Perfect. I bought a pair of these over 3 years ago to replace incandescent bulbs in my travel trailer that used this style bulb. The incandescents used a lot of power and generated a lot of heat. These bulbs have performed flawlessly. One of the best (small) investments I've made. The pair is very bright, reasonably warm (in color), and never flickers. By the way, anyone who still has incandescent bulbs in their RV is foolish NOT to replace every one of them with LEDs. In the summer when we had a lot of lights on in the trailer, it really generated a noticeable amount of heat which was MOST unwelcome. And when we boondock (not connected to 120v "shore" power), the old bulbs drain power at a very rapid rate, whereas the LEDs sip electrons like they're tasting an expensive caviar. Anyway, back to these particular bulbs. No one can know whether they will be the exact same bulbs from the exact same manufacturing process as mine that were purchased 3+ years ago, but if they are, you will not be disappointed. I did get some bulbs that flicker and are annoying, but these are NOT the ones. I'd buy these again in a heartbeat.

These bulbs are awesome and the best value I found. I absolutely love the warm white color temperature! They are slightly whiter than our old incandescents which is absolutely perfect for the dome lights in our boat cabin. Our original standard bulbs were noticeably yellow and not pleasant. Other LED bulbs we've tried are very white and feel more industrial/daylight which is good for a workshop, not for living quarters. The temp of these is right in the middle. Doesn't hurt my eyes or everyone up if I turn them on at late at night, but still white enough that I can see what I'm doing if I need to tinker with something in the galley. Super pleased!Of course as everyone says, they physically fit in the socket two ways, but will only power on in one of those. If they don't turn on, flip them around.

These bulbs worked perfectly in my 1990 Carver. While the regular bulbs are extremely hot to the touch these bulbs burn much, much cooler and the light is excellent. When you order make sure you check the type bulb you need beforehand. These bulbs are different from my other boat and required the “+” “-“ polarity direction. Kudos to the company for the pictures of the bulbs they posted because if it does not light up when inserted, reinsert the bulb 180 degrees from your first try. When I inserted the first bulb it didn’t work and I was very disappointed. Then I remembered the note in the picture and rotated the bulb 180 and reinserted it and PRESTO. Let there be LED light!

I used these to replace a 1004 bulb on my router. Since the router is AC, most of the replacement LED are 12VDC, this one will run off AC. The other reason I chose it over competing lights is that with multiple LED chips it garantees lights in every direction.The only problem I found was that the base is too short to engage into plastic socket in my router, and this maybe a problem for some installations. I had to grind the top off some to get it to engage into the twist lock. Took one star off for that.Satisfied with the performance.

Used these LED bulbs to replace incandescent ones in a boat. Two bulbs for about 1/5 the price of one bulb from West Marine.

I bought this for a stern (anchor) light to replace bulb 1004, which is stated as one of the bulbs replaced with these LEDs. The halogen bulb works; theses LED bulbs do not. I changed them both back and forth trying the standard 1004 bulb in between and after. Every time, the standard 1004 bulb works, but these LEDs do not. I contacted the seller and they responded quickly, but each time, they simply asked the same question over and over, clearly not reading my email. The final response from them asked if I tried a standard bulb...I explained repeatedly to them as I did above. I would definitely NOT recommend either these bulbs or anything from this seller. On the positive side, they are returnable, so these will go back (they may be resealed and you will receive them based on packaging) and I will find some that work.

Really bright, good idea. However they don't lock in place like the factory style bulbs

This was used as a stern light replacement bulb in a dry fixture.1st bulb worked fine for about 6 months then just became very dim.Thankfully they come in a pack of 2 so we had a spare.Bulb was dry without any signs of moisture, it could be they do not tolerate vibration very well or it was simply a manufacturer’s defect.Time will tell on bulb number 2

The light colour is almost an exact match for the original, which I was hoping for. When the lens is in place you can't tell that there is an LED bulb fitted.

Worked perfectly - replaced a bunch of 12 volt - 7 watt DCB bulbs in our building's emergency lights. These are brighter than the originals at a fraction of the wattage. Less voltage drop and longer runtimes on battery. No failures so far, will definitely order more as needed.

私は整備士です、ストップバルブに使用するために購入しましたが、W球のピンの位置(画像の所)が段差になっていない。シングルバルブはピンの位置が平行です。そしてリード線にてバッテリ－の1２V+－を接続すると全く点灯しない。注文してから日数がかかり、しかも中国から届きました。そわくひんです。

価格も良心的とても良い商品です

ソケットにもぴったりで、希望通りの温かみのある電球色でよかったです。（星5つ）あとは寿命がどの位なのか・・・？５～６年は期待したいところです。
