LED Board SMD12 is a direct replacement for any 194 size halogen bulb, or any festoon application. A number of adapters are included with the board so that you can choose the festoon size or 194 base size.
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 LED board has 12 SMD chips, arranged in a 4x3 matrix on a board with an adhesive backing. The board is 31mm by 45mm in dimension (1.25"x1.75"), so please make sure it will fit in your vehicle.
A load resistor is embedded to prevent blowing the board from voltage surge, and a diode is implanted to protect the board from reverse polarity. The board is wired for 12V operation, the kind found on all vehicles.
Included in your order is a pair of boards.
These LEDs are available in crisp, bright colors including Cool White, Warm White, Blue, Red, Amber, and Green.
We strongly recommend cool white or warm white for the best visibility.
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.

Holy brightness!! Review by TacoFergie

I picked up a couple of these boards in cool white for my 2015 Toyota Tacoma double cab as I was unhappy with some of the festoon options I had tried. I put two of these boards in my housing and wired up both boards to one festoon adapter. It works amazing!! It is crazy bright, in a good way! I have seen and used many other led boards similar to these from Amazon and eBay in the past. soke of those claim "500" lumens, not even close to as bright as these and the color is much better on these too. My only suggestion is the festoon adapter could be better, it works and won't fall out but it does feel floppy. I wished I could get pictures to show you guys how good they are but all I have is a phone camera for now. (Posted on 7/20/16)

Excellent lights. Very bright. Cool white for my cars doors (g37 and MDX) $28 a pair?( i needed 3 pair) A little steep but like I said if u want it its worth it.
Side note had other LEDs in doors of MDX kept blowing fuses. These did not! Diode dynamics is all that's going in my rides from now on (Posted on 1/27/15)
Excellent!! Review by Jesus

Bought this for my interior dome lights and to be honest red is the best option. Red is a perfect color especially at night in which it will not hinder your night visibility. I love them and I highly recommend again to go with Red. Excellent light output and exceptional quality bar none (Posted on 12/16/14)
