JDM ASTARSuper Bright Max 50W High Power 912 921 White LED Bulb For Backup Reverse Lights

I used these to replace the 921 bulbs that lit the bed of my 2012 F-250.I first tried another brand, which ended up being too long. The 921 bulbs are 1.5" long, as are these. Any longer and the socket will not fit in the 3rd brake/bed light in these trucks.I saw some of the JDM ASTAR reviews of other sizes, so decided to pull the trigger on these.Are they expensive? Yes.Are they worth it? Yes.They are truly brighter than the OEM halogen 921s (12-15w) but with less heat, more durability, and a modern look. There are no problems with beam pattern, as some LEDs have. The color is bright white (~4300k), which is exactly what I wanted. The closer to sunlight, the better. I have Rigid LED lights throughout the vehicle and am happy that these match.Even though these aren't available via Prime (bummer), they ship via USPS First Class, which is 2-3 days. I received them in 2 days (I am in TX).I would happily recommend these to anyone looking for a high quality LED bulb that is truly brighter than stock.

I really wanted to take the time to thank JDM ASTAR for delivering top-notch, high quality LED bulbs. Many competitors claim to be the "brightest", but fall short to what this company has to offer. I even ordered multiple times, testing their expedited shipping method and they have by far exceeded those expectations by delivering earlier than expected. Thank you JDM ASTAR for these wonderful and truly bright LED's. These, along with many of your other products, are worth every penny in price.-Note: I in no way was given any discount or offer to write this review. I have shopped multiple and different LED brands on Amazon and JDM ASTAR has proven to be the winner in my eyes. I'm hoping this review helps the many other customers who are trying to decide what LED bulb is worth purchasing.The answer was clear to me.

I purchased these to replace stock reverse bulbs on a 2015 Tacoma. The color matches my bumper mounted diode dynamics stage series reverse lights. Highly recommend, much brighter than stock.

Installed in a 2016 Nissan Maxima, about 3 months ago. Lights were a perfect fit, although they were somewhat finicky regarding polarity (I had to install, check to see if they turned on when put in reverse, and if not, rotate 180 degrees). Super bright LEDs (almost too bright at night, when standing directly behind the car). They don’t help provide better lighting to the rear view camera, unfortunately, but every driver behind you or within a wide view will see your reverse lights on when backing up. Will revisit this post if they fail within a year, but so far, I’d recommend and buy again.

2.5months installed, no burnt out LEDs or flickering. My pictures show one of these installed on the driver-side and a CHEAP ebay bulb on the passenger side. These are brighter, less blue, softer spread, and broader spread. The pic from inside is dead center... you can tell that these bleed over the 1/2way point in the middle because they spread so much. This is will vary among vehicles since they all have different reflector shapes, but I think the harsh cut from the LEDs pointed straight back is the important part here. Gradual is MUCH better.They are fairly long, but work fine as reverse lights... they BARELY fit in the front corner/marker lights of my '09 Xterra.... but I was afraid they would get too hot and cause issues (since they would be on CONSTANTLY and touched the inside of the housing).One clear lens on the top of the light had come off during shipping, but I super glued it back on. Superglue WILL fog the lens, so use VERY little.If these start flickering or burn out, I'll try to report back with a life span.

I have three vehicles that use the 921 type lamp. I purchased three different versions of the JDM ASTAR Extremely bright lamps for backup illumination. The product pricing was $15, $20, and $30 per set of two. The illumination of the lamps was very comparable across all three. I did not try all three in the same vehicle which would be a better more direct comparison. However, I can assure any interested individual the lamps are much brighter than factory lamps. My brother-in-law stated they were nearly as bright as headlamps. The lamps do not have the focused beam or throw of head lamps. My preference is the focused LED black housed round version. Only because they fit the lamp base much better than the two flat or rectangular style lamps did. These have a tapered circuit board material that does not seat as fully and may vibrate out on rough roads.

These are a definite improvement over the factory bulbs in a 2007 Toyota FJ Cruiser. The light from these is very white as opposed to the warm (yellow) glow of the factory 921 bulbs. There is a good balance of light projected to the rear as well as projected to the sides. No tools are required for this upgrade in the FJ, unless you have the subwoofer which has to be removed first to access the taillight access panel.Don't get too hung up on the "50W" in the description. Power consumption was measured as 280mA @ 13.8V --> 3.9W. The "50W" comes from the theoretical maximum these 10 count 5W (max) LEDs *could* be driven at, not what they *are* driven at.The received product did not have the part # called out by Amazon, but rather X000P9ZWCN, "JDM ASTAR Extremely Bright...arking lights, Xenon White, New". They matched the posted product image as of this writing.

Bought these for my 2013 Honda Civic EX Sedan. Much brighter (blindingly) than the original stock bulbs. Installation was painless and easy. Packaging was great. I bought the red version for my tail lights, which will be in shortly.Highly recommend this product. Will update on the longevity of these bulbs.

Unbelievably bright bulb. I installed as back up bulb replacement for my 08 Ram 2500 and they fit perfectly. The light is very white and I can now see at night reversing. Also good warning to others as the brightness is hard to ignore.

Just got these lights in the mail,very fast. Put them in my 2011 f150 and damn! they are super bright. I now am able to see better backing up my long dark driveway . Going to order more replacement lights from JDM. ASTAR.

Super impressed Very bright and white light

They are bright. Make backing up in the dark with tinted windows a lot easier
