GSTOP® LITE Overview

GSTOP® LITE - Smart Brake Force Sensing Safety Device for Cars,
Motorbikes, Vans and other road vehicles.

GSTOP® LITE is a factory pre-set retrofit ELBD System. ELBD means
‘Emergency Brake Light Display’ as detailed in UNECE European
Regulations for road vehicles.

GSTOP® LITE does not interfere with normal brake light operation,
GSTOP® LITE only activates under heavy sustained braking in excess
of the preset g-force values of 0.6g and 0.8g. For comparison,
Gravity (the mysterious force that holds everything on the ground) is

1.0g

GSTOP® LITE utilises a high speed digital accelerometer to
accurately measure deceleration when braking. ‘Error Correction’
(Smoothing ;-) is applied to the accelerometer data to correct for
inconsistent feedback commonly caused by but not limited to; Road
noise, Uneven road surface, Vibration etc.

GSTOP® LITE is factory pre-set and does not facilitate user
configuration. (For the ability to tune GSTOP® see; GSTOP® PRO)

What’s in your GSTOP® box

• 1x GSTOP® LITE

• 3x Wire Connectors (2x 2-way 1x 3-way Crimp Type)

• 1x Universal Wiring Loom

• 1x Bench Test Wiring Loom (requires 9v battery - not included)

• 1x Foam Mounting Pad

Your GSTOP® LITE device comes with a ‘Bench-Test’ wiring loom. You
can use this to power up and test how your GSTOP® works before
installation. Connecting a 9v battery (PP3) to the battery connector
simulates how GSTOP® powers up when the vehicles brake lights are
switched on.

Operation and Features

• GSTOP® is inactive when vehicle is stationary

• Activation is triggered automatically by heavy sustained braking

• Activation is deactivated automatically when braking force is no
longer present

• Dual Stage Inertia Activation

• Does not interfere with vehicle bulb condition monitor

• Does not interfere with normal braking conditions

• FailSafe Design - in case of ‘GSTOP®’ failure.. the Vehicle Stop

• Light continues to function normally

• Accelerometer Smoothing ;-)

Factory Configuration

Your GSTOP® LITE device is factory pre-programmed to operate with
the following settings:

• Axis: X+ (see Direction Arrow on GSTOP® LITE device)

• Trigger.1: 0.6g / @2Hz / 2.0 Seconds

• Trigger.2: 0.8g / @3Hz / 3.0 Seconds

• Duty Cycle: 50% on / 50% o

• Error Correction: Enabled (Smoothing; prevents nuisance activation)

(GSTOP® LITE does not support user-configurable options. For user
tuning settings, please see GSTOP® PRO)

Wiring Installation

Please Note: You should be competent in automotive wiring before
attempting to install the GSTOP® LITE Module. If in doubt, please
seek the assistance of a trained professional.

GSTOP® is shipped with a 3-wire universal wiring loom.

The centre Black wire (Terminal.2) must be connected to Vehicle
ground / 0v. The two Red wires (interrupt relay) must be connected
to the positive wire that goes to the vehicles High Level Brake Light.
Terminals 1. and 3. are non-polarised, and can be connected in either
direction.

Please see the attached wiring diagrams:

Installation (Location Fitment)

GSTOP® LITE is shipped in a Factory Pre-Set to operate on Axis ‘X+’

Take care to observe the correct axis when fitting the GSTOP®
LITE Module. Please note, GSTOP® LITE should be installed on a
’level plane’ (to ensure the digital accelerometer accuracy) Tilting
GSTOP® LITE forwards will reduce the ‘braking force’ required to
trigger the EBLD Warning Flash Sequence, this is due to gravity
exerting a combined eect on the forward axis. (Please note; EBLD
Brake Warning Signalling should not be used under normal braking
conditions in order to comply with EU/UK Regulation)

Secure GSTOP® LITE in place using Sticky Foam Pad(s) included.

Trouble Shooting

Problem: GSTOP® LITE does not flash when I stamp on the brakes?
Solution: GSTOP® LITE is configured to smooth out erratic

movements that maybe caused by bumps and shocks. Heavy
braking in an instant shouldn’t activate GSTOP® LITE easily, try
braking over a longer distance with a sustained moderate to heavy
brake force.

Problem: GSTOP® LITE will only flash when I tilt it towards the
ground?
Solution: GSTOP® LITE is pre-set to 0.6g and 0.8g to activate the

EBLD Warning Signal (Flashing). Gravity exerts 1.0g, so if tilting the
arrow towards the ground activates Trigger.1 and Trigger.2 flash rates,
GSTOP® LITE is working perfectly and as designed. Contact us if you
require assistance: www.GSTOP.co.uk

Problem: GSTOP® LITE accelerometer isn’t accurate?
Solution: GSTOP® LITE is shipped with Error Correction enabled.

This means it is dicult to trigger GSTOP® LITE handheld with hand
movements, or with instant shocks or vibration. Slowly Tilt the direction
arrow on GSTOP® LITE toward the ground to test, at a certain angle
GSTOP® Lite should trigger flash stage 1 @ 2Hz (twice a second) and if you
continue to tilt GSTOP® LITE towards the ground, GSTOP® LITE should
then trigger flash stage 2 @ 3Hz (3x a second). If this is the result, the
accelerometer is working correctly. If not, please contact us for assistance;
www.GSTOP.co.uk

Problem: GSTOP® LITE wiring is so tiny, how can it work properly?
Solution: GSTOP® LITE has been designed with a 2 Amp power handling

capability. This is in excess of the rated current of typical high level LED
and/or single bulb Tail Lamps. Also check the wire size in your vehicle,
it should be a good match for the included connectors to work without
issues.

Problem: GSTOP® LITE does not work when installed on the vehicle?
Solution: GSTOP® LITE ships with a bench test wiring loom. Test with a

pp3 9v battery, if GSTOP® LITE is working correctly, it may be necessary to
recheck the installation on the vehicle.

Problem: GSTOP® LITE flashes when the tailgate is open and I apply the
brakes?
Solution: Have you installed GSTOP® LITE in the tailgate? Is GSTOP® LITE

forward arrow facing 1.0g of gravity when the boot is open? This maybe
the reason why.. ‘Don’t drive with the tailgate open’. ;-)
