The bulb is legal for road use.The Sylvania Standard Of Quality: With over 100 years in business, Sylvania is the world leader in automotive lighting for Original Equipment Manufacturers (OEMs) and the aftermarket.
u/icarusthewolf is right, I just replaced mine this past spring for my e92 335i (I believe they have the same headlights). the bulb is the D1S. Definitely get them from amazon, they are OEM and same color as original. Do not get them from the dealer, IIRC they charge like $250 a bulb, absolutely ridiculous.
You should definitely just do both at the same time. The other one might be close to being done as well, and plus, the colors probably won't match since the colors change with age.
I didn't think it was terrible to do, pretty easy actually, except I didn't put the liner back on correctly after the first one, so I had to take it off and do it again (just frustrating to undo all screws because it was cold outside).
Don't touch the bulb with your fingers, you want them very clean (no oils, etc.), and make sure you don't accidentally scratch them along the housing as you slide them into place. You probably will want to take a look online for a DIY guide on how to do this. Find a couple and compare them. Reason being is that I found instructions in one guide telling me to incorrectly take off the clip that holds the bulb in place. I was trying and trying to remove this clip as the guide said to but I couldn't get it off, then I realized that the guide was wrong and that you need to unlatch the clip while the guide was essentially telling me to take the clip off. I'm so glad I wasn't successful in actually taking the clip off because it would have been impossible to put back on. Would've been swearing all night trying to get it back on.
I know I didn't explain that well, memory is a little hazy on this.
I had good luck with this bulb. Matched the temperature of what was in the other side pretty well.
$40 is too expensive?
edit: and you can replace it without taking the front and the wheel off...
