it did before installing it when at a stop. While riding it flashes the running brighter and turn signals when engine braking or downshifting. Slow for a slow braking and very fast for heavy braking. When using the brake lever the brake light pulsates and the turn signals flash. When braking with a turn signal on it works the same but the turn signal is brighter. All in all very effective. A side note: the online instructions that you have to use are a little confusing. "Switch 12v" and "brake Signal" are two different wires, "running lights" and "brake switch" would have been a lot easier to understand. Thankfully it comes with Posi-tap connectors so you can switch it easily. Also listed the #7 wire instead of the #1 which became clear when installing it. February 20, 2015

Robert H: Hi; the unit is 3&7/8 x 2&5/16 x 3/8"
I have a Aprilia Dorsoduro and it has a CANbuss Electrical system so I will be isolating it from the bikes electrical system. I am in Florida for two more weeks and the bike is in Canada so it will be a month before I have it installed but I don't anticipate any problems. You may want to check if yours is CANbuss and act appropriately. Faisal at Volo is most helpful. Robert
