Can I install integrated lights on older Vvolt ebikes?Updated a day ago
Adding Aftermarket Integrated Lights to Your Vvolt
On first-generation middrive Vvolt ebikes, such as the Sirius, Proxima, Centauri, and Centauri S, it is possible to retrofit front and rear lights powered by your main battery. This article outlines the requirements and what to expect if you choose to install lights yourself. This is not possible with first-generation hub-drive ebikes like the Alpha and Alpha S. Sorry!
How it works
Your first-generation Vvolt middrive ebike includes a dedicated lighting lead within the motor harness. Refer to Wire G in the Motor Wiring Schematic (same schematic for all first-generation middrive Vvolts)
Wire G is a five-pin to two-pin connection that terminates with a JST-SM plug. This connection supplies power from the main 36V battery to compatible lights. Many aftermarket lights already use SM-style plugs, though some use Julet or other connector types.
If your bike did not ship with Wire G, contact Vvolt Support and we will send one to you.
Light compatibility
When selecting lights, ensure they are compatible with a 36V electrical system. Many generic e-bike lights are rated for 6–80V, which makes them a safe choice. If a light does not specify its voltage range, do not assume it is compatible.
If you are comfortable with light soldering, you can use any 2-pole 36V light and hardwire it to the system. Otherwise, look for options that include JST-SM plugs for an easier, plug-and-play installation.
Installation and wiring
Installing integrated lighting is considered a DIY modification. You are responsible for sourcing lights, brackets, and any necessary wiring or plugs. Depending on your setup, some cutting, splicing, or soldering may be required.
To access the motor wiring for light installation or routing, refer to our Mid-Motor Swap Tutorial. This process will allow you to route the lighting wires internally through the frame.
Once the lights are installed and connected, you can power them on by long-pressing the “Up” button on the handlebar display.
Important note
Hard-wiring lighting is entirely a DIY project. While we are happy to share guidance and provide the necessary wiring harness, Vvolt does not supply or install aftermarket lighting. Proceed only if you are confident in your ability to safely wire accessories to a 36V electrical system.
Sourcing compatible lights
Below are some sources and product types to help you get started. Vvolt does not officially endorse any brand, but these examples represent the range of available options.
Affordable options
Generic 6–80V e-bike lights on marketplaces like AliExpress, Amazon, or eBay. Look for “JST-SM 2-pin” or “36V e-bike light kit.”
Many of these lights include both front and rear lights with a piggyback connector.
Higher-quality options
Lezyne makes several 36V-compatible front lights, though most require splicing or soldering to adapt to your bike’s wiring.
Busch & Müller (Germany-based) offers durable, high-quality 6–60V lights suitable for e-bikes.
Spanninga offers midrange 6–80V lights with replaceable connectors.
Connectors and wiring
JST-SM connectors are available through Amazon, Digi-Key, or AliExpress.
Pre-crimped plug-and-play harnesses can simplify installation for those who are not comfortable with soldering.
