So.. I had both headlamps smashed while in LA the other day, and am about to go buy new ones... and had a sudden thought. Can I 'upgrade' my 2008 to the more recent LR4 headlamps with LED Surrounds? I am into quite a purchase already... but does anybody on our wonderful forum know if this is a possible swap out? ~Thanks for feedback.

 

not possible. The fenders are different.

 

yup ^

Honestly just get the standard D3 BiXenons. They're simple and you can adjust the beams with a barn door and a screwdriver. Plus you save money over the 4 headlights anyway

 

You can but you'll have to change the two front fenders and maybe the grill along with the headlights.

You can find all the info you need right here:
