With the upgrade to new Osram Xenarc Classic bulbs, I wanted to replace the W5W/T10 halogen side lights, as they simply look out of place.

After a extensive review of Sergiu Gabor, I opted for the Hella LED Retrofit bulbs. Fitment is 100%, they are canbus friendly (no errors) and they give a nice white uniform light, which is exactly what I was looking for.
