dmastroluca Report post Posted August 28, 2015 I just purchased a 2001 Monaco Diplomat and drove it at night for the first time. The instrument cluster lights are very dim, and it was hard to see any reading including my current speed. Even with the dimmer up all the way, it was pretty dim. I am thinking about changing them out with LEDs. Has anyone done this on any old coaches? Looking for led style and if I need to get special "dimmable" leds.
