Good morning folks!
I'm happy to announce that I've been lucky enough to finally get some new LEDs for my 2014's reverse lights. @Diode Dynamics
was looking for some pics and a review, so I was happy to help.
As stated in the thread title, this review is about the 7440 HP11 LED Reverse/Backup bulbs seen here: 7440 HP11 LED (pair) - 7440 / 7443 - LED Bulbs - All Products
For all inquiries, and more information about Diode's offers, speak with their forum representative, Nick, or go here: Diode Dynamics - Mazda 6 Forums : Mazda 6 Forum / Mazda Atenza Forum
Before I give the good, bad and ugly, I'd like to say that both Nick, the forum representative, and Steve who work for Diode Dynamics are wonderfully helpful and very knowledgeable. They have excellent customer service, and that means a LOT to me.
1. Stupid bright. I mean, I've had CREEs and these easily match up to them, if not beat them.
2. Very crisp, clean light. The glass used to house the LEDs is well-made and allows the LEDs to be very crisp and not overwhelming.
3. Can be plugged in either way - some cheaper LEDs only work when plugged in a certain direction.
4. Simple install; just swap out the old for the new and enjoy.
5. They match my plate LEDs PERFECTLY.
1. Much larger than the OEM bulbs, so they stick out into the housing quite a bit.
2. Because they're so much larger, you need to either remove the trunk cover completely, or wrestle with the bulb a little bit to get the best angle to install them.
3. The housing of the bulbs has a distinct yellow layer underneath the glass and, when placed inside the reverse lights, is very noticeable and not the cleanest look from with 15ft of the car.
4. Little bit pricey, but you get excellent quality.
5. Numbers 1 - 3 are just minor and somewhat personal preference.
To start, I always thought my OEM filament bulbs were bright (which they are, for OEM), but when I put them in comparison, it was a joke at how much of a difference there was. I've seen my share of CREE bulbs, but I've never seen 7440 bulbs this bright.
The crisp-ness of the light is as important as the brightness. You can have infinitely bright lights, but ones that just spread and hurt your eyes. These bulbs are not that. The light omitted is very even and crisp. They are also super white light. I always liked the OEM bulbs because they're fairly white, but next to these, it's like holding a candle next to an LED flashlight.
All in all, these are superb-quality LEDs that I'm very happy with. The only downfall is in their pricing. While I'm getting an excellent product, it's hard to justify purchasing $60 worth of reverse lights, when $15 will do the job well-enough. If $60 is too steep a cost for you, I would certainly
recommend taking a look at Diode's other products, because they have alternatives to the LED reverse lights available.
