FANTELI 7443 LED Bulb Flashing Brake Lights, 300% Brighter 7440 7441 7444 7443R T20 W21W Plug and Play Strobe Blinking LED Stop Tail Lights, Brilliant Red

I do not know yet about longevity, but so far these bulbs work great. They are installed in my daughter's car for added safety, and I believe they accomplish this goal. The lights are brighter than the standard bulb, and the flashing is distinctive and attention-grabbing. Very happy with the purchase

Really cool and technically worked perfectly , however , and I was expecting this , it sent a turn signal warning to my dash and the turn signal went into hyper flash . I could add a resistor and it would solve all of this but weighing my options I would rather not splice into the brake wires and potentially cause other issues . I sent them back unfortunately so back to the old boring brake lights for now . Hoping technology will catch up to not splicing a resistor into the system to make all of this work so I’ll just wait and see . Really a great product , very well packaged and arrived quickly . No fault goes to the actual product and they are super cool and worked like a charm , thank you Fanteli !!

Great purchase. They do flash and very bright. Safety at a great price

I love these bulbs especially at night when other vehicles pull up close to the back of mine! After the first time I step on the brake pedal they back way off of the back of my truck! They are canbus so no need for the resistors! Plug and play! Also they are supper bright! Great price also! I highly recommend these bulbs!

EXTREMELY BRIGHT AND LOVE HOW IT FLASHES !!!! THE CAR BEHIND YOU CAN’T MISS IT. VERY HIGHLY RECOMMENDED !!!!!

Works great! Works so well that people stop at a good distance behind me.(some just go around) Great!

Easy to install. Very bright. Love the double flash before full break light to alert others of slowing or stopping.

The customer care team really cares. Of course anything that man makes can fail (especially electronics) . One of the 2 bulbs failed to work , but employee Steven was right on it , sent a new set immediately and now turn signals work well and are bright. God bless them , as He and his team are very diligent and thoughtful.

quedo muy bien en mi carro , la luz es mas intenza que un foco de haloge o, es facil de instalar

this is the second set i bought. 1st set installed in 1 car and loved them. this was installed into my other. These are amazing. Strobe is perfect, they are bright, there is no way the people behind you cannot see you brake. this should be bought by everyone!

Easy to install! Flashes in quick succession 3x before going solid Bright Red, making it visible to the car behind you!

Came within a day and early. Lights fit exactly as stated, and bright as well. I have tinted rear lights so I needed something bright and that would get the attention of other drivers hence the flashing response. Good product overall would recommend

Just plug and play and you got yourself bright red blinking brake lights. In terms of longevity. I can't comment so I'll rate it a 5 but if these fail any time soon, I'll be back to rate it a 1.
