HEADLIGHT REVIEWS
EDITOR’S PICKS
Philips Standard halogen replacement bulb is bright and clear, offering better visibility and wider road coverage. It is a better alternative to stock for the improved performance and longer lifespan it offers.
On paper, the difference in brightness between these and stock bulbs is not the biggest. However, our testing shows that Philips halogens produce a noticeably clearer and more vibrant beam of light.
We found visibility (especially close range) to be better with these bulbs installed. Downroad visibility also benefits from a more powerful throw.
Philips bulbs generate a uniform and well-focused beam. That means you won’t have to put up with dark spots in your field of vision. They produce a crisp beam that brings objects on the road to the driver’s attention more quickly, resulting in better reaction time.
If you want to preserve the warm color tone of your current setup, these H9 bulbs have a 3000k color temperature that looks identical to stock. This is also important as it ensures the bulbs will not draw excess power, thus causing electrical issues with your car’s battery.
Longevity is another strong suit of this bulb. Philips claims an estimated 400 hours of continuous lighting, which is plenty for general use. Drivers report that the bulbs perform well under heavy usage and do not flash or fade in intensity.
Pros
- Decently bright
- Better road coverage
- Improved peripheral visibility
- Flicker free
- Plug & play installation
- Longer lasting than stock
- Uniform beam pattern

Hella’s H9 bulb boosts headlight brightness, adds a bit of coolness, lasts longer than stock and goes easy on your wallet.
We were impressed by the brighter light output of these bulbs that is noticeably better than stock. They are more powerful, allowing their beam to stretch further down the road. By outfitting this set with a wider angle of projection Hella improves your visibility, both downroad and peripheral.
As for the beam pattern, it is solid and unbroken. Philips bulbs generate a more focused beam than these bulbs, but the lower price helps justify the tradeoff. That being said, this is still a clear and flicker free beam that eliminates dark spots.
Unlike other aftermarket bulbs, these halogens maintain the same pattern and fitment as stock, meaning they will not blind oncoming traffic or result in an uneven field of vision.
Furthermore, the Hellas have a slightly cooler tone at 3600k. A far cry from pure white, but great for drivers looking to make their halogens stand out with a cooler hue. A unique blue treatment on the top of the bulb adds to the cool tone while also looking stylish.
Longevity of these bulbs is also well rated, being significantly better than stock, though not quite up to the standard of more expensive options.
Pros
- Brighter than stock
- Improved visibility
- More road coverage
- Color tone is cooler
- Blue capped bulbs add style
- Easy to install
- Longer lasting
- No dark spots
- Maintains DOT approved light pattern

Piaa’s H9 offering delivers noticeably better visibility, dramatically improved whiteness, and premium build that aids longevity.
This particular H9 bulb is for drivers who want the best features and don’t mind the premium price. In testing, we were impressed by how bright and intense this halogen bulb got.
Visibility saw a massive improvement with the Xtreme Plus installed in our headlights. More powerful throw allowed for better downroad visibility, while the wider projection brought more of our surroundings into view.
Functional and fashionable, Piaa’s boosted whiteness aids visibility and looks gorgeous on your car’s front end. At 4000k, the color temperature is a lot cooler than any other halogen and makes spotting potential hazards in your path easier.
The beam these bulbs produce is clear and uniform so you don’t have to deal with dark spots. It does not flicker or flash even after extended use.
The lifespan of these halogen bulbs is another plus point. Not only do they last longer than stock bulbs, estimates suggest that they can outlast the vast majority of aftermarket halogen bulbs.
Our testing subjected the bulbs to a tonne of load and we are happy to report that there were no dips in performance. Long term, we will update this article if we run into any problems, but for now, the Piaa Xtreme Plus bulbs earn our praise.
