@momin,
bro i know the osram are far better than the narvas but the narva ones costs only Rs.800 which i think is very cheap for such bulbs. as soon as i got them fitted in my civics i felt the diff then and there, the light is more whiter plus the beam reaches more far so as a result more time to react in hard braking. plus i checkd the osram global site and only the nightbreaker bulbe to be in H4,H7,H11 and H3. and i don't know whether anyone of these ca be fitted in civics 04-09.
