    In the next few weeks, I will make one of my periodic dives into/under the instrument panel of my Series II 330GT. Anyone have recommendations for replacing the lamps there with LED's?

    While I'm at it, any recommendations for LED replacements for

    The lamps above the B pillars;
    The lamp in the glove box;
    The lamp in the trunk;
    The lamps in the engine compartment.

    Lowell I tried LED's in the B pillar lamps and thought they were hotter than the old festoons.
    you see many of these lamps with burned/buckled lens so they will not take any extra wattage.

    Just out of curiosity, why LED instead of correct, new OEM type incandescent bulbs ?
    Personally, I’ve never seen worthy advantages in having LED bulbs in vintage cars, but some seem to disagree...

    The lamps that light the gauges are very dim, and they are hard to read at night.

    Other lamps are behind plastic and can turn the plastic brown because they can get hot.

    The lamps for the engine are not very bright. But I would not replace them with LED's that have a strong white color which is not the warm color of incandescent lamps.

    Don’t discount the value of maintenance. Clean any contacts you can access...especially grounds. Time adds resistance...resistance decreases voltage (ohm’s law) which decreases brightness. Electricity is notoriously finicky...parts that “look okay” can easily be problematic.

    The modern LED bulbs have issues of their own...not so much the festoon style, but the bayonet mounts can be problematic due to the increased mass of the bright end. As you drive, the bulb bounces up and down...causing the mount to bend apart which causes more contact issues.

    A friend looked for LEDs with mini bayonet base to fit the instruments but could find none.
    The bulbs need to be the same diameter as the base he tells me.

    Lowell, try replacing the old incandescent bulbs with new ones. Incandescent bulbs get dimmer over time before they burn out. This is in contrast to incandescent bulbs that have halogen gas in them. Those stay bright until they burn out.

    Here's some tech info. You can email him questions.

    These have a higher candela rating.

    When was the last time entire wiring system, including all its connectors and grounding contacts, etc were thoroughly cleaned/serviced, re-crimped and tightened ?
    Within 10 years ? 20 years ?
    In (vintage) cars not driven/used frequently, I would recommend doing this every 10 years or so, maybe even more often if the car is subjected to humid long term storage conditions. Corrosion/oxidation never sleeps.

    I had by pasted the rheostat but that made no difference on my Daytona as you could not read the dials at night.
    I then had the garage change my Daytona instrument bulbs to led warm light ones and at last I see the dials at night.
    It was one of the best mods I had done, so stick with it there are bulbs out there that will do the job.

    Sorry Lowell, but that’s not answer I was looking for.
    I too live and enjoy my vintage cars in quite dry climate, thought never been afraid driving any of them in cold/rainy/snowy conditions, but that doesn’t mean they’re not afforded periodic/scheduled maintenance & services.

    I would definitely choose warmer LEDs if you want to go that way, Lowell.

    I love that warm glow from the instruments, whether it was in my 330 or my Porsche 993.

    My Pur Sang Bugatti doesn't even have interior lighting!

    My initial question was merely an attempt to shed light (pun intended) to often ignored, but very potential causes for variety of electrical problems in older (vintage) vehicles, i.e. inadequate wiring connector contacts.
    Having worked on hundreds of vintage cars in past 4 decades, I've seen and dealt with this more often than I care to remember.

    Do you know or can you find out what are the make and numbers of these lamps?

    Absolutely - I know of at least one vintage Ferrari that burned because of resistance heat build-up. Crawling into the passenger footwell to sand/dremel all the fuse panel connections once a year gives great piece of mind.

    When I lived in the swamps of Virginia, it seemed like corrosion/crud would appear in months. Whereas now, living in Santa Fe, we say "what is this 'corrosion' you speak of?"

    Previously I co-mingled two messages in a mistake.

    I still would like to hear the place in the wiring where a resistance build-up caused a fire.

    Also how much damage was done?
