hey i have a question about my gf's 2007 scion tc, i have now bought 2 pairs of hids and they arent working only the left driver side one is working.. has any one else had this problem ? i tried the ballast and the lights both of them work fine i dun owat else to do the other kid before this one didnt even light up either sides

 

Buy a relay harness. Couldn't hurt. It keeps the kit from drawing power through your stock wires. Instead, it draws power from the battery. Maybe the kit isn't getting sufficient power?

 

yea i have the relay harness its really weird
