HID were aftermarket. 15 mins after installing them yesterday I took the car out to get some lunch and got in an accident! A F-150 p/u turn left in to the front driver's corner of my 5 day old car with only 100kms on it! The only test I did was in my garage, the HID on the one light and halogen on the other the difference was night and day. Having HID's on my other cars the halogens on the TCH looks like I'm only driving with my daytime driving lights.
