Description

Introduction

Better visibility on the road starts with a stronger headlight bulb, and the GRANT H4 Halogen Bulb 12V 100W is designed to deliver just that. Packaged in GRANT’s distinctive purple retail box marked “+30% More Light,” this H4 lamp is built for drivers who want a noticeable brightness upgrade over standard headlight bulbs, without moving to a full LED or HID conversion. It’s a practical choice for anyone in Pakistan looking to improve night-time visibility on cars using the widely fitted H4 headlight format.

Features

The bulb uses the standard H4 three-pin P43T base, the same globally recognized fitting found across the H4 family, which allows it to slot directly into most compatible headlight housings without rewiring. GRANT’s packaging highlights a “+30% More Light” performance claim along with a 13A current rating at 100W, suggesting a higher-output filament design compared to standard bulbs. As with other halogen headlight bulbs, the glass capsule is designed to handle the heat generated by the higher-wattage filament during use.

Benefits

The core benefit for drivers is a brighter beam that can improve visibility during night driving, on unlit roads, and in Pakistan’s foggy winter conditions. Because H4 is such a common headlight fitment, this GRANT bulb suits a wide range of vehicles that use the standard H4/P43T socket, making it a convenient option for both individual car owners and workshops. Its plug-and-play base also means installation is generally straightforward without needing a mechanic.

Specifications Table

Compatibility

This is a universal H4 fitment bulb, suitable for any vehicle headlight housing built around a standard H4/P43T base — a format used widely across sedans, hatchbacks, SUVs, and vans in Pakistan. As this bulb carries a higher current rating (13A) than some standard H4 bulbs, it’s worth confirming your vehicle’s wiring and headlight fuse can safely handle the extra draw before installation. Always confirm your existing bulb is marked “H4” before ordering, since other headlight types (H1, H7, H11, etc.) use different bases and are not interchangeable.

Installation Guide

1. Switch off the engine and headlights, and let the old bulb cool fully before handling it.
2. Open the rear access panel/dust cover behind the headlight housing.
3. Disconnect the wiring plug and unclip the retaining ring or spring clip holding the old H4 bulb in place.
4. Insert the new GRANT H4 bulb, matching the base tabs to the housing slots, and avoid touching the glass with bare fingers.
5. Secure the retaining clip, reconnect the wiring plug, refit the dust cover, and test the headlights before closing up.

Package Includes

• 1 x GRANT H4 Halogen Bulb, 12V 100W
• Original GRANT retail box

Care Instructions

Handle the bulb by its base rather than the glass, since skin oils can create hot spots that shorten bulb life; if the glass is touched, wipe it clean with isopropyl alcohol before fitting. Store in a dry place and make sure the headlight housing seal is properly closed after installation to keep moisture out.
