If you need lens anyway, then I would do the ECE , as they did have a slightly better , more defined pattern.. as far as lamps are concerned , Ihave no problem with stock H4s..
Remember, your old lens have road hash , [ wether you see it or not] and new glass will be noticably brighter..

I would also try those +50%s before going with wiring changes [as Troy suggest]
I was thinking of them myself, but for my driving, not needed at all....

The most important factor with lens that do have definate patterns is , of course, proper aiming/alignment..

See archive for article I submitted somewhere in there...
