The genesis 4 lights are so much brighter than stock lights. They were easy to install and are more visible to traffic.
Very bright running lights.
Absolutely love the look, the white light while riding makes me feel that I am seen by oncoming traffic.
Truly plug and play! I found a wiring issue that was already there and once I traced all that down these worked like a charm! Love them!
I buy these light because they are the ones on the market warranty is a life time replacement with out any static
The Genesis 4 turn signal inserts are a huge improvement over the stock lights and are much brighter. They go from solid white to flashing amber when the turn indicator is activated. Highly recommend.
Super easy install and shipping is super fast. HIGHLY RECOMEND
Really bright. Easy install. Well made. Like the non halo look.
Before these, my turn signals were just turn signals. I stayed on Amber went not in use. Now they provide additional light almost like running fog lights. Highly recommend.
Very pleased with these lights, coming from a similar halo style which might have been from here not sure… but one failed after 4 yrs so replaced with these gen 4 solid versions. I Love the brightness and pattern of the light, reminds me of Iron Man. Switched from smoked to clear lenses also to be brighter up front.
I received the Genesis 4 turn signal inserts from Custom Dynamics promptly was able to install both of them in about 15 minutes. They are a huge improvement over the stock lights, being much brighter. They go from solid white to flashing orange when the turn indicator is activated. I am very happy with this product.
I tried some other brand turn signal inserts before these and they worked just fine, but they are not as good. The other two sets were not as bright and flashed between amber and white when your turn signals were on. These work how they should and the white light goes out then it flashes amber with the turn signal on. When the turn signal goes off they go back to steady white. The only downside to these over one of the others I tried was the wiring was in a loom with heat shrink around the connections unlike these. This isn't a big deal since they are inside the turn signal but its a nice little touch I wish these had. Other than that these are much better hands down.
I bought a set of the Dynamic Rings (front) Turn Signals in 2015, last week I noticed i had 3 LED's that were burnt out. March 13, 2023 I contacted them by phone, texted a couple photos of the lights and the same day I had a invoice for new upgraded set of Gen 4 turn signals in my email. Today March 15th I received them, THREE days (3), from the time I called, a new even better product in my hands from NC to WA State. They stand behind their product and other companies should mirror their Customer Service.
2013 Harley Road Glide Custom. Lights delivered on time. Installation instructions on point. Mannnnnn! What a difference! Love it! I will be ordering more Products.
I just installed these on my 22 Tri Glide., These are VERY bright lights and very easy to install. My amperage dropped from 14.5 ( factory ) to little over 12 amps, for someone that deals with gaming computers and networking that's a very big deal.
Awesome lights and bright
Purchased The Genesis 4 turn signal inserts. The shipping was quick. I had a small issue installing and customer support was spot on with a solution in a very timely manner. I could not be happier with my purchase and the turn signals. They are bright and you will be seen. Great company, products and customer support. I have already ordered and installed a rear tail light and will be ordering saddle bag lights in the near future.
Easy install and very bright. Exactly what I was looking for. Not a fan of the halo lights. Highly recommend
I’m a big advocate of having a bright bike. In my world there can never be enough lights on a bike.
I welcome these as a great addition up front!
Awesome Product easy plug and play. Didnt want halo so this is the one.
I installed these a year ago.. I run the smoke lens up front.. They are very bright, like adding another pair of passing lamps! But when the turn switch is activated, that side flashes a very bright yellow while the other side remains white. These are attention getters! They are NOTICED! Super simple install, that is a huge improvement over the stock turn indicators.
