Universal Parts LED Headlight Bulb - BA20D Base

Brighter: 6000K BA20D LED Headlight Upgrade

Transform your nighttime riding experience with the Universal Parts BA20D LED Headlight Bulb. Engineered as a high-efficiency replacement for dim, yellowing halogen bulbs, this "L12 Style" LED projects a crisp, 6000K diamond-white light that significantly improves road visibility and rider conspicuity. With a wide 9-85V compatibility range, it is the perfect plug-and-play upgrade for modern and vintage scooters alike.

Technical Performance Features

• Ultra-Bright 6000K Output: Replaces the muddy yellow hue of stock bulbs with a sharp white beam that cuts through darkness and improves peripheral hazard detection.
• Dual-Beam Functionality: Features a true High/Low beam configuration (10W/10W), ensuring you maintain proper light cutoff and long-range illumination.
• Superior Thermal Management: Designed to run cooler than traditional incandescent bulbs, protecting your plastic headlight lens and reflector housing from heat-related melting or yellowing.
• Energy Efficient Design: Draws significantly less amperage than halogen counterparts, reducing the strain on your scooter's charging system and stator.

Comprehensive Fitment Guide

This bulb uses the BA20D (Bosch) Base, common in many European, Chinese, and Vintage scooters:

Technical Specifications

• Base Type: BA20D (Double Contact)
• Color Temperature: 6000K (Cool White)
• Wattage: 10W Low / 10W High
• Voltage Range: 9V - 85V DC

Mechanic's Note: Before ordering, please check the bottom of your existing bulb. A **BA20D** base features a 20mm diameter base with two contact points on the bottom and two offset locking lugs on the side. Pro Tip: LEDs are polarity sensitive and work best on DC electrical systems. If your headlight flickers at idle, your scooter may be using an AC lighting circuit; we recommend a DC Power Conversion for the most stable LED performance.
