ive heard from most people that the aftermarket projectors suck for light output... they usually use a H3 bulb for the low beams, which are not nessecarily suited for main headlights. Ive also heard that you go through bulbs like you read about... something about the projectors are not designed well and they burn the bulbs out too quickly.

I rode in a friends 5th gen accord with projector headlights, at night, and the light output was nothing to brag about... I think you should stay with the stock lights, especially cause they have a nice glass lens!
