Backup light issue 98 GC Larado

I'm having a problem with the backup lights coming on when shifting into reverse. The tranny shifts into reverse just fine but the lights won't come on unless you pull back on the shifter ever so slightly. State inspection time is coming up real soon so what do I need to do to correct this problem. Thanks for any help to anyone who can shed some "light" on this.

You have a problem with the neutral safety switch.

The problem was with the NSS. Thanks for the reply.
