Have you thought about changing your yellowish factory fitted angel eye bulbs to xenon white LED bulbs?
Since 2011, BMW has finally replaced those yellowish angel eyes with xenon white LED or HID angel eyes on 3 series E92 LCI, 5 Series F10, New X3 F25 etc.
As a BMW owner myself, I decided to find out if there is any aftermarket kits available for the BMW models before 2011. Luckily, I have found these type of products on the market and decide to stock the whole range in our ebay shop (MylitCo). It has never been so popular. I will list some of the most popular models here in this guide.
First of all, let's talk about price. The cheapest kits cost around £25 to £30. On the other hand, the dearest kits are sold for £100. Even they are the same fitment for the same BMW models, the price are very different. Why? That's all because of the different type of LED chips were used. 3W or 5W high power version LED chips are very commonly used for lower range kits (budget option). The overall light output is less than 5W per bulb. There are some middle range choices, cost between £30 to £50. Such as 2x 5W kits which made by twin 5W LED chips and the overall light output is doubled. The most expensive kits are made by CREE LED chips. (CREE is the market leader and innovator of LED chips, based in US)
Secondly, we should talk about BMW models. Mainly, these LED upgrade kits are direct replacement for your existing angel eye sidelight bulbs. Therefore, you must have had factory fitted yellowish angel eyes to start with. BMW first introduced these halo ring sidelights (known as angel eyes) on 5 series E39 facelift model in 2001. If your bimmer was made before 2001, you have to add CCFL halo rings to get the similar results, there is no direct replacement at the moment.
Finally, I have to talk about OBC errors. Because there are many BMW owners had experienced with dash errors when they change their lights. Unlike any other LED bulbs, all the angel eye upgrade kits have included some sorts of warning cancellors either internally or externally. You don't need to purchase additional resistors.
The whole DIY job takes 20-30 minutes. There are lots of YouTube installation videos are available. You may watch it before changing your own lights.
I hope this guide is helpful. Enjoy your new lights!
