Miniature Low Fuel Warning Light Module  (Requires some soldering)

Works with a conventional gauge
will work on most vehicles that have a resistive sender
Does NOT need a special low fuel sender, works with ordinary senders!
  • Very small size (15 x 13 x 9mm) means it will fit INSIDE most fuel gauges or Instrument panels.
  • Turns on an :LED when the fuel level gets low.
  • Switch point fully adjustable.
  • Includes Wide viewing angle Water Clear  3mm RED LED and mounting bezel.
  • Works with senders that have a high resistance when empty
  • Works with senders that have a low resistance when empty.
tested with senders from 0 - 60 Ohms up to 0 - 500 Ohms
tested with senders from 60 - 0 Ohms up to 500 - 0 Ohms.
  • The module has four connections, Power, ground, sensor and LED.
  • When fitted inside a stand-alone gauge, no external connections required
 The module has an anti-slosh circuit that makes it respond very slowly to changes in the sender signal.
this means it ignores the changes due to fuel sloshing in the tank or short hills etc.

Adjustment is by turning the small adjusting screw on the high quality 25 turn trimmer



Full instructions included
provided with double sided tape on the rear for fixing

four connections,  +12, Ground, Sender, LED

every unit hand built, and tested by us!


for the technically minded, all except the 25 turn potentiometer are surface mount components
the capacitors are not electrolytics that have a limited lifetime, but multi-layer ceramic caps that will outlast the car !
This unit is the latest in a long line of low fuel warning modules we have designed and it incorporates everything we have learned.

below is what it looks like in a TVR/Telemetrix fuel gauge.... there is more than enough room!
In the example below, the supplied LED bezel was discarded and silicone used to fix the LED
