Took the car in for an MOT recently, did not pass first time, which is the first time in my 10 year possession, unusual failure, no headlamp beam pattern at all, it was all just hazy in the headlight beam tester with no defined pattern, closer inspection revealed that the silver coating inside of the Halogen conversion sealed beam lamp unit on both Left and Right looked as though it had bubbled, a kind of corrosion effect.
Taking them off revealed that the outside coating of the lens was also corroded. These are Wipac conversions approx 5 years old so yet another failure of replacement parts.
Not wanting to go to the trouble of HID conversion and the wiring headache that this could cause I searched Mini and Landrover forums and found that most where fitting Cibie H180 headlamps with 60/55 watt bulbs so ordered a pair from Minisport, even if using the Lucas or Wipac Quad optics Minisport are so much cheaper than the big 3 TR7 specialists and post and packing are very reasonable.
Now fitted and ticket obtained I need to try them out on a good night drive, then maybe next I will investigate how to fit relays to lights to protect the dash switch and fit the larger 100/80 watt bulbs.
Yep too many failing on light issues. 271,567 item failures were recorded for lights alone. Lights are often unnoticed especially when you are checking them by day. Some failures are not broken lights but bulbs with faded color. Cheers,
