Razo is a very popular brand that made in JAPAN (just like PIAA), i have use both the PIAAs and RAZO in the past 9 years, and they all perform very well, they are not those cheap HIDs look bulbs that uses higher watts to produce the bright white like (higher watts than factory specs will burn out the connectors!! beware). The PIAAs and RAZOs use the standard 55W to produce a 110W brightness.
I will not use a cheap bulb on my beloved car. Will u?:wink:
The estimated life time for the bulb is about a year of so if use daily. It also comes with a 2 month warranty if it burns out in that time period.
