I figure I spent the extra for a pair of PIAA bulbs (H13/9008) this time, as I have tried the Sylvanias Ultra Star (9006/9007) before. They ultra Stars lasted less than a year (without Day-time Running Light), it longevity was way below my expectation. The PIAA Xtreme white bulbs although rated the same 4000K, they seem whiter and crispier, I just hope this pair will last longer than the Ultra Stars. Only time can tell.
