Title: Replace Old Bulbs?
Post by: acbrock on September 12, 2023, 21:08:05
Hi, so I have taken the Instruments out of my car to clean and repair.   They are all looking awesome, just waiting on a repair to the speedo.  I was looking everything over and thought I would post this question to the forum.  So before tearing it all down all the light worked fine.  I can review them all now and make sure they are still ok.  But my question is should I replace them all even though they work?  I would have to bet 100% that this is the first time these instruments have been out of the car since it was built in 66.  I would hate to put it all back together and lose a bulb down the road?  or are these old bulbs better that anything I can get today?  I have read that some people have gone to LEDs since they should last a long time?

Any thoughts...
Aaron

Do you do enough night driving for it to matter?  Many people strictly avoid night driving for a variety of reasons.

My car hasn't run in a while, but when I drove at night I didn't mind the soft dim light of traditional bulbs.  I'll be replacing bulbs with stock bulbs when my instruments come out.

If you drive a lot at night, maybe the LEDs are for you.  That's a personal choice.

The light dimmer control works on a rheostat - an arm sweeps across a spring to vary the voltage (or something like that, I'm not an electrician).  Often corrosion builds up on that spring, so clean that if you can.

While you have everything out and the bulbs are easily accessible, I’d change all of them. It’s what I did when I had the dash apart. I also carefully cleaned and polished all the glass and chrome on the dash and replaced all gaskets.  I did not, however, change to LED bulbs but many here have.  If you like brighter lighting, you might want to consider them.

I replaced all the dash lights on my Lancia Fulvia when I restored it with small NOS bulbs since access was excellent then. Cost maybe $6 for the lot of 14 or so bulbs. I prefer not to convert to LED on classic cars.

Cool thanks everyone!  I will replace them and NOT do LEDs.

Don't forget to clean your dimmer.

The alternator or charging light should only be replaced with a standard incandescent light bulb - I'm told LED won't work. Has something to do with resistance in the system, I guess.
