Who has run into the problem with dim dash lights on a 65 Mustang? I replaced the bulbs with bright white LEDs. That only helped a little. At night I can barely see the fuel gauge. I have the adjustment on the headlight switch all the way up any more and the courtesy lights come on. Anyone have a solution the brighten up the instruments at night?

I think you would be better off with the incandescent bulbs than the LEDs. The LEDs do not illuminate evenly and create shadowed spots on the cluster.

I have the stock bulbs but have a 100 amp alternator. I don't have an issue with dim gauges or any other lights for that matter.

What alternator do you currently have, is it the stock 60 amp one?

the rheostat on your headlight switch might be corroded. That could cause dim lights.

I agree with the corroded headlight switch. Mind were the same way while I had my cluster out I replaced all the bulbs with regular bulbs. Switch was a mess I replaced with another used one I had. Now they are nice and bright.

Gray - are you saying you had LED's and went back to regular incandescents?

I have to strongly disagree about the LED vs. incandescent. I've driven about 25 different Mustangs over the years and the incandescent brightness pales in comparison to my LEDs. There are different brightness of LEDs and I bought the brightest ones.

I have a generator. It's an early 65, 64 1/2.

I have a new headlight switch in a box on a shelf in my garage, I got from NAPA. I'll swap them out and see if it makes a difference.

I simply took the blue covers off both of mine and installed new head light switches in both cars and made a world of difference.

No my bulbs were probably the original bulbs so while I had the cluster out I just went ahead and replaced them. And two of them were already shot.

My 64 1/2 is fine with plenty of "stock" light and the rheostat works fine from bright to no light.

Having a generator could result in dim lights. Are all the lights on the car dim? Most of these cars didn't have very bright lights to begin with.

Every car or truck I have seen that had LEDs was either less bright all together or it had bright spots with shadows. They don't illuminate evenly.
