FUNCTION

921 HP36 is a direct replacement for any 921 size halogen bulb. These are recommended for 3rd brake or underhood lights. 

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.

 

BULB DESIGN

HP36: Full 360 degree illumination with 36 High-Power Samsung LEDs. Aluminum base for optimum heatsinking, and non-polar design for easy installation.
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, bright, white hue for maximum light output.

 

BRIGHTNESS

210 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.

 

QUALITY

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.

    I use these for my 2015 STI as the reverse lights that go along with the tail as turn module. The bulbs are very high quality and distribute the light evenly and the output of these bulbs to the stocks ones are no comparison. I would definitely recommend the HP36 to those looking to upgrade their bulbs. (Posted on 9/2/16)

    I like diode. Eh make lights and is a cool guy that doesnt afraid of anything. Retardation aside, the lights look great on my '17 WRX: I replaced the halogens in the C light with these and I can really tell the difference. It lights up much like the limited model and is the closest thing to getting the limited lights without getting more expensive stuff. I was installing them and accidentally dropped one in the engine bay and couldn't find it so I had to order another single one. I couldn't tell that they were 2 separate LEDs when I ended up installing them. Time will tell how long they last now... (Posted on 9/2/16)

    Quality

    I bought these to replace the stock halogen backup lights on my Focus ST. I am very happy with the purchase, they were plug and play and I didn't have a single issue with the install. The color temperature is very white with no blue or purple tint to it like many cheap eBay LEDs. The brightness was slightly brighter than stock without being too blinding at night for people behind me when I reverse. (Posted on 2/4/16)

    I had purchased a set of led bulbs from wal mart for the cargo light on my 06 dodge ram, needless to say they werent very bright at all. i was waiting for these bulbs to come back in stock at diode dynamics. When i installed them on the truck, the difference was like night and day. i can actually see not only in the bed of the truck, but the surrounding area. I will never buy cheap LED bulbs again.

    Installed as reverse lights on an Acura MDX. Very high quality construction. Easily fit into housing. While illumination behind my vehicle seems about the same compared to OEM, the bright crisp pure white color added the style I was looking for. Compliments my LED brake lights and license plate lights very well. Great value and excellent alternative to OEM lights. (Posted on 2/15/15)
