The switch will dim the lights all the way down to off but at the max briteness they are pretty dim. Hard to see unless it is completely dark out. Any body have any ideas? Thanks

Unless you have some corroded leads or bad ground, it could just be time to replace the "peanut bulbs" (small T-3 1/4 incandescent lights) in the dash. If they are the original bulbs or have a significant amount of use, they will darken as tungsten gets deposited on the inside of the bulb reducing the light output. There are LED replacement options that should do a nice job lighting up your dash. I haven't made the switch yet because it is a little bit of work to get the dash out but will be future project. If in there, replace them all just because of the time it takes to get to them. Mi dos centavos.

The rheostat on the headlamp switch gets corroded over time. A new switch is likely very cheap and lots of work to install but will help. Replacing all the bulbs at the same time is also a good idea. The blue plastic hoods on the bulbs also get dusty and cleaning those will help too.
