I am going to clean this up and move this to a new thread...

I posted that because I thought there may have been confusion about the two different circuits and their existence.

These don't have the indicator lights for charging, only the check engine light when you first turn the key on.

And since you've got it apart, you really should remove what gauges you can and paint the inside of that cluster with some silver or that spray can chrome. It's not really chrome, just a really shiny silver. It seriously helps with a dim dashlight problem these tend to have.

I did it to my '86 dually I had a few years back and it was crazy the amount of light came from doing that one little thing

I really need to get around to doing it to the burb now.

An alternate to painting that seems to work run a 168 bulb...


The difference is that the 168 will be brighter than the 194. Although it is brighter, the 168 will not last as long (1500 hrs) as the 194 2500 hrs.

The 168 has 3 candle power vs the 194 with 2. Since the 168 is slightly brighter it produces a bit more heat (3.8 vs 4.9 watts). In most situations where 194's are specified you should use an exact replacement to avoid heat damage from the hotter 168 bulb.
