As an extra safety precaution, you can replace your tail light backup bulb with this warning light. As you put your vehicle in reverse, anyone who might be behind you will hear a beeping alert.
Features:
Specs:
Simply replace one of your vehicle's existing 3156 backup light bulbs with this combination backup light and warning alarm. The base of the halogen bulb beeps whenever the vehicle is shifted into reverse.

Today we're going to be taking a look at part number HM20101VA. This is the Hopkins Backup Alert, replacement 3156 Bulb with an audible alert. That's to add safety while in reverse. You can replace your tail light backup bulb with this warning light. As you put your vehicle in the reverse gear, anyone or anything who might be behind you will be alerted. This is going to send out a really consistent beeping sound.
The beeping sound can be clearly heard, again, when you move your vehicle to the reverse gear. That sound will vary depending on the vehicle that this is installed in. This is not a universal application, though it does fit in any vehicles, but if your vehicle's reversible to size 3156, then this product is going to work perfect for your application. I'm going to go ahead and hook it up to our external power source that way you can see how bright the bulb is as well as hear that audible beeping alert. Here at the housing, that's where the sound's going to come out. I'll get this connected and you'll be able to hear it.
Get all the wires on there. Okay, now turn it on. You can hear that consistent beeping as well as the bright light. It's really going to send out that consistent beeping sound alerting anybody that may be behind the vehicle when we move the vehicle into the reverse gear. That's going to do it for today's review of part number HM20101VA.
This is the Hopkins Backup Alert. .

This product is really good for for my van just plug and play. Recommended for van owner
Excellent quality with a nice loud decibel warning beep. Fast shipping. Five stars from this buyer !!!!
Isn't even close to b4ing correct ! I called and was told idt was correct your website claims the same thing . Wrong !! 2014 Ford F150 uses a 921 bulb my Ford checked . If you look at the top of this page 2014 Ford F150 is listed as a fit. Wrong . It will cost more to return this than it's worth . Sorry but 1 star poor rating !!
Fast shipping. Hope to install part This week !! I'd recommend buying parts Here. No problems so far
This is a great idea! I have a 2005 Escape and I wanted something to warn people walking behind my parked car as I back up. I ordered this little dandy and was able to install it myself (I'm a 60+ y.o. woman.) Works like a charm! Highly recommend both product and company.
Hopkins Backup AlertI've had it in my truck for 6 months now and it works great.
It simply replaces one of the backup bulbs in your tailights.
They work well and are very audible. Thanks you guys!
This product is a cost effective way to provide safety warnings during construction activity. We priced other items and they were way more expensive and required a mechanic to install. In a couple of minutes we installed this item and it works perfectly. Etrailer.com has a quick and easy website and great service!
Nice idea,but it took a few bulbs to be successful. The first ones either never alarmed or didn't light up. Replacements worked beautifully and still are months later
Product was exactly what I was looking for at a very reasonable price. The only problem I had was figuring out how to remove the tailight lens (NOT etrailer.com's problem). I wanted a means of warning anyone behine my truck that I was backing up and this was perfect.
What a great product. It's nice to know that when I'm backing up I can get everybody's attention. Safe. Easy to install. Great price. Thanks etrailer I will always buy product from you.
Easy to install. So far it is working fine. Most anyone close by should hear it. However someone in a car might not hear it. I have a van with some blind spots. This is a big improvement over not having the warning. I ordered just one. I may order a second to see if that would increase the sound level. Right now I would recommend.
There was one of these installed ( not from etrailer) when I purchased my van. After a year or so it stopped working. I looked for quite some time to find a replacement that wasn't $40.00+ and E trailer gave me one. I can now feel better when backing up , knowing I will be heard and well lit . Thank you.
easy installation, works well. won't know about the light output until I use the backup lights in the dark. Good service and packaging from the seller.
Product worked as advertised. Installation was as easy as replacing a light bulb. Bulb is attached permanently. Would liked to have seen a socket so bulb could be replaced. When the bulb burns out I will replace the unit with a standard 3156 bulb and splice the alarm into the lamp wiring and leave it somewhere in the tail light cavity.
Definitely easy to install just like replacing regular back up bulb. Also, etrailer sent me the correct light for my model and year pickup truck. The whole installation process took about ten minutes, most of the time trying to find the correct socket size wrench! Only one minor issue is the back up alert sound is not that dramatic in volume while sitting in the truck and backing up. Maybe it is louder outside. In any case, this beats attaching brackets and splicing wires for backup alert as with other type units.
When a backup light went out on our Coachman Motorhome I was just going to replace the bulb with the same. Looking around online I found this replacement bulb that also made an audible sound when the vehicle is in reverse. Visibility in reverse is nearly impossible, even in small motorhomes like ours ( 24'). We have a backup camera, but the viewing range is very limited to just beyond the rear bumper. With this product I have another level of safety I didn't have before, with the audible sound.
etrailer was really good about keeping me in the loop as to where my order was in the process. Turned out it was on Backorder, and would take a few days longer to make it to me in Seattle, but they sent emails on the status of the order regularly .
Cool product and great service from seller= a good buying experience!
Very satisfied with the back up light w/alarm.
Brought 2 one for my wife's Ford freestyle. And one for my f150. Wamted tne back up alarm because we have kids and for parking lots .Easy install . Loud alarm just this morning when she was backing down the drive way I heard the alarm inside the house. Great product. Allready referred some friends to your product thanks Mike. Milwaukee wi. ??
Every week, I see in the news where some mom in her suv has backed over her own child. This alarm will catch the child's attention and give time to shout or get away. It should also work on dogs and cats. Is not effective on trash cans. ---Only suggestion: that the light blink.

OK I JUST LOVE WHAT YOU SAID OF THE TRASH CAN.GOOD JOB LIKE YOUR STYLE.pHIL
Very happy with the service I received - fast shipping, and I got exactly what I ordered. The sound level of the product itself is a bit weak. On my old pickup I had an external beeper, and could always hear it from the cab whenever backing up. This one is easy to install, but I have to listen very carefully to be sure that it is working when I back up. I would recommend getting an external beeper mounted on your vehicle if you want to be sure people know that you are backing up.

Matthew, The latest bulb works great, but the one I bought in 2018 works intermittently and not as loud. It is not dependable, Thanks.
Bulb with an audible alert installed on my 2009 Ford Ranger.
fit my 2008 canyon.sound is just right.
halogen is brite.would be nice if they
made a led.thanks for your help.
Great little light for when you don't need to wake up the whole neighborhood. I bought one 24 years ago, and the light burnt out, but the beeper still worked fine. Needed a new one. Came quickly to my mailbox.
