Alla Lighting T20 Base 7440 7443 LED Bulbs Red Turn Signal Lights, 7441 7440LL 7443LL12V

Bright as hell but one of the bulbs fan wasn't working out of the box and they both stopped working over 4 months. I'll also say (after I was testing) if left on, these get HOT. Concerningly hot. I say this because if you're in a hot climate and get stuck in traffic where your foot is in the brake for an hour, I'd be worried how well the little fans hold up, or if they do anything at all.Otherwise, they have the legendary brightness I've come to expect if the ALLA brand, and the build materials is great.I'm hoping I just got a bad set or something. I would still buy from the brand. My reverse lights and turn signal lights are ALLAs.

The media could not be loaded.  Facil de instalar no me dio ningun codigo de error, la diferencia es notable en el brillo.

Bright! Fits like a champ. Great contrast between running and brake light LED!

I installed these on my 2020 Chevy Suburban. These have worked perfectly since I installed them 6 months ago in December 2021. I would buy these again, hopefully I don't need too!!

So, I originally purchased the ALLA Xtreme Super Bright 5730 33-SMD Taillights for a set of tail lights that burned out, so I figured why not upgrade to LED's for my 2018 Chevy . Noticed after I installed these bulbs that I had the hyper flash when using my directionals. So I read that these (the Can Bus error Free No Hyper Flash) would resolve this issue. Checked the manufacturers website and it said that they would work in my truck. So I purchased 2 sets (@ 39.99 / Set). Installed them and the problem still exists. Of course I did not test them before I threw the packages away (Total brain fart on my part - don't know what I was thinking). So, I am seriously thinking that I will just go back to the Halogen Bulbs for a fraction of the cost. I will say that these lights are in fact Super Bright - but if I wanted the Hyper Flash I would have just kept the originals that I purchased and installed for half the cost.

Sometimes still shows bulb out in dash but does not blink fast

The product works well on my Accord 2007. It does not hyper flash but that’s because I installed a Signal Relay sold here on amazon which helps with that. The lights are nice and bright and definitely are better than stock halogen.

Bought these to replace the 7442 dual filament brake/taillights on my plebian 2013 Chevy Cruze. I'm electronic engineer with +40 years experience. You would think I could make them work. However they do not lock into the socket nor do the bi-pin leads line up with the socket connections. After a while (oh just a half hour a piece) I could get the taillight function to work, but then the all too important brake light function would not work. I gave up and put the original Sylvania 3057 bulbs back in after my battery went flat testing them. Takeaway, the "engineers" that design these need to duplicate the original bulbs socket locking mechanism and bulb pin alignment.

The bulbs work perfectly on my vehicle as rear turn signal indicators. An Acura TLX 2020.
