The media could not be loaded. NOTE:
For those with hyper flashing, my SUV has an aftermarket LED hazard flasher relay installed, unsure now whether hyperflash happened when the stock tungsten bulbs were substituted with these.

This is installed in a 2011 Toyota Highlander Limited, replacing incandescent bulbs which happened in September 2021. After having to replace some taillight LEDs from another brand I chose to peek at these amber replacements by Alla brand and the video speaks for itself. Like something on one's body, you only notice when something's not right. Not once have I been suspicious of performance issues done installing. Upon inspection, no loss of chip function, all chips seem to be illuminating properly. In my state we have vehicle inspections only upon used purchase or registration transfer. So after 18 months I'm still satisfied. Let me add, I've had numerous malfunctions of automotive LED lighting since doing aftermarket LED "upgrades," which makes me believe that until manufacturers begin taking pride in their products the market typically relies on cheap components. Most of us write reviews which speak to initial function which inflates the star rating, and most of these vehicle LEDs have "1 Year Warranty" boasts along with "30,000-Hour Lifespan" and more claims, to add enticement for a sale. Virtually all bulbs will keep functioning beyond the 30-day return window which is the deadline for cash refunds.

But what's most important is how they work over the long term (because, try changing bulbs to see how many cars make it a bit hard to actually change bulbs easily!

That 1-year warranty seems to be a window in which some bulbs begin failing. I'm in the middle of getting one of Amazon's sellers to fulfill their warranty claim, and this process has taken time and a level of documentation that some feel is more of a hassle than it's worth. That's the realm of this market now, where most consumers wouldn't bother filing for relief.

That said, my set of Alla amber front bulbs has performed flawlessly. I sure hope that it speaks to the company's use of decent components and workmanship because now I have Alla brand bulbs on both front and rear of my SUV. I hope that the review through such a lens adds perspective and clarity for those considering the switch to LEDs. You might even consider simply keeping your tungsten bulbs rather than take a gamble with aftermarket LED replacement. YMMV.

It shows a fault when I use the blinker but it looks great.. I can deal with the fault.

one you will need resistors for this light, the computer in the truck will not see these. Two, These lights will not give you TAIL LIGHTS... only turn and brake.

I purchased my first set in March 2018. My first bulb just went out this week. Not too shabby.

I replaced only the (4) tail turn signal and brake 7443 light bulbs with the red LED ones, I tested them out by first turning on the emergency lights, they flash normal during emergency mode, but in turn signal mode, they hyper flash. They look really red bright on the pilot. I plan to install resistor in parallel, since the 2nd generation pilot doesn't have a flasher relay.
