I ran 35W 6000K. No issues at all. LOVE THEM.konigstigerii said:not bad at all, and I presume they are good quality and all? no flickering or issues like that? What wattages is everyone running? I was looking at the 55W ones they had, but read some cars may not have good enough wiring for start up.. I would probably run if I could, 55s for the highs, then the 35 for the rest
