Excellent advice Pops, they are not L/R exclusive parts. I just did this a couple of weeks ago and they are identical parts. Just a PITA to rip both headlight assemblies out then the ballasts, but that's the only way to figure out if the ballast is bad without buying a new one. After a few times, I'm able to remove the headlight assembly completely out of the car in less than 5 minutes!
