I drive an NL fairlane and the other day on my day it started beeping at me saying " bulb out " so last night I got my step dad out behind my car to tell me which light is out and he told me to take my foot off the brake and put it back on and I did and he came and told me that all three lights were staying on at the same time even when I wasn't touching the brake so I turned my headlights off and all the lights worked fine? But my front Parkers came on?
I'm confused.

Does this make sense to anyone?

One of your bulb filaments is touching the other filament.so pull a bulb out until you find the faulty one or your brake light wire is touching a tail light wire perhaps in your trailer socket if you have one.Hopes this helps.Kevman.

Thnk you one of the bulbs was faulty as you said ill buy a new one tomorrow night thanks heaps.
