I have the same exact problem with the same exact car with the same 
exact HIDs. My left one is powered directly from the alternator through 
a 30a fuse in a yellow Si weatherproof housing. The right one is powered 
from the battery post. Every so often I tell myself to get the cap. The 
trouble is, I only remember that for a moment when I have to hit the 
button twice. It's been going on for 2 years now...
