Recieved bulbs in the time frame specified and the rep I talked to on the phone was very nice and helpful. Put the 1st one in on the driver's or burnt out side and it worked awesome. On replacing the right side however, it seemed as though the light may have flickered on for a split second then would not come on . I took it back out and up around the top of the bulb looked cloudy . There was very little space to install it and the end of the bulb may have connected with the sides of the hole and caused this malfunction . The sensitive nature of the bulbs ie not touching with fingers etc may explain why bumping the end may ruin them . I will talk to the tech dept this week to see what they think. It must be noted that the bulb was well packed and looked perfect on arrival. Chris
