Review on High Power Replacement Inverter for BMW, Mazda, Lexus, and Infiniti Angel Eye Ring Lights – 4 Outputs, 12V Female Ballast, Up to 300mm by Steven Asthana

The rigid outer casing of these devices is filled with a gel material to keep the electronics waterproof. I bought these to power my CCFL computer lights as they require the same high voltage inverter. Because I don't have to worry about water. Inside the computer case, I CAREFULLY drilled a few holes in the top of the unit to allow more airflow inside the tough outer case. Colder components tend to last longer.
