The Smart Forfour challenged the notion of compactness in supermini cars by presenting an interior built around the concept of a lounge, inspiring Top Gear presenters to spend 24 hours straight in the car. Popular for its trademark Smart styling and practical utility for the city lifestyle, it remained in production 2004-2006. The lighting technology used in these cars is however more than 15 years old today. Â
Â
The factory-fitted section was an H7 halogen headlight made by Bosch/AL, which features an H7 reflector that produces an average light beam even when new. In many cases, its light output has been further compromised as bulb heat and general ageing cause the reflective layer to peel off.  Â
Â
Needless to say, buying new or used original headlights for your Smart ForFour W454 is not recommended. But there is fortunately no need for that. Whether your car was factory-fitted with H7 halogen headlights, there are upgrade kits that will fit inside your existing headlights. Â
Â
These complete retrofit kits not only provide you with superior brightness and durability; they are also more affordable than average Smart ForFour xenon headlights with bulbs and ballasts, and since all components are brand new, they come with a 2-year warranty. Additional benefits over OEM headlights include Canbus-proof designs and effortless halogen-to-xenon conversions. What’s more, the levelling systems will work without any adjustments to the headlight connectors, and you can use any ballasts that you might already own to save further on xenon upgrades. Â
Â
No matter which retrofit upgrade kit you pick, you will improve the light output considerably, making for safer and more enjoyable driving. And, of course, your Smart ForFour will look awesome with the luxurious bright light of the latest xenon technology.Â
