I had to use these for my halo projector headlights in an 01 honda civic. SO HAPPY WITH THE RESULTS! the previous HID kit that i had started to dim. then one bulb started flickering until it stopped working completely. when i bought these i was sceptical but they are so freakin bright!!! i can see twice as far as i could with my previous setup! took two hours to install with my girlfriends help. saved 100 bux on install.
if you do get these however you may need to get a relay. sometimes when you start your car with the HID healights on it will kill the ballasts if you dont have a relay. this happened to me. if you blow either ballast you might blow your low beam fuse as well. causing other lights not to work such as your dash lights, running lights, headlights. replace the fuse to get those lights working again and buy a new hid kit. also turning the HID headlights on and off quickly can cause them to have a shorter lifespan. they sell relays and single ballasts at xtremehids
