I have decided to go ahead and purchase some for my 190e. I have noticed a few different brands such as TYC, Hella and Bosch. Are there any noticable differences in these 3 brands?
Also, how much better lighting can I expect with these headlights?

I am working on buying some off a parts car in the U.K. but if anyone has any they are trying to sell let me know.
