Re: [DML] Re: Dash Light Rheostat

["Ed B." <mr.pants@xxxxxxxxxxxx>]

When I bought my car, the original rheo was toast and I bit the bullet 
to buy a "new-rebuilt" one, despite the high cost.  While it was nice to 
have the dimming control back, I was less than impressed with it's 
action/taper, as noted by others here.  Can these not be replaced with a 
standard linear potentiometer?  Why does it need to be a rheostat?
