I’ve posted before about my experience with the Morimoto XB bulbs. They are solidly built and are “fine” in general, but ended up having intermittent issues because I think our cars are just VERY finicky with the voltage range needed before having the ballast turn off. What happened with me was I think the plastic base of the Morimotos doesn’t provide enough heat dissipation so one bulb would intermittently go out. If you turn the lights off then on again, the bulb would fire up again, ie the bulb was fine. This would sporadically happen with either side, but never at the same time.
It got too annoying to deal with so I swapped the stock bulbs back in and have had zero issues.
So for this thread, I think you do get what you pay for. Granted, $200 includes the name brand tax, but you are getting better quality components/materials, esp if the bases are metal.
So I’d def be interested in hearing about the longevity of the GTs and whether there are any intermittent bulb-out issues.
