@Robert I am sorry to hear that Robert. That is not typical with these bulbs, I wonder if it was a possible bad batch. I do know that they have a good warranty on them. You would be able to reach out to Valterra Products, the manufacturer, and get those replaced. What vehicle did you replace these in?

Not too bright and extends battery life.

Had a long search for 921 LEDs for my Nissan Frontier’s cargo light. Too bright, too dim, Kelvins too high, etc.,
I stumbled on these and the 5000k is PERFECT. These particular bulbs have the same output an incandescent does but with that perfect 5000k glow! Ultra satisfied.

Replaced my original anchor light bulb with this after trying one from the auto parts store that didn’t fit well. Jason was exactly on the money with this bulb. It fit perfectly and had the super cool white that I was looking for!

Still working beautifully!!

So far the new bulbs are working great!

These LED bulbs are great ceiling lights for my 2027 Gulf Stream travel trailer. I use a variety of lumens for the different area. Brighter (higher) for over stove top and kitchen and bath sink and "warm" for cozier areas like over the dinning table/booth and bed. The install goes well with patience and a good close look at the fixture. The "web base" is the same on all of these LED bulbs but some need coaxing.

Do you have a question about this Vehicle Light?
  • Can Gustafson 12V RV Vanity Light Use LED Lights
    Hey Mike! The Gustafson 12V RV Vanity Light # 277-000322 can use LED light bulbs. The 912 and 921 bulbs are interchangeable since they have the same T-5 wedge base. The 921 draws more power and will burn brighter than the 912 so that is the difference. LED has a little more variation since they have different lumens and colors like the warm white # DI74ZR or cool white # DI64ZR. Power draw really won't be a factor on LED lights since it is so low. Pick whichever color and brightness will...

  • Can 906/921 Bulb Interchange with 194/168/158
    Hey Rob, yes they will because all of those styles use a T10 base. So if you were wanting to use the part # DI74ZR which is a 921/906 you certainly could.

  • Recommended Replacement Bulbs For The Omega RV Dome Light With Switch
    Yes, we carry the # DI64ZR, which is a cool white light, and the # DI74ZR, which is a warm white, to replace the LED bulbs in your Omega RV Dome Light with Switch # 328-001-901XPW.

  • Troubleshooting Bulb 906 LED Replacement for Boat Anchor Light
    The 906/921 LED Bulbs - Wedge Base - 360 Degree - 215 Lumens - Warm White - Qty 2 # DI68VR sounds like it isn't the best fit for your application. The style sounds like to doesn't allow enough room for your application so I recommend using the 921/906 LED Bulbs - Wedge Base - 360 Degree - 230 Lumens - Warm White - Qty 2 # DI74ZR which has a longer taper to the base allowing for proper seating.

  • Is Incandescent 921 Bulb Normally Pretty Hot
    It's pretty normal for incandescent bulbs like the 921 bulb part # VA0415-00 to get pretty hot to the touch so I wouldn't worry about it being hot. To get something that emits less heat you would need to go with an LED like the part # DI74ZR.

  • Interior and Exterior High-Efficiency LED Lights for 2004 Keystone Cougar 5th Wheel
    LED lights will be much brighter than the standard incandescent bulbs in your Keystone Cougar 5th wheel. You can replace the complete incandescent light fixtures if you want to but you also can just replace the old bubs with LED equivalents, as you noted. We have these LED equivalents for most of the popular bulb types in RVs. All appear on the linked page. Click on your regular bulb number to see the LED replacements for it. A complete LED tail light like # 328-003-81LBM1 that you referenced...

  • Does Omega RV Double Dome Light 328-001-902XPW Include Bulbs
    Yes, the Omega RV Double Dome Light # 328-001-902XPW includes the two 921 incandescent bulbs. The rear of the light (please see the linked photo) shows the back of the included on-off switch and also the two pigtail wiring leads for making your 12V power hookup. If you ever want to replace the standard bulbs with high-efficiency LEDs that will use less power you can do so using an item like # DI74ZR, which is sold as a pair. This LED emits a pleasant warm white light and uses only about...

  • Lower Power Drawing Light Bulbs for Gustafson RV Vanity Light # 277-000322
    The Gustafson RV Vanity Light # 277-000322 that you referenced uses 921 style bulbs which if you wanted to go with a low power consumption option you can easily use LEDs like the part # DI74ZR which puts out a warm white color which is easier on the eyes. The picture I attached shows the color of the light it puts out. Each of these draw .19 of an amp.

  • LED Interior Lights that Fit 2008 Mercury Grand Marquis

  • Will an LED Work Inside the Bargman 12V RV Dome Light 30-76-123
    Yes, you can install an LED inside of the Bargman 12V RV Dome Light part # 30-76-123. It's a 921 type bulb and I recommend the 921/906 LED Light Bulb part # DI74ZR which produces a warm white light. That said, pretty much any 921 style bulb will work for you.

  • LED Replacements for Standard Bulbs in RV Lighting
    I'm glad you're happy with your Recessed LED Lights # 324-000099. These produce what is typically called a warm-white light, meaning they output light with some red hues. Warm-white light like this is typically in the range of 2700K to 3500K. This is about the same color light as produced by a standard 60-watt incandescent bulb. We offer LED "bulbs" as replacements for a range of popular RV light bulbs. Some of these LED replacements offer the warm-white output color, such as # DI74ZR...
