Questions about HID on my 04 corolla S

[karl2002m]

i installed HID 8000k on my 04 corolla S recently, (DRL not disabled) and i find out that the light will "trembling" sometime only during the daytime, or i can say the light "blink", not like the stock headlight i used to have, the stock light will be on and solid, and this pair of HID is not solid,
i want to know that if this is common for HID? or just happened in my case, some friends said it might be the DRL issue, because of the DRL.....

It's because of the DRLs. There is a DIY for disabling the DRL on 9th gen corolla.com (one word). It's very easy, just one wire snip. I did it on my '07.
