K40 DefuserPlus
" K40 DefuserPlus " made by 'K40' in USA.
K40 are so confident that the Laser
DefuserPlus will protect you that on their website they say "We'll
pay the cost of your fine for any laser speeding tickets you get
for one year after purchase! but I guess this is for the USA
only.
Anyway what do you get in the pack,
1 DefuserPlus with enough wiring connected to it to go round the
world, well not quite, but you get my meaning. Plenty of nuts
and bolts, the warning buzzer, warning light, fuse holder, electrical
connections and a full set of instructions.

Above: What's in the pack?
one head with fitted wiring loon, LED, Water proof Fuse holder,
Screws Electrical Joints.
warning alarm and a very good set of fitting Instructions.
The £250.00 + VAT unit is 6" wide 1" deep and 1" high with two
windows on the face, one for the sensor and the other for the
laser diodes. It is made of a very strong plastic and well sealed
from the elements such as rain.
On opening the box my first concern
was fitting the unit, in the USA they have a surround for the
number plate that the DefuserPlus fits into, making it all look
very neat. However the unit I was supplied had no surround for
the number plate, and I guess even if it was supplied it would
have been useless for UK number plates. The wires come out from
the side, again in the US plate surround they are hidden, not
so for UK users without a surround.
So how do we fit the unit, well just
above the number plate perpendicular to the ground I have been
told. This put the DefuserPlus in a very vulnerable position sticking
out from the front of my car. Two self-tapping screws hold it
on, but this leaves it open to theft, so I suggest either pop
rivets or bolts even better would be, if you are brave enough,
to recess it into the bumper.
The instructions cover the wiring
very well, you have to fit a warning light on the dash and a buzzer,
they suggest, inside an air vent, there is no off switch you rely
upon the connection to ignition on, again I would suggest that
you add your own off switch
Overall it was easy to fit, but
I would like to see a better way of mounting it on a UK car number
plate. The current way makes it stand out far too much, leaving
it open to theft and damage from parking or other cars. Come on
K40 if you plan to sell it to the UK you need to offer us a surround
as you do in the USA.
So did it work?
We tested it against the Marksman
LTI 20-20 & ProLaser II.
On turning the ignition on the warning
light illuminated and buzzer sounded to confirm the unit was operating.
Both Laser units could not get a
speed-reading, you had more than enough time to slow down to the
legal speed limit. During the test the unit gave us a warning
via the buzzer and the light.
After the Laser gun was turned off
the unit gave a confirmation that no laser signal was being received.
With the warning light in the right
place you will get plenty of notice even with the stereo up high.
The guns gave no reading or showed
errors.
