Review on Alla Lighting T20 7440 7443 LED Bulbs - Ultra Bright 4014 54-SMD, 6000K Xenon White, 12V W21W 7441 7442 7444: Back-up, Reverse, Turn Signal, Brake, Tail Light Replacement by Thomas Unruh

I bought these, plus JDM ASTAR 1200 lumens 144-EX 7440, plus OXILAM backup reversing light 7440. They were all pretty good but they 2nd place were best for brightness, whiteness and a nice even pattern of light petals. Best was JDM ASTAR followed by OXILAM in third place. Like I said, they were all pretty good, but these were second best. Used in the 2016 Mazda 5 as well as the 1997 Honda Civic. One thing you should be aware of though: NONE of these three will fit in the reverse lamp sockets on a 2010 Honda Civic. Although all three cars use 7440 bulbs, for some reason these LED replacements do not fit 2010, although they fit the other two cars. Strange. I can't comment on the "durability" as I just installed it.
