bumping an old thread for fresh info.
a lot of the links to products are no longer available. I am curious if anyone has used any of the newer products around. I ordered a set of what was supposed to be the latest and greatest from Phillips from the UK but the wire is running out of the back on them and they don't fit (depth wise) into my Bosch H4 headlights..
