Stage 1: 13-5050 SMD. 13 three-chip 5050-size Epistar SMDs. Four radial panels of three chips, and a single forward-facing chip. Main body material is PCB.
Stage 2: 6W LED. Three side-firing 1.5W-rated Osram LED chips, and one 1.5W-rated Osram chip on top. The bulb is housed in a machined aluminum casing, which provides superior heat diffusion for long life.
Stage 3: 50W LED. Each of the four sides of this bulb contains two 5W-rated CREE chips, and the top is fitted with two more under a projector lens. Housed in an aluminum casing with textured finish for maximum heatsinking properties.
Fitment. All three bulbs use a quality inject-molded 921 terminal, with a sturdy base connector and proper pin alignment, designed for exact replacement of your factory 921 bulb. You will not need resistors for backup lights. Just replace the factory bulb.
Included in your order is TWO BULBS.
These LEDs illuminate in a crisp, cool, bright, white hue for maximum light output.
At Diode Dynamics, we rate the brightness of LEDs in "stages" so you can choose what fits you best.
Stage 1: Slightly lower brightness than OEM bulbs, but still provides the crisp, modern instant on/off of LED technology.
Stage 2: Slightly higher brightness than OEM bulbs.
Stage 3: Much brighter than OEM bulbs. These are bright!
Lumens. 99% of sellers online simply provide "calculated" lumen numbers based on the maximum potential brightness of the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is far from accurate, as the design of an LED bulb rarely provides the proper conditions for maximum brightness, once it is all put together. We do not provide calculated numbers, as we believe it is misleading to the consumer. Please reference our pictures for brightness comparison. We do not currently list lumen brightness ratings for our products yet- however, we've just purchased the required equipment, and will be posting accurate measurement numbers soon!
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.

Backup LEDs are a direct replacement. Just change the bulb! You will not need any resistors or other accessories.
Remove your factory bulb
- 1. Access the bulb or tail light. You may need to pull back the trunk/cargo carpet and/or unscrew the visible nuts holding the light in.
- 2. Remove the backup bulb socket by twisting counterclockwise.
- 3. Remove the factory bulb from the socket.
Install your new LED bulb
- 1. Plug new LED bulb into socket by pushing it in fully.
- 2. Test the function of the bulb. If it does not work, remove it, rotate, and reinstall in the socket.
- 3. Insert socket back into place, and reassemble as necessary. That's it!

You will receive updates from our site when your order is shipped, along with a unique shipment number to ensure that your order is correctly accounted for. This allows you to easily reply to us if you have any concerns.
Whether your order is big or small, it is tested through many run cycles, and each bulb is tested before shipment. Every single bulb. Every time. And if anything does go wrong, you can rely on our industry-leading warranty for worry-free replacement.
If you're not happy with your items, we want to make it right. So we have some pretty awesome return policies:
30 day return policy. All customers have 30 days from the date of original order shipment to return items.
Full refund, no fees. At Diode Dynamics, we offer free returns. That means no restocking fees, no administrative fees, and no hassle!
Free return label. If your original order was over $50, you get a free return label for your items (US customers only). If your order was less than $50 or international, you can send the items back through your preferred method.
Within 30 days: If your original order was over $50, you can get new items shipped to you with a return label (US customers only). If your order was less than $50 or international, we can send you the new items first, but you are responsible for returning the old items.
Within 90 days: Any item can be returned for exchange or store credit within 90 days. The buyer is responsible for the cost of the return shipping, and must first return the old items. We'll still cover the postage for the new items.
Please note: due to the nature of custom acrylic pieces, we cannot offer any refund or exchange for returned custom acrylic items.
To make a return or exchange, please request an RMA, or give us a call. When we get it back, you will be notified and credited appropriately.
Again, all returns must be approved, with an RMA. This is so that we can process your return as quickly as possible when we get it. If you would like to return an item, please Request an RMA. Please include as much information as possible about the reason for return.
