I had just changed my passenger side headlight casing because there was condensation inside. The headlight's bulb also flickers whenever I turn it on. A few moments later, it would just go out.

Does anyone know what K the HID lightbulb is? I'm looking to replace it but the factory one's a little bit expensive. I've called several Acura parts dealers but they only gave me a part # (33116-SL0-003).

Not so sure you need a bulb but might need the control for the lamp.Condensation will damage the electronics in the control box affixed to the lamp housing.
