Speedometer light bulbs

A long time ago i replaced the bulbs in my speedometer. The lighting is terrible. Is there something I can do make it brighter? Just curious to see what other people have done or would suggest. Thanks

Just checking that you're aware the headlight switch has a dimmer for the dash lights.

I think the design of the gauges really limits what you can do to improve the illumination (backlit gauges would be awesome, but not realistic to do). About the best you can do is replace the incandescent bulbs with LEDs (still relies on reflective lighting, but at least a bit brighter).

Having said that, there are some excellent aftermarket gauges that fit the stock dash very nicely and provide more modern lighting technology. They are also pretty expensive (beyond my budget anyway).

Do you know the bulb numbers to change over to LEDs.

They are a #53 bulb. Here is an example of an LED replacement;

Im speaking from a position of experience. I tried using LEDS and it was actually harder to see than with the regular bulbs... No idea why but LEDS don't reflect very well. The LEDS made the back light portions like the bright indicators and directional signals brighter but didn't improve the speedo face illumination.

LEDs are by nature a much more directional light source than incandescent. If you use the bulbs with a built in diffuser, it's much better in this type of application. My speedometer is much easier for me to read now than with stock lighting.

This is probably what I'll do next:

I saw these lights at autozone.

I wouldn't use those gauges though...

I would run a Dedicated ground to one of the nuts that hold the speedometer in the dash. This would run from battery Negative , or a central grounding point that is direct to the battery negative.

I used the LED's for a short period of time in the Speedometer, changed the look of the lighting to a point that it did not match the OEM look. Instead of a greenish OEM light output, it became much whiter and to me it didn't look right so I removed them. Plus, they really didn't make the face of the Speedometer brighter for viewing either.

I was thinking of removing the Speedometer housing and either painting the inside white or powder coat it in 'reflective chrome'. I think I have seen someone on here that has painted the inside of the housing white before.

Just leave an open spot for the grounds.

I think the white paint was used on the turn signal housings or tail lights.
Worked well
