Introduced in 2005, the “Sports tourer” R-class W251 is renowned for its generous space; up to six adults can enjoy a comfortable and luxurious ride. The model remained in production until 2012. But the lighting technology used in this car is more than 20 years old today.
Factory-fitted options included H7/H7 halogen, D2S bi-xenon (D1S on facelift) and D1S adaptive bi-xenon headlights, all manufactured by Hella, and use E55 projectors. These projectors are known to burn.
The halogen version features a 3-inch H7 projector 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.
The bi-xenon setup features a 3.0-inch projector, designed in the late 90s. These projectors are known to lose their reflective layer right to the point where they become black inside, causing dangerously low light output.
Needless to say, buying new or used original headlights for your Mercedes R W251 is not recommended. But there is fortunately no need for that. Whether your car was factory-fitted with H7/H7 halogen, D2S bi-xenon (D1S on facelift) or D1S adaptive bi-xenon headlights, there are upgrade kits that will fit inside your existing headlights.
These complete retrofit kits not only provide you with superior brightness and durability; they are also more affordable than average Mercedes R W251 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.
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 Mercedes R W251 will look awesome with the luxurious bright light of the latest xenon technology.
