Reply to "LED Lighting Upgrade for MTH Full Dome Car"

That thought as come up more than once.  I've always come upon the roadblock that the module typically gets mounted in a variety of locations, so trying to make a "one size fits all" solution is difficult.  If I were making a custom module for one specific style car, that would be practical.  Trying to make a module that will work for any brand and style car greatly complicates the possibility of an external adjustment provision.

As for measuring the power output on the bench, that's easy.  Since this is a constant current design, you can simply connect your multimeter in DC current mode directly across the DC output.  Put from 12 to 18 VAC on the AC inputs, and measure the current.  Set the current for each module the same before you install them.  The output current of the module varies from 3-4ma at the lowest setting to around 45-47ma at the highest setting, so a 200ma setting on most multimeters would be appropriate.

Using that procedure, presuming the same LED strip and the same number of LED's used in the car, all the lights will be at the same brightness.
