Hi Guys



Can someone recommend a 'dimmer' for the instrument lights, that will achieve this: three position switch - Off- On -Dim



Regards

You could always get a Lucas automobile dimmer. It has 3positions—   OFF    DIM  and   FLICKER

Do you mean that you want off and two fixed brightnesses (dim and full) or do you want off and an adjustable brightness up to full?



If the former, then you just need a SPDT [OFF-ON-ON] switch and a high wattage resistor of a value that gives the brightness you desire.  “Dim” goes through the switch then through the resistor, bright just goes through the switch.  We can help with resistor value and wattage if you can post specifics about your installation.



If you want adjustable brightness, then Eric Jones makes/sells a linear dimmer unit here...
