Just purchased a kit for my 05 accord install and everything went perfect took 10minutes. I got the kit from xenonlink.com well i've noticed that the light seems to get brighter at moments but it takes a minute or two. So it's like a very faint flick. It happens whether i drive the car any amount of time and i've gone over all connections numerous times. Is it required to get the relay harness, can it be possible that it's not getting enough power?

 

my kit is plug and play, no relay kit. Sounds like a bad ballast.
