Pontiac Solstice 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 (3156 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 3156-sized LED bulb, for perfect fitment in all Pontiac Solstice 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 inject-molded 3156 terminal, with a locking base connector and proper pin alignment, designed for exact replacement of your factory 3156 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 your needs best. These options are listed by the design and the lumen output of each bulb:

HP48: Similar to factory brightness (280 Lumens)
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.

FWIW (I don't have any of these) I retrofitted Philips 10W, 500 lumen fan-cooled bulbs in my reversing lights and frankly, they are TOO bright. However, they are forward-firing bulbs, whereas these are side-firing as well. Given that our reversing light reflectors are not that efficient (just silver paint), the effective output of the brighter bulbs here, may be just fine - bright, but not blinding. Certainly these will be FAR easier to install than my customized ones were! :)

I recall seeing your post before about these housings. Output aside, I definitely like the aesthetics of the housing you selected vs. the split factory look. Very impressive!

You say '5 Watt rated' or '1.5 Watt rated', but no where do you list the actual power or current drawn by these bulbs. Can you provide that info? For example, does the XP80 actually draw 65W?

We will have more specific technical information available on our new site when it launches in January.

However, I did test a 1156 XP80 to get that information for you

They use .75 amps at 12V, so 9-10 watts

I suggest watching this comparison video if you haven't already:

So, the 5 Watt rating is the typical 6X LED equivalent, just like the ratings on household bulbs. That means the XP11, being 29W rated, actually will draw approximately 5W.

Interesting that you control the temperature response actively; good to know.

Correct, LED efficacy is the same whether home or automotive, so currently, an LED drawing about 1W can replace a 5W incandescent. Such is the case for 5W T10 bulbs. We do have options that are considerably brighter than the factory bulb though in most applications.

Luckily most of the LED ICs out there now have capabilities to tie in thermal controls. However, it's really only for our higher power bulbs, where it is a concern, and of course only on newer products.

I've never seen a back up light that actually lit the area behind the car. pretty much useless except for otherws being able to see that you are backing up. I like TS idea of converting them into Qbeams. That's what I want.

If output is your main concern (aside from cosmetics) the XP80 will produce about 3 times more usable light output than your factory bulb. It's a substantial increase for a plug and play bulb, but changing the housing out looks pretty cool IMO

Cool. good to know. I'm going to convert mine to the HHR's but will keep the factory bulb set-up so when I'm ready, I'll give the XP80's a shot.

Any estimate on when more XP80s will be available?

I got the 'in stock' email, and ordered a pair; looking forward to testing them.
Great video, BTW.

I just tested the XP50 (narrower version of the XP80) in my wife's Vibe, in our black hole of a driveway. Very white and bright lights, making the area much easier to see! I expect the XP80s for my Solstice to make the same improvement.

Installed the XP80s tonight, turn the car on, put it in reverse - no light.:cuss:
Pulled the tail lights out, again, reversed the LED bulbs, put it back together, and tested in a dark garage. Very bright, white light; way better than the bulbs I took out.
