BRAKE LIGHT SWITCHES
All of a sudden your brake light stops working, the tail light works fine, but the brake light doesn't. So you tried changing bulbs, you checked the fuses, and changed the bulbs again. A possible solution to this relatively common problem is to replace the actual brake light switch.
The last thing you want is for a car to come crashing into you
from behind because your brake lights didn't work. The standard
brake light switches are of a considerably weak construction considering
the job at hand, basically what has happened is that one or both
of the switches has stuck 'inwards' meaning that the switch won't
close when you squeeze the brake hence the brake light not switching
is the brake switch, there are two of these, one on each brake.
Squeeze the brake hard, and look inside between the finger grip
and the bar-mount, and you can see if the small white button is
popping out. If it is, your switch may be ok, in that case check
the other one to see if it is broken.
Above: a shot of the brake showing the nylon tip stuck
in the switch housing. The mechanism has broken, either the weather
and dirt gets into them and jams them up, or the nylon 'mushrooms'
at the tip and it jams. An appropriate replacement would be a
better switch with a dust boot and a brass plunger instead of
nylon. Nylon is simply too soft a material and more prone to wear.
Above: a shot of the brake switch which isn't broken,
notice that the white nylon tip (circled) is still visible indicating
that the brake light switch mechanism still functions. Obviously
the brake light will come on if this is so, if not then you can
deduce that the fault is for some other reason, in which case
check the bulb or replace it. If the brake light still doesn't
switch on after replacing the bulb, then you may have an electrical
fault in which case take your bike to your dealer, particularly
if it is still under warranty and have your bike fixed free of
replacement switch then looks like this:
are easy to fit and just screw in with a pair of pliers. They
cost around $9 each plus shipping from Italjet USA (212) 242-1600
or you can order them via your local Italjet dealer. You might
be better off purchasing more than one, this seems to be a fairly
common problem on the Dragster, and you will save shipping costs
by buying a few of them.
