Alla Lighting T20 Wedge 7440 7443 Strobe Reverse Lights LED Bulbs: 6000K Xenon White Super Bright 2835 39-SMD 7440KX W21W 7440LL Flashing Back Up Lamps - Perfect Replacement for Cars & Trucks Review

Revain says they will be working on the 2019 F150 for reverse lights. Not right! It is said to use the 921st. Not a huge loss, although I installed them in my 2001 Cherokee backup lights and they are super bright! Ordered a 921 set for my F150 and everything is fine.

Compatible with 2007 Xtrail T30 Reverse, Quedaron Perfectas. Parpadean al principio pero me parece bien porque funciona una alerta a la persona o vehículo que este detrás y el brillo es perfecto a diferencia de los bombillos convencionales, lo recomiendo.

Much brighter than the Silverstar bulb, crisp white modern light. Plug and Play in my 2004 Subaru STi. The lamps look cool through the clear lens when not lit. No word on durability yet. Installed just a few days ago. I love the strobe function when I turn it on backwards. Three quick flashes. Relax.

The strobe effect is the best idea for reverse lights next to the horn. This will catch people's attention when you want to turn around. Not as bright as I would like, but definitely brighter than stock. A little pricey in my opinion, but how many other backup lights offer a 3-pulse flash?

I installed these on our 2013 Honda Crosstour last night. I am amazed at how they look and how bright they look. They blink as advertised and appear to blink in sync with each other. So far I haven't had any problems with codes or hyper firmware of any kind. Only time will tell how they hold up! So far I'm incredibly happy

These reversing lights are great! They are very bright for belaying in dimly lit areas at night and the coolest thing is they flash 3 times to alert those in the area you are belaying. I mounted them on my truck and am very happy with it. Easy installation, just plug and play. Great for security and night vision from behind!

Buy it now! ALLA has science! Installed new reverse lights on my wife's Chevrolet Tahoe and day and night are different! Customer service is excellent and helpful. This is probably the 10th set I have purchased for my truck and their SUV for turn signals, cargo, parking lights and running lights. The reversing camera works ten times better now, and I've also changed the license plate to LED. Now the police can't tell my license plate light is "dim".

I am unlikely to buy LED bulbs from any other source. I am amazed at the quality and excellent customer service from Alla Lighting. I had a small problem (it was my own fault) and I called the support team. I believe the gentleman I spoke to was named Chris. He literally walked me through a few steps to troubleshoot my phone and reassured me that if it didn't fit, they would get me the right one (since I'm in super debt in 2020 and information is limited). Highly recommended.

I have fitted these bulbs in non-original taillights. They replaced the original bulbs in my 2018 Toyota Tundra. Plugs into original sockets. When you put it in reverse they flash three times and then stay bright. I think the idea is to warn the people who will be supporting you. The lights flash at the same time. They appear very light and white. All lamps have LED spots and a focusing lens that creates a beam effect from behind. So you get a glow at close range and some sort of beam. As long…
