74 SMD1 Bulb is a direct replacement for any 74 size halogen bulb. From the factory, the bulbs are incandescent, lighting up in a yellowish color.

By changing the factory bulb to an LED, you can illuminate the area with a much brighter light, and add a pure white, luxury look.

The installation is 100% plug-and-play, just replace your factory bulb.



This bulb is a 74 size bulb, to fit in any 74 or equivalent halogen application. It is made of a high-quality plastic base with a size 5050 SMD LED. You will not find a brighter LED bulb for this application! A load resistor is embedded to prevent blowing the LED from voltage surge, and a diode is implanted to protect the LED from reverse polarity. The LED is wired for 12V operation, the kind found on all vehicles.

Included in your order is ONE BULB.


These LEDs are available in crisp, bright colors including Cool White, Blue, Red, Amber, and Green.

 We strongly recommend cool white or warm white for the best visibility.

16 Lumens

Lumens: BUYER BEWARE! Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum.

These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures. Please click here to learn more about LED brightness measurement.



LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means we use only brand-name suppliers such as Epistar, Cree, Osram, and Samsung.

While our bulbs may look the same as others on the market, most copycat bulbs use economy-grade LED chips in order to reduce costs. This greatly reduces the reliability and overall brightness of the bulb when you compare it to Diode Dynamics.

Construction. Although LED technology allows for extremely long bulb life, the market is flooded with cheap LED bulbs that fail prematurely due to inferior construction. The worst enemy of LEDs is excessive heat, and when bulbs are not designed properly, they do not disperse heat as well, leading to premature failure.

Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of flux in the solder, uneven chip placement, low-gauge terminal wires, poor assembly, and bulbs held together with inferior adhesives. At best, solder joints will crack and fail on low-quality LEDs after a few weeks of use. In the worst case, these bulbs can damage housings as the extra flux and adhesive evaporates and creates a residue on the lens of the housing.

Diode Dynamics bulbs are produced with modern, computerized equipment, and only the best materials, to ensure complete uniformity, high quality, and long bulb life.

All Diode Dynamics products come with a 30-day satisfaction guarantee and a 3-year limited replacement warranty. For more information, please view the FAQ guide.

  1. Looks and works Great Review by Michael

    Ordered a set of these lights in 6000k for my 2015 Mustang EcoBoost. The are a perfect complement to my LED dome lights and give the interior a cohesive look. (Posted on 7/9/16)

  2. Great product! Review by Nicholas

    So this is a fantastic product from Diode Dynamics. The blue tint that I ordered is a beautiful accent to my mustang. It gives it that personal feel, while still allowing me to see. The blue acts a bit like a black light, so do keep that in mind if you're not a fan of those. And follow the demonstration videos! I watched the video but ended up having to replace two fuses anyway, my fault not theirs. But I will say, the vanity lights are kind of a pain to install. It you know someone who can, I'd ask them instead of trying yourself. With all that said, I can't wait until my next order from them! (Posted on 1/29/16)

  3. Vanity Mirror Lights Review by 11 Ford F150

    Replaced Vanity Mirror Lights.
    Not as bright for the LED light barely reflects forward for the LED is sitting sideways.
    If the led faces you it would be much more brighter!
    Still gives out about the same amount of light as OEM but in better LED color. (Posted on 1/22/16)

  4. Bright Blue Light (05 WRX) Review by Jason

    I bought and installed two of these bulbs in blue. One in the ignition ring and one in the ask tray / cigarette lighter. The ignition ring is impressively bright and the prefect shade of blue. With the LED in place the ask tray is no longer illuminated, but that's what I wanted. The cigarette lighter is still lit very clearly. (Posted on 12/11/15)

  5. 2003 Subaru Forester instrument cluster Review by Nathan

    I purchased two of these to experiment on the lighting of the product. It was astounding how a little LEDs could make so much light. Installation was a breeze and it fit just like OEM so I was happy. I had to install these in a different area of the gauge cluster because they were so bright. I moved them to the odometer backlight and it was perfect lighting! (Posted on 8/27/15)

  6. Extremely Bright Review by Anthony

    This is exactly what I needed for my gearbox in my '08 Fusion, stock bulb just wasn't cutting it with custom painted gearbox. Great work everyone! (Posted on 7/31/15)

  7. Didn't fit :( Review by oski83

    Ordered to replace bulb in glove box on my 2015 WRX hoping it was same as previous wrx models but new 15s are in fact different. Quality is still there from Diode Dynamics but bulb will not fit newer 2015 wrx. No biggie as its only less than $3 bucks (Posted on 6/20/15)

  8. great price Review by leoh007

    This LED works for the drivers side foot well of a 2015 Tundra SR5 and it fits like a charm. Install was easy and bright as always! (Posted on 6/10/15)

  9. Replacement for OE Honda Motorcycle Dash Bulbs Review by Michael

    I purchased a complete set of warm white 74 SMD1s to replace all of the incandescent dash bulbs for my 1985 Honda VF700F Interceptor. The form factor of this LED is a virtually identical replacement, being just *slightly* larger. It makes for a nice, snug fit, but not overly tight.

    The light quality of the indicators (dash turn signals, oil pressure, high beam, etc.) has a crisper, starker quality, but is certainly more eye catching then the more diffuse incandescent illumination. The tighter focus of the 5050 SMD (120° angle) shows through the dash lenses with a brighter, central hot spot. As I stated I replaced all my bulbs with warm white LED, however I am now curious as to how the appearance would change when using color matched LEDs (i.e. yellow LED for turn signals, green for neutral, etc)

    With longer and longer days since I installed, I have yet to view the ambient illumination of the dash at night, which is what prompted this project in the first place (all of my incandescents for ambient illumination were burnt out.)

    My one issue was with polarity. As you may know, LEDs are polarity sensitive. Luckily I made sure to test the dash before full assembly on the bike. If an LED was lighting, I would simply rotate it 180° in its socket. Viola! Light! A clear method of marking cathode/anode would be appreciated.

    I love this modification/upgrade for my bike, especially since bike dashes (like these LEDs) are not dimmable. I am considering doing a similar upgrade for my classic cars, but only for full-strength indicators and not ambient dash illumination (Posted on 6/4/14)

  10. Great! Review by Jimmy

    Bought four for the vanity mirror/visor lights in my '06 Subaru. Wasn't sure how well they would work since the bulbs in my visors point out to the sides. These are bright enough that it wasn't a problem! I jammed some aluminum foil behind them to reflect the light out and now they're REAL bright.. ;) (Posted on 8/23/13)

  11. Nice bulbs! Review by Dom

    I put one in my glove box and it looks much nicer than the stock amber bulb (Posted on 5/23/13)

  12. Very Pleased Review by Aaron

    Ordered two of these bulbs, Replaced OEM bulbs in my Forester's ignition ring and ashtray. I am very pleased with the output and quality. The colot is brilliant and accurate and they are brighter than OEM, but not bright enough to distract. Not to mention, customer service was excellent! (Posted on 2/11/13)

  13. Very nice Review by Kostas

    Fantastic product !! (Posted on 10/9/12)

  14. Nice looks! Review by jackson

    bulb looks awesome! used as a replacement for my ignition ring. way better as red than that gross green! (Posted on 6/12/12)

  15. Good bulb Review by Jim

    This was a good replacement for my ashtray bulb. Bright and disperses pretty well for a LED. (Posted on 11/25/11)
