Never had this problem on my 03 Heritage, but have had it happen on my 80 FX. Completely different bikes for sure but there is a way to adjust the electronic switch that controls the light on my FX. Since you have an 06 you should just take it to the dealer and let them fix it under warranty.WJ Harley 06 said:I have been noticing more and more that my 2006 Softail Heritage neutral light does not always illuminate when the transmission is out of gear. Is there something that should be adjusted. Anyone else having this issue?
