Dynamic Lower Fairing Inserts are a direct replacement for the Harley-Davidson® lower fairing radiator grills or filler plates. With more than 130 White & Amber LEDs per side, the inserts produce a bright white running light with amber turn signal that’s virtually invisible when off. When the turn signal is activated the white DRL running light turns completely off providing greater visibility to the amber turn signal. Unit simply snaps in place with plug and play wiring for easy installation with open honey-comb grill to allow air to flow through.

I have been lusting after these lights since I first brought my Triglide home. I loved the look, style and function of having the additional lights in that unused area of the lower faring vent. And to incorporate the amber turn signal there makes it much safer. I finally ordered them and received them promptly and with everything I needed to do the install. I'm not very mechanically inclined, but the instructions, the on-line videos, and some common sense made the install a breeze. One word of warning for the novices like me. I followed each step of the instructions...#1 thru the last. Then I saw the warning, 'Disconnect battery before installation.' Why wasn't THAT #1? Anyway, all went well and I now have the bike looking like I want it. It looks great!
They look great on the bike simple install. Quick delivery.
Super bright. Snap in installation and straight forward wiring. Easy to daisy chain with other great Custon Dynamics products with the plug and play design. I am very pleased.
This outdoor be a 5, except the instructions aren’t really clear in some areas. A little common sense and it’s not a problem. Love the looks of these, and the extra security of being seen by others. Looking forward to a night ride to check out the difference there. Definitely recommend them!
The lower fairing lights look and work great on my 2014 Ultra Limited! When the bike is off, you can barely tell that they're there, but when it's on, the lights are really bright and help make it more visible at night. Custom Dynamics products are second to none and I highly recommend these!
I installed these on my HOGWORKZ lower fairing. Even though the website only gives you 3 options of lowers these would fit. They fit perfectly on my lowers.
Installed is easy except when you are installing the DRLs. Not clear instructions and I have a street glide. Not a lot of videos out there that show you how to do it. Just know that the left and right DRLs will connect together on a plug on top of your fairing.
As anyone who is familiar with custom dynamics has come to expect, these fit great and look great. Installation is very easy with plug&play connections. Will definitely be more likely to be seen with these.
I've had a set of these previously on another HD. Making yourself visible to other drivers is of the utmost importance for safety. These do the trick. If you are a DIY'er these will be fairly simple to put on. They add great visibility to the front of your motorcycle and of course, are another high quality product from Custom Dynamics!
Perfect fit, super easy to install and very visible. Custom Dynamic products are the best and the life time warranty is a huge plus. Had three led’s out on my windshield trim called customer service on Tuesday explained the issue, sent a picture they shipped out a new windshield trim that day had it on Thursday!
Fairly easy install Love these lights
Second bike I've had these on and won't ever have a bike without them. They are easy to install and add to the look and lighting of my bike. Highly recommended.
Bought these for my 2021 ultra limited. Great product, so easy to step it up (technically if you know your Harley it can be install without instruction.) No sync needed on my bike. They look fantastic and are very bright. Bike is a lot more visible
Work perfect make bike more visible
They stand behind their lifetime warranty also
If you take your time and read the instructions carfully; this shouldn't take longer than a couple hours to install (and thats including wire management). I've seen these on other bikes on Youtube but in person on my bike (2018 Harley Ultra Limited).......... THEY LOOK FANTASTIC!!!
They work great. Very easy to install. The lights are very bring and definitely make you more noticeable going down the road!
Easy to install, great directions.So easy I did it by myself!!! Dress up front end and makes trike more visiable.
Great product, easy step by step installation instructions with the correct connectors, so great for do it yourself install, would definitely recommend this product for your Harley
Inserts worked great - easy to follow instructions -
The printed instructions were actually better and easier to follow than ANY Youtube Videos on installation.
Recently added a pair of these suckers to my 22 CVO Road Glide Limited. As normal with Custom Dynamics, product functions and looks great, installation instructions are spot on, and customer support was stellar!
Easy install. Synced these lights along with the CD LED vent light and LED fairing trim lighting. Swapped the outdated Harley 1157 bulbs with LED turn signal lights. Man what an improvement!! Definitely can be seen now.
Customer support was also top notch. I'm a huge fan of Custom Dynamics now!
I've seen them lit; AWESOME . Install Video well done. display video make me want to order them
The installation is fairly easy. It took me longer to read the color instructions than it did to actually install the lights. They add a great touch to the lowers on the Limited bikes. Definitely recommend these lights.
bought these for my 2018 ultra limited , love them, highly recommend them
Not a wrenching person, but these lights were very simple to install. Watch the video that CD provides. Once on the bike they look great. Definitely will let oncoming vehicles know your there. And Lifetime Warranty, need i say more!!
Now that I’m retired from L.E., I truly have the time to mod up my 2019 ultra limited. I’ve been a Custom dynamics customer for years and they are my go to LED Company hands down. I just installed these inserts into my lower fairings and WOW they are nice! I’m truly impressed with their products and I’m gonna be getting more stuff for my bike. Thank you custom dynamics for all your excellent products and service!
I got these bases on Custom Dynamics excellent web site and only one review but I did see them on YouTube and figured they would be wicked nice. Well I was right! Truly plug and play and they include everything you need for the install. There’s two rows of LEDs around the entire unit and they are bright, but not over stated. Worth every penny for sure. Took me about two hours for the install on my 2015 road glide ultra and I was taking my time. If you’re considering these lights, you’ll be happy with them.
Are they ever BRIGHT!! I also have the CD windshield trim as in the picture above. They compliment each other perfectly! Took me about 2 hours to install and it is plug and play as advertised. When off, you'd never know they had LED's in them. I was hoping they'd come out with a chrome option like Kuryakyn has but I'm not in the least disappointed now that I have these. They look fantastic and did I mention how BRIGHT they are?? Plus, lifetime warranty on the LED's!! Get these lights, you won't be disappointed either.
