When buying your next bulbs, don’t fall for the scam of counterfeit products. These may claim to be from the Philips brand, though they are poor-quality copies that have not been homologated to ECE-safety standards for legal road use. Thankfully, there’s no need to worry as Philips now uses unique QR codes on the product packaging to help you easily verify the authenticity of your bulbs. Simply scan these using your smartphone and check in minutes. Learn more about counterfeit products.

About Philips

For over 100 years, Philips has been a go-to for high-quality automotive lighting solutions you can trust. Shipping products to over 150 countries worldwide, it’s no wonder they remain a trusted, authority brand lighting the way in every 1 in 3 vehicles.

PLEASE NOTE: The standard unit for colour temperature is Kelvin (K). Brightness is measured in lumen. Standard halogen bulbs produce yellow light at 3200K. Xenon HID technology produces white light at 4200K. The colour temperature for bluish white light is 5000K. The colour and brightness of the headlights in the visual is not an actual representation of Philips headlights. The Philips Diamond Vision range is not road legal in the UK. Philips Diamond Vision car bulbs do not comply with ECE R37 regulations and are not road legal. We are therefore not legally responsible for any future action relating to the use of these non-road legal bulbs if used on public highways or any other on-road situation.

Headlight H1 bulbs


The H1 bulbs gave a nice white light but not a bright beam. Not good in rain or poor visibility.


Reviewed on:

Good white light.


These bulbs are very nice. They produce a nice white light which is very bright. They are fitted to my main beams on my bi-xenon bulbs so I can't really comment on how effective they are on there own but combined with my xenons on full beam they illuminate the road really well. I would recommend.

Philips Diamond Vision


I am satisfied with the Philips Diamond Vision bulbs. I don't need to spend hundreds to convert to HD and have a similar HID effect on the low beam. I was worried about the glaring but it turns out the low beam light is pointing downward enough it does not blind the other drivers.

I use PowerBulbs for all my bulb requirements and have never once been disappointed with either product quality or speed of service.
