<VV> re.. dim dash lights

[Frank DuVal]

I do not know why LEDs could not be dimmed. We use a dimmer system with 
LEDs as cab lighting on a truck project at work. This is a 12 volt 
system. The brightness of an LED is determined by the current flowing 
through it, which is related to supply voltage and dropping resistor 
value. Change the dropping resistor value and you can change the 
brightness. Too bright and POP!  Just do not exceed the current limit of 
the LED and you will be fine.

Here is an example of an electronic dimmer for LEDs:

A rheostat should also work.. The range of the existing rheostat may not 
give you the results you want due to lower current draw of the LEDs.
