Just to keep everything updated, I did experience a problem with one of these lights. The whole housing was cracking from the base up. I think it could have been from vibrations, but it only happened on one of the lights. It was likely due to poor construction of the molded plastic. I took it to the store only to find out that the lights DO NOT HAVE A WARRANTY. That being said the clerk did exchange it for me but I could see it being difficult to get anything covered in the future. I still love these lights, but I am worried what will happen next. However, as opposed to the rest of the HID light market, it is still likely that I could go through quite a few Checker lights buying one after the other until it would make up for buying anything else. The first one lasted about 6 months before cracking, the other has been going strong for 10 months and is still as bright as ever.
