Technical Specifications

Application & Usage Guide

The H4 bulb is specifically designed for vehicles that use a single headlight unit for both high and low beam functions. Its dual-filament design and P43t three-prong base make it a direct replacement for factory-fitted H4 bulbs in a wide range of vehicles, from classic cars to modern motorcycles and commercial vehicles. Always consult your vehicle's owner manual to confirm H4 compatibility before purchase.

Installation Tips: Always handle halogen bulbs with clean gloves or cloth to avoid skin oils on the glass envelope. Ensure the three-prong connector is properly aligned and the bulb is securely locked into the housing before testing. The dual-filament design means one bulb controls both beam patterns.

• Disconnect the vehicle battery before installation to prevent electrical shorts
• Do not touch the glass envelope with bare hands; use gloves or clean cloth
• Verify H4 fitment in your vehicle's manual before ordering
