Overview
LED replacement bulbs can fit numerous vehicle applications, such as vanity lights, map lights, footwell lights and glove box lights. This 3022 LED festoon bulb replaces a variety of traditional bulbs including DE3175 and 6428 bulbs. The 30-mm bulb has 4 LEDs (3-mm) on a PCB (printed circuit board) encased in a glass envelope. LEDs are mounted to one side of the board for direct 30° illumination with no wasted light. Festoon base for easy plug-and-play installation. The energy-efficient bulb operates within a wide 9-14.8V DC range and is designed to last 10,000 hours on your car, truck, SUV, or van—8 times longer than incandescent bulbs.

Lumen meters are a great way to measure white light output but can be deceptive for colored bulb intensity. Lumens measure light wavelengths in all colors of the visible spectrum. Because multiple wavelengths create white light and colored bulbs are a single-wavelength source, colored bulbs will have lower lumen readings. However, they will appear equally as bright as a white bulb. | ![]() |

Not bad, but not the greatest
Unfortunately, these are the brightest bulbs you can get for this size festoon without going to oversize bulbs (and those would not have fit in my 2014 Corolla, glad I checked first).
Maybe later on they'll release a high lumen output LED version. They are brighter than stock, and I guess the one advantage is that if people in the back use it to read, the glare won't annoy me.
so-so
The light quality isn't great. The lumens are pretty good for a map light but the warm white is just a weird, off color. These are good for marker lights, puddle lights, that sort of application.
Response from Super Bright LEDs:
Thank you for taking the time to send us a review. Customer feedback is very important to us. On the 3022-WW4 bulbs color please understand all warm whites are not the same. If you are trying to match other bulbs or ensure all the bulbs you are buying are the exact same shade of white you need to compare the CCT (color temperature). Warm white just means it has a yellow tint and the CCT will tell you how much. You want the CCT for each bulb to be as close to the same as possible.
