I ordered these bulb to replace the light over my range hood and the light in my shower, which is a wet light fixture, for my new RV! Talking about bright....these little lights went above and beyond my expectations for an LED bulb! They put out more light than the old 921 bulb! They do have a very, very slight blue hue to them that in not noticeable unless you are looking at it along side the 921 light, which has the yellow hue! I love these bulbs and will be ordering more of them! If you are looking to replace your, old incandescent 921 bulbs then these are the solution! They are about and inch and one fourth long and fit great where your existing bulb is! If they do not light up take out and rotate 180 degrees. Also, if they still do not light up you may need to bend the contact wires out some so that they make a good connection. You may need to play with them to get them installed to make the contact perfect but once you do you will be wanting to replace all the 921 bulbs in your RV!The 921 barely lit up my stove top and this light gives off plenty of light! I love them! You won't be disappointed in these bulbs and you get 2 of them for about $7.00 so you can't go wrong!Just remember to have a little patience when installing them and make sure that you have them in properly and that the wire contacts have been bent out a little prior to installation and rotate them if they don't light up! Don't return them before you take time to install them properly!!!Going right now to order more!Our RV battery is going to give us many more days of use before having to recharge it because of these wonderful little miracles!!!Happy RV'ing!!!!

Used it for a replacement bulb in rv. light is nice and white and you can read by it. Some of the led bulbs are a blueish light that are hard to see with at night if using it for inside light. I bought some more for the cabin of the boat and really like them. Not as bright as the incondesent bulbs but they work good. Power useage is very low which is the reason to change.

Nice and bright bulbs, makes a big difference in the light, the factory bulbs look yellow compared to these bulbs.

Very bright but do not fin any if my T10 light assemblies.

The listing says these are compatible with 939 bulbs, those commonly found in Commercial Emergency light fixtures. Despite the seller's description, I asked a question above, to which the seller said they are compatible with 939. I took the chance and ordered the bulbs, and sure enough, they do not work. Picture on the left is my fixture with a conventional, incandescent 939 bulb. Picture on the right is with this bulb in the fixture. These bulbs do indeed fit in the socket, but do not illuminate. I believe the issue is that these are 12 Volt bulbs, whereas a true 939 bulb is 6 Volt.Oh well, hopefully others can learn from my mistake- NOT COPMATIBLE WITH 939!!!Seller- please update this product listing. Better yet, make 939 LED bulbs that are priced the same as these!

Low cost and money saving replacement lamps for the old Incadecent Lamps they replaced. These LED lamps produce a White light brighter than the Incadecent lamps they replaced and use less Wattage. Which saves money. They also operate at a Cooler Temperature. Great buy.

Works great for our RV range Hood. We leave our hood light on for a nightlight basically and didn't want to pull anymore power than we had to. Gave a couple extras to my Dad for his unit and he liked them too. Just make sure you have a good connection if you suspect a bad bulb. I initially though a couple of mine were duds, but after pulling them in and out a few times, making sure the wires were aligned with the contacts in the sockets they worked fine.

These are a great replacement for their incandescent counterparts. Because they are so efficient there is very little heat to dissipate and so no overheating issues as with the factory installed incandescent lights.I installed these in my popup camper because I wanted to reduce the heat generated and use less of the battery when camping. These achieved both of those goals for me.I used them in two overhead light fixtures where each used two bulbs so it worked out well. Could also use these in place of some of the clearance lights on the outside of the camper.
