Alla Lighting 1300 Lumens 21W CREE Extremely Super Bright 6000K Xenon White 7443 7440 7441 W21W 7440NA 7444NA WY21W LED Bulbs for Turn Signal Blinker Light Lamps Replacement

This is very bright. I get no hyper flash at all. The good thing about these is that built in resistors are in the driver , so the bulb doesn't get hot after leaving it on for some time. Other bulbs with built-in resistors usually get hot and they hyper flash after leaving them on for some time.

I installed these several days ago and they are fantastic. No load resistor needed on a 2018 4Runner Limited. Quality seems great, so I hope that they last. Installation was a breeze. Rather than the normal twist to lock the bulb assembly in, these come with a soft silicone type rubber grommet and you simply push the bulb into the housing until it is seated. Just make sure that you twist the bulb assembly back and forth a few times to make that that the silicone has inserted all the way in is "seated" into the housing. When it pushes all the way and seats, you can "feel" it grab. The silicone grommet also glows green I noticed. Not sure how this would really apply at night since you wouldn't necessarily have your blinkers own long enough for them to charge up. Great LED blinkers. Cheers
