Map lights, or the pair of lights above your front seats, use incandescent bulbs from the factory, giving them a yellowish color. By replacing these factory bulbs with LEDs, you can add a luxurious and modern look to your vehicle, with a cool white color, just like the map lights on newer luxury vehicles. You can also increase the brightness with SMF4 bulbs or SMD12 Boards, to improve the performance of your map lights.
The installation is 100% plug-and-play, just replace your factory bulb!
SMF2: This bulb has a standard festoon base, with two forward-facing 5050-size Epistar SMDs. Direct replacement, plug and play.
SMF4: Standard festoon base, with four 5050-size Epistar SMD chips arranged on a rectangular panel. Direct replacement, plug and play.
SMD12 Board: This is an LED panel, fitted with 12 5050-size Epistar SMD chips. Comes with spring-loaded festoon-style adapter for direct installation. Plug the adapter into the bulb socket, then just stick the board in place with the mounting adhesive pad. The board-and-adapter design allows for extremely high brightness compared to a simple bulb.
Included in your order is TWO BULBS.
These LEDs are available in many crisp, bright colors. Cool White and Warm White are the most popular colors, for a modern look with maximum visible light.
You can also select blue, red, green, or amber to add a unique look to your interior. Please note- when ordering these unique colors, we recommend moving to the next-brighter stage for acceptable light output.
Diode Dynamics offers several brightness options so you can choose what fits you best. These options are listed by the design and the lumen output of each bulb:
SMF2: Slightly lower brightness than OEM bulbs, but still provides the crisp, modern color of LED.
SMF4: Slightly higher brightness than OEM bulbs.
SMD12 Board: Much brighter than OEM bulbs. These are bright!
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 Diode Dynamics 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 Warranty Information page.

I got the SMF4 bulbs to replace stock OEM halogen dome and map lights. I'm glad I did, these are 10x brighter than the halogens. Makes the interior have that new car feel. Now I can actually see everything clearly inside. Fast shipping!! Simple plug and play. (Posted on 3/1/16)
Great Quality and Brightness. Review by Stephen

I bought the SMF4 cool white 6000k bulbs which are very bright. The install was very easy and all I used was a non marring pry tool and needle nose pliers. I can't even explain how nice it is to have everything in the interior illuminated at night when you unlock the truck and hop in. If you are thinking about buying LED lights you should definitely get these and not get crappy ebay ones. (Posted on 1/5/16)

I bought these bulbs to replace my dull interior bulbs and I am extremely pleased with the upgrade, once you figure out which direction they go they work instantly and look awesome, they function exactly like the stock bulbs, full brightness when on and then dim just like the factory bulbs and turn off.

I love that I can see easily in my truck now. It is really bright and helpful. I ordered the 54 Lumen Bulb in Cool White. It really updates the cab at night and makes it look awesome. (Posted on 4/21/15)
Perfect!! Review by TK

I bought the SMF4's for both the dome and map lights for the interior of my 11' Silverado. These lights are BRIGHT! I love how they light up the dark interior of my truck and they do not get hot at all. Installation was a breeze as well! I think these lights will also act as a deterrent if someone were to attempt to break into my vehicle. (Posted on 2/10/15)
Super bright Review by Ben

These lights are bright and easy to install. The cool white color makes it easier to read and see what's going on inside your vehicle. They are directional so make sure you try installing them both ways if they don't work at first. I have been using these for a few months in my truck with no issues. (Posted on 1/31/15)
