Unless you have a Saab 9- you should not buy these Plug and play as advertised is the third point. Even though they can be used in place of a P21W for the taillights, they tend to flicker every five seconds You should let your car idle for ten seconds after you turn it Usually, the product description glosses over the fact that they require some sort of load resistor to function, but this is not entirely true since most of its advertising states the product can replace existing components. However, only three of the four worked for me, so I am giving them two stars because they seemed to be in good condition. I think if you know what you're getting into, it will work for you, but their description might be My case was also different. One of the four was defective right out of the box (I tried the other two first and they were fine - so it's not like I messed anything up. . . ).

There is a potential negative in that the prongs on either side of the base appear shorter / smaller in diameter than There are ten back-to-back It is used to illuminate uplights). This bulb has a brilliant white appearance, so if you have a classic car or just like the look of old blue/white bulbs, these might be too much for you.

I have just purchased them, so I cannot say how long they will last. My first impression was that they do not get hot and just pop Compared to filament bulbs, this bulb is much brighter. Now that I have a travel trailer I can finally see! The bulbs do not get hot either, so I'm hoping I can notice a difference in the trailer's temperature. A filament bulb acts as though it is 3000 degrees when it is working. For the old bulbs to cool off enough to touch with my fingers before I could replace them with new LEDs, I had to wait around 6 minutes. There was a last-minute order for four more so I hope they get them soon.

The light created by these easily shines through the hood of the camper's stove. Due to their LED nature, they should last a very long time. Despite the effort to replace the bulb, it did not last more than two trips. The bulb I replaced had a frosted appearance to me when I went to replace it. There's nothing but the old-fashioned light bulb.

They were a huge improvement over the old leds on the stairs I had been using. I use these lights on a motion sensor so they turn on when you walk up or down the stairs. I have them on a timer, so they are on automatically when you get to the top or bottom of the stairs. Using this safety feature at night is a great idea since stairs can be dangerous. A static-resistant bag was placed inside the individual boxes of bulbs to prevent them from touching each other. You can tell from that that the manufacturer is taking care of the product. They are very well built, as they consist of leds within a plastic housing that is extremely durable. In fact, they could probably be dropped on the ground and My purchase has been a great success.

As a replacement for my white navigation light/anchor light, I'm using this bulb. There is no need for a transformer since it draws 166ma (2 watts) and is brighter and whiter than the incandescent bulb.

It was surprising to see how sturdy the bulb looked. The reviews of other cheap bulbs had me on the fence, so I finally decided It was a wise decision for me to do so. Next year, I'll have to check to see if they are still in tact. These are much better looking than what I've seen before.
