I think you are describing a vibration, not a power issue. I have the same kit. only my passenger side high beam does it. Look at the part of the bulb where the glass goes in to the metal ring. If you look, when you turn the high beams on, the bulb will retract into the metal ring. The bulb does not fit tight when they retract. therefore, causing a vibration. To put it bluntly, you get what you pay for and DDM is cheap chinese shit. (Not dogging yours, again, I have the same kit) and I must say for the price, I still think they are a good buy. However, take a look at what I described and see if it is what you are talking about. If so, i think the only cure is to put in a new bulb which may do it as well, or live with it. You could try e-mailing DDM and waiting 4 days for them to tell you they wont exchange it, but it may be worth a shot.
