Just dropped of my 2012 XFR at the shop for the some repair work. They came back with the following:

Replace Driver Side Headlight Unit (Electrical Issue)

The car only has 7K miles on it. So I am surprised that they would need to replace a whole headlight unit? Granted the car was one of the first for the model year but still.

Should I be concerned about the quality of parts?

 

I doubt they'd replace the the entire light. You'd think they'd replace the electronic module on it. If they are replacing it all it might be because Jag doesn't sell the parts separately for some reason. I don't think I'd be worried at this point.

 

SA stated it was the whole unit. Will find out tomorrow when I pick up the car. Thanks

 

Agreed, I wouldn't fear parts quality in general over a small issue.

 

The headlamps (12+) are LED. I think, like the tail lamps that the whole unit must be replaced.

 

Headlight itself is bi xenon, DRL is LED.

These headlights usually come as a unit. Very, very expensive. The headlight itself is less than half the cost of the innards which includes the beam generator and height adjusters.

One of my beefs about these lights is that they cost far too much for the marginal benefit, if any, in safety. One of the great marketing hypes in the car industry is selling everyone these high priced lights designed for night driving on crowded high speed autobahns. You just can't use these lights in North America where a significant night time safety risk is large animal strikes. Unfortunately, unlike bahnstormers, large animals frequently arrive from well to the side where headlights of any configuration are of no help. Only lower speed offers any protection from deer, elk or (god forbid) moose strikes.

 

My headlights come on instantly. I thought the Bi-xenon lamps take a few seconds to brighten fully. The high/low beam is controlled by a solenoid driven cover of some kind. When I switch high/low you can really hear it make a "bang" noise. My Nissan Leaf has LED headlamps and the Jag lights are very similar, instant on full brightness.

 

Just picked up the car. So they did replace the whole unit/assembly. I guess it must be one piece.

 

Jagular, I'll take the great headlights any day...so much better in the past and truly appropriate for a car with the pace of the Jag.

Oddly, I've seem people on the forum complain about the headlights...sure they don't move with the steering like my Mazda...but they're far from terrible!
