My nephew put some fan cooled headlights in his 2008 (?) Charger he found on eBay, and then promptly got pulled over three times for too much light/excessive glare/failing to turn off the high beams (something like that). He was about to put the original lights back in, when....you guessed it. One of them started on fire.
He's fine, and the car is fine, and I think he may have actually learned something.
This time....
