Yoper BA9S 53 57 1895 64111 LED Light Bulb for Car 12V Deep Blue

In order to replace the #57 bulbs on my 1955 Chevrolet Bel Air Street Rod, I purchased these bulbs. It was necessary to replace my interior dome light bulb with a LED replacement for the required #1004 factory bulb. This is the correct bulb for the 1955 and older cars. The dome lights on a 1956 Chevrolet. My first bulb worked great, but I bought the other bulbs from a different supplier here on Amazon, so I replaced the other bulbs following with these replacement #57 First, I checked the #1004 LED replacement bulbs that have the same style base and there were no instructions to rotate the bulb to change the polarity, so it did not make sense to me, since these #57 LED replacement bulbs have the same style base, but I followed the instruction though. It's like I had a kidney for a brain in that moment, but I was also making sure that none of the 10 bulbs were broken. With my 45 years as a retired electrician, if they can get me to rotate the bulbs to see if they will operate now, they can make someone with no experience think that this would change something, but it won't. There can be only one point of positive contact at the bottom of the base It is the brass part of the base with the two knobs on the side of the base that lock the bulb into place that provide the negative for the bulb to work, " YOU CAN'T CHANGE THE POLARITY BY ROTING When you turn the bulb 180 degrees, it looks like you're holding it. With the two knobs on the two sides of the glass and the sealed glass inside, it appears to have an outer base In the same way, the filament attached to the bulb is still the negative 12V, so even if you rotate the bulb 180 degrees, there is no difference since it is cylinder shaped and not a bulb. When you rotate the positive contact point at the bottom of the base of the bulb and the contact point is in the center of the bottom of the base, it does nothing because the contact point is in the center of the base. On an older style 12V positive NON COMPUTER CONTROLLED electrical system, the only style of bulb that can change flow is the type with contact points at each end (for example, dome light bulbs), and by rotating the style bulb, you can change flow direction Remember if you buy a LED replacement bulb for an early 12V DC positive switching system, it'll be a bit of a hassle It was the style system they used until the 1990s & In the early 2000's, LED bulbs were rotated to work on some cars, with the exception of the 1 bulb style as mentioned above. If you plan to buy LED bulbs, make sure they do not require rotation. There are plenty to choose from, even here on Amazon, so look for that before purchasing. You wouldn't have to worry about returning it to us if you did that There is the time lost trying to fix Amazon, plus the time lost trying to fix them. As long as you have an automobile with an electronic control system that does not require a positive electrical charge, then these bulbs should work great for you!.

I could not get any light out of these LEDs. The loss for me is $10, since I won't bother to return them. br>I purchased them for the console lights on my Harley. In (oil, high in The lowest part of the pedestals (the base) appeared too narrow for the connectors. Six sockets were not lit by any of them. I DO want to point out that the LEDs I bought here at Amazon with the name "GIVEDOUA" all worked fine!.

After the sun set, I was using my '63 Corvair with the original lights and when I parked, I was practically blind. It was great to have these bulbs, they went perfectly in the plug You can even dim the stock knob when it's connected to the stock switch.

Excellent lights. Very happy with them. The leds look great in my gauges, and you can see two leds and one incandescent stock light in the picture. The box includes a nice storage compartment as well.

Exactly what I needed. It was ordered for the dash lighting in my Chrysler cruiser from 1966. It's not just the speedometer but also the gas gauge, the temperature gauge, and the alternator. It was necessary to use this size lamp for the ash try lighting fixtures that would not accommodate three exposed (albeit brighter) A single SMD appears to be made well enough and to be perfect. Even with the 54-degrees, they dim a little An old dimmer of at least a year! In all my applications, the outer case ground was positive, and the center contact ground was positive. I could have reversed them to see if it worked. I would definitely.

Bulb types like these are said to be backwards by many guys. 63 F100s work well as far as they are concerned. The bulbs should be grounded well as well as the hiding. I can turn on my headlight and turn off my lights.

This worried me, as they probably wouldn't be any good. As it turns out, they are some of the brightest LEDs ever invented. The only caution is to keep your eyes off of it, because chances are they will blind you. My 1975 Honda 750's gauges and cluster control are now installed.

I highly recommend it. I replaced the backlight to an old Honda motorcycle speedometer with these, and they are direct replacements for lots of applications. It appears that the round style speedometers, particularly Honda models, will work with these. There is about 1 watt consumption in As you can see in the attached photo, I have two of them powered. Although they flicker ever so slightly, they are still visible. I did not have to worry about this for my application.
