Vespa Lambretta Universal BGM PRO 4-Plug 6V Voltage Regulator

Key Features:

Consistent voltage: Protects bulbs from overvoltage and increases their lifespan.
Improved lighting: Maximizes light output at all speeds, making night time driving safer.
Simple installation: Easily connects to your existing wiring harness.
Supports LED upgrades: Allows use of modern LED lights for better efficiency.
AC & DC outputs: Provides regulated AC for lights and optional DC for charging batteries or powering accessories (like GPS, water pumps, or meters).
Maximizes generator output: Connects all available light coils in series for even more power.

How it works:

AC to AC: Regulates alternator current for the wiring harness.
Sense function: Keeps voltage constant even if loads change.
DC output: Powers or charges batteries and compatible devices.
Ground: Securely connects to frame or regulator housing.

Installation is straightforward—simply match the AC or DC lines to your system and enjoy a more stable, modernized electrical setup.

Upgrade your classic ride’s electrical system with this compact 6-volt voltage regulator, compatible with all alternators and 6V wiring setups. Many older vehicles rely on basic self-regulating systems, where bulb resistance alone prevents overvoltage—and if one bulb fails, it often causes a chain reaction, burning out others and reducing reliability.

This modern voltage regulator provides a reliable, stable 6V power supply, protecting your bulbs and electrical components. It ensures consistent, optimal light output—even at low engine speeds, when vintage systems typically suffer from dim lighting.
