Royal Enfield Wiring Adapter for Aftermarket Tail Lights – GT 650, Interceptor 650, Bear 650 & Hunter 350

When installing an aftermarket tail light, license plate light or rear turn signals on a Royal Enfield, the main problem is usually the wiring. Cutting the original harness can make the installation harder to reverse and can affect warranty coverage in many cases.

The Bonvent rear wiring adapter solves this by connecting directly to the original rear lighting plug of the motorcycle. It creates clean outputs for one tail light / brake light, one license plate light or auxiliary rear light, and two rear turn signals.

The function of this adapter is simple: it lets you connect aftermarket rear lighting to the original Royal Enfield wiring circuit without cutting, splicing or modifying the factory harness.

It is made for Royal Enfield Hunter 350, Interceptor 650, Continental GT 650, Bear 650, Himalayan, Super Meteor 650 and Meteor custom builds. It is useful when installing a tail tidy, a smaller rear light, a license plate light or aftermarket rear indicators.

The adapter uses Bullet Type 3.5 mm female connectors for the aftermarket lighting outputs. This connector type is commonly used on many motorcycle LED tail lights, brake lights, license plate lights and turn signals.

You can use it to connect one aftermarket tail light / brake light, one license plate light or auxiliary rear light, and two rear indicators to the motorcycle’s original rear lighting circuit.

Many riders search for a Royal Enfield wiring diagram before changing the rear light, brake light or indicators. This adapter makes that installation easier because the rear lighting functions are already separated into clear outputs.

Instead of identifying and cutting wires on the motorcycle, the adapter gives a cleaner connection point for custom rear lights and turn signals. It is especially useful for rear-end conversions on Hunter 350, Interceptor 650, Continental GT 650, Bear 650, Himalayan, Super Meteor 650 and Meteor builds.

If you install LED indicators and the flash rate is too fast, you may need motorcycle LED indicator resistors to correct the blinking speed.

This rear wiring adapter is made for riders who want a cleaner custom rear-end setup without damaging the original electrical harness. It is useful for café racer, scrambler, bobber, tracker and custom Royal Enfield builds.

By keeping the original wiring untouched, the installation stays cleaner and the motorcycle can be returned more easily to its original rear lighting setup if needed.

The adapter connects to the original rear lighting plug. The aftermarket rear light, brake light, license plate light and indicators must then be connected to the Bullet Type 3.5 mm female outputs according to their function.

If LED indicators flash too fast after installation, LED resistors may be required depending on the indicators used and the motorcycle configuration.
