Philips DiamondVision H4 – Ultimate White Light Headlight Bulbs

Give your vehicle headlights a distinctive, premium white-light appearance with Philips DiamondVision H4 halogen headlight bulbs.

Designed for compatible vehicles using an H4 halogen headlight system, DiamondVision provides a noticeably whiter appearance than conventional yellow-toned halogen lighting. The blue-coated bulb design helps create the crisp white-light effect while retaining the convenience of a conventional halogen replacement.

The H4 dual-filament configuration provides both low-beam and high-beam functions in compatible headlamp assemblies.

Supplied as a twin pack of 2 bulbs, allowing both headlights to be replaced together for a more consistent appearance.

Why Choose Philips DiamondVision?

Premium White Appearance

DiamondVision is designed primarily for customers looking for a crisper, whiter headlight appearance compared with conventional halogen bulbs.

For compatible H4 halogen applications, customers can achieve a whiter appearance without converting the headlight assembly to an aftermarket LED system.

H4 Dual-Beam Design

H4 bulbs contain both high-beam and low-beam filaments, allowing one bulb to perform both functions in compatible headlight assemblies.

Replace Both Sides Together

The twin-pack configuration allows both left and right bulbs to be changed at the same time for a more consistent colour and appearance.

Customer FAQs

What bulb type is this?
This is a Philips DiamondVision H4 automotive headlight bulb.

How many bulbs are included?
The package contains 2 bulbs.

Is DiamondVision LED?
No. DiamondVision H4 is a halogen bulb, not an LED conversion bulb.

Does H4 provide high and low beam?
Yes. H4 is a dual-filament bulb designed to provide both high and low beam in compatible headlamp assemblies.

Is the light white or yellow?
DiamondVision is designed to provide a whiter light appearance than conventional halogen bulbs.

Will it fit my car?
It will fit only if your vehicle specifies H4 for the relevant headlamp. Vehicle make, model and year alone may not always guarantee fitment.

Do I need a ballast or LED driver?
No separate LED driver is required because this is a halogen bulb. Installation must still match the vehicle's original H4 electrical configuration.

Should I change both bulbs at the same time?
Replacing both sides together is recommended for a more consistent light appearance.

Can I use it instead of an H7 bulb?
No. H4 and H7 are different bulb types and are not interchangeable.
