Any ideas on why my HIDs only intermittently turn on? I had XD HIDs that just days after installation started having issues igniting. It was always one or the other bulb, but never both at the same time. I'd have to turn the lights on and off a bunch of times to get the failing bulb to ignite. After a while it got so bad that sometimes it would never turn on no matter how many times I tried, so I switched to Morimoto HIDs. They worked great for a couple months, but now I'm having the same issue. Seems to get happed more often on colder days. It's so annoying, I'm considering selling my 4Runner because I can't go back to LEDs like I had before.
