Hi can you help
As soon as i put my power on the rear light is on all the time !!!
but the head light switches on and off with switch.

also there is no side light bulb in head light is this normal for a 1992 super four nc31
thanks hope some one can help me

is it the rear light or the brake light that is on? can you additionally get the brake light to light with using the brake? If not, try adjusting the rear brake light switch.

no its not the brake light. its the rear light ???

There should be no side light on the SF. The bike is designed for the headlight to be on all the time with the addition of full beam and a 'pass' flash for full beam. The ignition switch will turn off the lights off when the bike is started. It sounds like there has been a simple switch added to turn off the headlight only. Check next time you start the bike does the tail light go off?? Then turn the bike off and turn the headlight on and restart the bike, does the headlight and tail light turn off??

ok thanks will try on moday and report back mon pm thanks
i have a head light on /off switch next to the kill switch on the right hand side
the switch is marked off/ p / on

i think some one has fitted a later switch gear
i think mine should not have a switch for lights just a kill switch and the start button ???
can any help !!!!!!

Yep, exactly that, someone has added a switch to your bike as the SF dosen't have one and the headlight stays on all the time. You will need to check the wiring, I imagine that whoever fitted the switch only wired in the headlight and didn't bother with the rear lights!

many thanks mate i will get the right switch gear or wire in rear light
thanks for your help

I have a friend who does that to all of his bikes. For some reason that I don't understand he doesn't like riding with his headlight on.
