At a development cost of nearly US$1 billion, the BMW 8 E31 was originally unveiled at the Frankfurt Motor Show in 1989, introducing an entirely new class of BMW. It presented a significant step up from its predecessors, featuring much stronger performance and a sleek, aerodynamic design that pushed the drag coefficient right down to 0.29. Having remained in production until 1999, the lighting technology used in this car is however 30 years old today.
The factory-fitted headlight was a halogen headlight with an H1 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.
Needless to say, buying new or used original headlights for your BMW 8 E31 is not recommended. But there is fortunately no need for that. Whether your car was factory-fitted with H1 halogen 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 BMW 8 E31 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 BMW 8 E31 will look awesome with the luxurious bright light of the latest xenon technology.
Since the main lens is clipped onto the housing and easily removed, retrofitting these headlights is a very straightforward affair. Only minor modifications are needed to make the new projector fit: https://www.retrofitlab.com/blog/bmw-e31-evox-r-hella/
