Smart Fortwo Reverse Light LED


At Diode Dynamics, we carry a full line of LED bulbs, including three different levels of brightness for your reverse light or backup light bulb (1156 size). We carry the brightest, highest-quality bulbs on the market, which we have designed in St. Louis, Missouri. Your order will ship same day, and we're here if you need us for support and service. Every bulb carries with it a three-year limited warranty.

Your purchase includes two 1156-sized LED bulb, for perfect fitment in all Smart Fortwo Models.


Bulb Design


HP11: Four side-firing 1.5W-rated Osram LED chips, and one 5W-rated LED chip on top, which is projected by a lens for maximum effective brightness. The bulb is housed in a machined aluminum casing, which provides superior heat diffusion for long life.

XP80: Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.

Fitment. All three bulbs use a quality aluminum 1156 terminal, with a locking base connector and proper pin alignment, designed for exact replacement of your factory 1156 bulb.

Included in your order is TWO BULBS.


COLOR

These LEDs illuminate in a crisp, cool, bright, white hue for maximum light output.

BRIGHTNESS

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:

HP11: Slightly higher brightness than OEM bulbs. (310 lumens)
XP80: Much brighter than OEM bulbs. These are bright! (510 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.


QUALITY

LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means 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.

Congratulations on getting LED 1156s to run in a goofy Smart electrical system! I tried 3 different types and my 2008 Smart went crazy and wouldn't light them, at all. Put the bulbs back in and all was well, again. Stupid car has some goofy way of powering its taillights. My hat's off to you if you made it work, reliably, without driving the car's electrical system goofy.

Thank you!

Our newest bulb models, like the HP48, feature a unique circuit design that makes them compatible with standard and CK-style sockets. Having a non-polar design also saves quite a few headaches as well!

Nick,
I install the set of your diode dynamics in my smart. (Turn, Brake, and parking) Now the car is hyper flashing all the time. Can you advise. I'm concerned after reading, that the SAM unit is controlling the flasher function. I thought I could possibly put an electronic flasher in. However I see the car does not use a traditional flasher relay. It's my understanding that this could possibly cause a problem to the SAM control.

Thanks.
Rick.

Rick,

Any time you install an LED in place of a traditional incandescent bulb for a turn signal location, you will need to add resistance to the circuit to make up for the lost resistance of the filament in the incandescent bulb.

The Smart has a built-in digital flasher relay, which cannot be replaced with an LED equivalent flasher relay. To prevent the hyperflash from occurring on your turn signal locations, you will need to add a load resistor on each turn signal that you replace with LED.

If you have any questions or need more information, please don't hesitate to give us a call: (314) 205-3033

Thank you,
Nick C.

Thank you so much for the reply. I'll contact you in a couple of days.

Thanks Rick.
