Video Transcript for Hopkins Vehicle Lights - Replacement Bulbs - HM20101VA Review

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. .

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!

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.

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.

Still works fine. Havent had any problems with it. Still think that it should be a little louder.

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.

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 !!

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.



- HM20101VA

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.

  • Does Hopkins Bulb with Audible Backup Alert Meet SAE J994 and OSHA Requirements
    I reached out to my contact at Hopkins who confirmed the Backup Alert with Audible Alert, part # HM20101VA does not meet either of those requirements. For a backup alarm that does meet OSHA and SAE J994 regulations as well as GSA, the U.S. Bureau of Mines and all state regulations, I recommend the Buyers Products Self-Grounding Back Up Alarm, part # 337BA107. We don't carry a backup alert that can be used to replace an existing vehicle bulb which would meet the above regulations and...

  • Backup Alarm Recommendation for a 2017 Ford F-350
    I did some checking and the 2017 Ford F-350 pickup models use a W21W reverse light bulb. It is similar to a 3156 but not the same so I do not recommend # HM20101VA for your truck. But I do have another option that would actually be easier for others to hear. Take a look at the Rear View Safety Backup Alarm # RVS-W02. You can mount this backup alarm under the rear of the truck and wire it into a reverse light wire. It is IP67 rated meaning the weather will not be a factor. It will send...

The Hopkins Backup Alert # HM20101VA that you referenced is designed to replace a 3156 bulb, which will physically fit in place of your van's 3157 but may not function properly because of the difference in design. We do not have a similar replacement backup alert bulb that's designed for the 3157 type bulb so your best option will be with a separate backup alarm like the Pollak # PK41820 that...

    I do have some options for you but Hopkins Backup Alert # HM20101VA actually will not fit your 2015 Chevy Silverado 1500 due to the type of bulbs your truck uses for the reverse lights. What you can use is a stand alone backup alarm that will wire into a reverse light wire such as # PK41820. You can mount it pretty much anywhere under the truck. The power wire will splice into a reverse light wire and the other wire can ground to the frame. I have linked a video featuring this product...

This type of bulb can also be interchanged with a 921 bulb which is a bit more common. The Hopkins Backup Alert # HM20101VA that you referenced will only replace a 3156 bulb so it will not work on your Forester. I may have a solution for you but we do not have a backup alert available that will replace the W16W/921 bulb on your vehicle. What...

  • Will a Reverse Alert 3156 Bulb Replace a 3057 Bulb
    Yes, the Hopkins Backup Alert Replacement Bulb # HM20101VA will work for you. The 3057 and 3156 bulbs are very similar with the only difference being that the 3057 bulb is a dual filament bulb typically found in blinker/tail light applications. However, a dual filament will work fine in a single filament application like your situation.

  • Backup Alert for a 2014 Ram 1500
    I believe your 2014 Ram takes a 3157 reverse light bulb. A 3156 style which is what # HM20101VA is will fit the same socket but it will not work properly. But there is another option. You can use Surface Mount Back-Up Alarm, part # BK97DB. This unit could be mounted under the vehicle behind the bumper and is easily installed by tapping into the reverse lamp circuit.

  • Back Up Alarm Recommendation for 2007 GMC Yukon XL
    The back up warning bulbs we offer are a replacement for the 3156 bulb, and your Yukon XL uses a different bulb. We do however have back-up alarms that will beep loudly when your vehicle is shifted into reverse. I'd recommend the Pollak Back Up Alarm, part # PK41851. The alarm would wire into the reverse lamp circuit of your Yukon, and would sound when the vehicle transmission is shifted into reverse. Its 107 decibel horn would be easily audible on a loud and chaotic jobsite.

  • Troubleshooting Blinkers that Only Work when Headlights are On After LED Install
    Sounds like you need to install a load resistor on the circuits that carry the turn signals. I am not completely sure what circuits you installed the LEDs on but it sounds like the turn signals so you would need load resistors like part # DI34ZR for a pair. One of these needs to be installed on every circuit that has a blinker or flasher. I attached a picture that shows how it will install on your circuits.

  • Backup Alarm for a 2013 Ford C-Max
    The W16W indicates a 16 watt bulb and also is synonymous with a 921 bulb. So in other words, W16W and 921 are the same thing. We do not have a backup alarm and replacement bulb that will fit in place of a W16W or 921 bulb. But I do have a solution for you. You could install a stand alone backup alarm, # PK41820. This will actually be louder than the replacement bulb types of alarms. It can mount underneath the vehicle and simply wires into a reverse light wire.

For a backup alert that will work properly you can use # Surface Mount Back-up Alarm # BK97DB. It will mount underneath your van and wire into a reverse light wire. This backup alert at 97 decibels will be louder than the bulb type. I have linked a video showing an example installation for you.
