My 2014 Altima 2.5L SL has a problem with deterioration of the coating on the RH halogen headlamp reflector. The RH headlamp is noticeably dimmer than the left headlamp. Apparently, this is a major problem with the 2013-2015 Altimas, with no help offered by Nissan. Not surprisingly. http:/
I wasted money for new Phillips halogen bulbs before I figured out the problem.
The solution seems to be to replace the entire headlamp assembly, as I believe they are a sealed unit and replacing just the projector(s) is not an option.
With that, I can go OEM for about $500 and perform the work myself and use better halogen bulbs.
However, I was thinking of going with an LED assembly to upgrade the lights.
My question is whether or not there is a requirement to change the wiring harness to support LED lighting?
I read the thread below which is why I'm not using LED bulbs in a halogen assembly.
