Philips Automotive Lighting 921WLED Ultinon LED Bulb (White), 2 Pack

No flickering, lifespan of 1.5+ years, perfect plug and play option, super easy to install, decent color recreation index “CRI”, *EXTREMELY BRIGHT*, good compatibility with any 951 socket. This includes 168, T10, 5W5 bulb bases. If the girth of the light will fit this light will fit those bulb as replacement too. This is the perfect option for backup lights and a backup cam. At night you will be able to see anything behind you. This increases safety of yourself and the others around you. They should not throw CANBUS or bulb out warnings either as a drop in replacement for backup lights. The cost may be steep. But it’s cheaper than running over a bike or bumping into something you couldn’t see. Or another driver not knowing you were actually backing up because your incandescent lights are dim. Would be extremely bright for a 951 replacement on an interior light. Since they share the same socket design.

I got this 2 pack to use in the reverse lights of my 2023 Subaru BRZ. This bulb is a perfect fit and provides a lot more bright, white light compared to the stock incandescent bulb (see photos, although sometimes it’s hard to tell in photos). These bulbs don’t have polarity so you can put them in either way and they’ll work. I’ve used Philips bulbs for years and they tend to last much longer and work more consistently than the no name off-brands that you can find much cheaper. Philips is worth the higher price for something you don’t have to replace very often.

Exact replacement fit in 2018 Honda Civic LX sedan, much brighter than original, known brand. Easy to install. Hardest part was popping out the 2 pins that hold the edge of the light unit on the car. YouTube videos to the rescue. Super easy installation. Recommend.

Kinda bummed that Philips discontinued the original 921 backup LED lights. I had the original on another car and they are bright. Replace the 921 reverse lights on my new car with these LEDs. The color and light distribution is great on a 2018 Honda Accord. I didn't compare the brightness with the original halogen. They seems to be bright enough for regular use.

Love it👍🏻

Not sure what the negative reviews are about. Maybe an older version? But I just swapped these into my 2012 Subaru Impreza hatchback for backup lights. Maybe it's just the reflector design my car has but these are plenty bright for reversing. And frankly you don't need to see 50 feet behind you to back up.

Perfect fit for Honda Civic backup lights. Easy swap out. And no low load warnings or fuse problems.

First off, these bulbs only have two main led chips front and center, one on each side, not six (three on each side, like in the pictures. Maybe this is a newer style, a revision? The photos should be accurate to the product. The oe bulbs reflect much brighter due to position of the element in relation to the light assembly reflector than due the led chips of the new bulbs. I am going back to the oe bulbs unless i find another led replacement bulb with more led chips to reflect more light and closer to oe light pattern which is wider spread. I will add that as expected the led is whiter, but not bright enough to warrant spending the extra money and time to replace oe bulbs.
