7440 HP11 is a direct replacement for any 7440-size incandescent bulb.

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.



This bulb has four 1.5W chips around the sides, to fill in the light's housing and give a great appearance and full look, and one 5W LED chip with a projector lens on top to project outward. It uses an 7440-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.



These LEDs are available in a crisp, bright, white, amber or red color.


310 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.


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.

  1. Awesome Product Review by Specular

    The LED's arrived well packaged and damage free. I ordered the 7440 HP11 but received 7443 HP11 LED's. Its not a huge deal because they fit in the 7440 socket and work just fine. Fantastic product and build quality as usual. Diode Dynamic's products are high quality! (Posted on 7/29/17)

  2. Great Product Review by Rory

    Very easy to install of course and they work great. I just wish that my Ram 1500 wasn't so finicky and wouldn't think the bulbs are out since they draw less power. (Posted on 4/5/17)

  3. Awesome! Review by Panda

    I bought these lights for my 2016 STI after installing the tail as turn module. Now my reverse lights are the hp11 and hp38! Super bright and awesome! (Posted on 3/21/17)

  4. Bright LED lights Review by John

    Installed my Red LED lights for my rear turn signal and it is very bright. Fixed the hyperblink with the resistor kit and looking great! Would buy more LED lights from here again! (Posted on 7/20/16)

  5. Combined with tail as turn module looks awesome! Review by Shamy

    Very bright white, a little maneuvering to get it to squeeze into the housing but that's about it. Great product (Posted on 4/22/16)

  6. Good Choice Review by RT2

    Very Easy to instal the bulb once you get to it. This was place on a 2012 Jeep Grand Cherokee and to get access to the light you must take the panel off. However the out put and quality of the LED is excellent. (Posted on 2/27/16)

  7. Reverse light replacements Review by Nick

    Got these because oem reverse lights suck at night. Replaced them and honestly can see 100% better when reversing in the dark with rears tinted. Hopefully I'm not blinding cars when I reverse out of parking stalls. But who cares now, no excuses that they didn't see me backing up. (Posted on 11/11/15)

  8. Great addition to Turn as Tail for BRZ Review by William

    Got these in cool white to replace the stock turn signal bulbs which can then be used as back up lights with the Turn as tail kit. Great bright white light looks great and very functional. (Posted on 7/7/15)

  9. Nice and bright Review by WG

    Bought these to replace the rear stock turn signal bulbs on my RC F. They are bright and the amber color matches (unlike other LEDs I've tried) the stock LED turn signals. Also got rid of the egg yolk look which is an added bonus (Posted on 6/11/15)

  10. Front Turn Signal Review by Front Turn Signal

    I originally ordered the SMD27 but exchanged for these. Worth the upgrade. Provides a bright clear signal to the drivers in front of me. (Posted on 3/10/15)

  11. Great lights. Review by Reddie1337

    Purchased these for a friend, tested them in my car when I got them, I might have to buy another set for me! Great light output. (Posted on 8/31/14)

  12. White LED Review by Jon

    Purchased the White LED for my G35 front turn signal. Installed with the LED Resistor to stop Hyperblink. LED is extremely bright and looks amazing in my headlights. Well worth the purchase. (Posted on 1/6/13)
