I HIGHLY recommend this upgrade to everyone. First thing I did when I bought my XJ years ago was buy new headlights and was disappointed with the results. This is what I should have done first. They are so much brighter that driving on the highway I think there is another car next to me. Close to twice as bright. Short of the keyless entry the best money I have spent.

 

I agree, this is a great and easy upgrade. It really does make a huge difference. Watch out for the putco relays though, they suck.
