A while ago i bought some Blue xenon bulbs for the Navi. and what a difference they made from stock. 100x brighter and whiter. well about 2 months ago both the foglights went out at the same time. and i know its the bulb because ill take out the power source for it and plug it into my stock bulb and it work. well yesterday my passenger side bulb went out. so i went to Advanced Auto parts where a buddy of mine works and got some "Cool Blue" bulbs by Silvania. yall they look identical to Stock. they suck. i dont know how i went so long on stock bulbs cuz the difference between them and blue Xenon are incredible. youll never know until you drive with em.
