Function: 3157 HP48 is a direct replacement for any 3157-size incandescent bulb. This is one of the brightest bulbs we carry, as a clear improvement over halogen lighting. The installation is 100% plug-and-play, just replace your factory bulb. The bulb may blink faster since it uses less power, and your vehicle thinks the bulb is out- to fix this, please see "hyperblinking" section below.
Hyperblinking: The turn signals on most vehicles will begin to blink fast (hyperblink) when LED bulbs are installed. This is because the new LEDs will use less power than the original bulbs, so your vehicle thinks that the bulb is out and warns you by hyperblinking. This phenomenon will be the same for every LED bulb on the market- there is no such thing as a "no hyperblink" LED bulb, even though some companies advertise them as such.
Flasher Replacement: You may have heard of replacing a "flasher relay" instead of using resistors. Indeed, some vehicles have a replaceable flasher relay, and it is possible to replace it with one designed for LED use, to eliminate hyperblinking. However, this is only true for some vehicles. We do not believe one is available for your vehicle, because your flasher is built-in to the vehicle's computer. You will need to use resistors for your vehicle.
Resistor Kit: If you prefer not to change the flasher, you can add resistors to the bulb's circuit, and mimic the power consumption of the original bulb, returning the vehicle to normal turn signal speed. Resistors are a universal fix for any vehicle. Our resistors are 50w, 6 ohm, and come with extra-long connection wires for easy install. If you have both front and rear LED turn signals, you should purchase one set for each pair, to create enough resistance for the whole turn signal circuit. The installation itself takes only 10-15 minutes, and involves making two simple connections. Everything you need is included in the kit.
Design: This bulb has 48 high-power 3014 size LEDs, with a non-polar design for easy installation. These bulbs are CK compatible and have a diffused PC lens for even diffusion of light. It uses an 3157-size durable inject-molded terminal and will fit as a replacement for stock halogen. It uses less power and heat than halogen bulbs, and will last longer, with its engineered aluminum heat-sinking technology. A component 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 TWO BULBS.
Color: These LEDs illuminate in a crisp, cool white hue, amber, or red.
Brightness: 280 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.
