Hey All, my 2006 e60 525i has some dull yellow Angel eyes and I like the white look so I thought I would look up on YouTube and get some new bulbs, all the videos came up with a certain bulb type which is a big round bulb that's silver and black so I ordered some off eBay that matches e60,
so I went to install them and I was surprised to see my bulbs are not of that, any idea what these bulbs are called? As all the Angel eye bulbs on eBay look like the ones I bought
thanks

 

T10 Bulb

 

Am I right, also known as 501?

 

Is it difficult to take it out? One of my sometimes gives error (once of every 3-4 weeks ), but still working. I'd like to replace in the near future. If I'm right your also has 4 pcs about this bulb isn't it?
