The best bulbs to replace the d2s are osram cool blue intense! They are not those stupid blue ones that melons use in retro fit hid kits, but they are slightly whiter than stock. They are 5000k opposed to 4300k. They are amazing!!!! Especially if you change the T10 sidelight bulbs to osram LEDs. They match perfectly. Now I changed my reverse light in 2010 for a led bulb, it's bright, but only 7.5w. I've just done some research for you and discovered that you can now buy 50w even 60w led bulbs. Go on eBay and type in the search bar... Cree t20 led 60w. Think you might blind people, come to think of it I'm gonna bite the bullet and order some. One for the reverse light and one for the fog light. You can change the front xenon d2s yourself, it is so easy, and I know jack about cars. I think I posted a set of instructions on here ages ago.
