I'm sure the life of the bulb is a toss up, so life not withstanding. I still found the lookalike lights to perform poorly in the #1 area they are not suppose to... that is lighting up the road. I found the standard halogen to do a much better job. The only reason I have used these types of bulbs is too match my non-hid lights (fog, driving lights, highbeams)... apart from that, my regular bulbs did a better job of illuminating the road.

Just keep that in mind when you switch out lights.
