Finally no parking light out message!!

So, I didn't get these to help stop hyperflash, I needed them due to getting the parking light out message on my 2019 RAM Classic 1500 after installing new LED switchback headlights. NONE of the alphaOBD hacks worked but these did. I'm not familiar with resistors and set up so the only problem I had was they lacked any directions or troubleshooting (or at least in my shipment), had to google for best troubleshooting method. Someone online had a good note on how to test if they are set up correctly and how only one side should get hot and needing to rotate either the bulb or the connection. After finding the help document and some flipping of stuff, they worked great. Would recomment 100% over any splice type setups for sure!

Awesome plug n play

Product is as described and easy plug n play setup

Thanks again

The hyper flash was driving me crazy. Once I purchased these I really didn't think it was going to work that good, but once I put then on my Ram 1500 I was excited to see them work properly.

product worked like it should have stopped the hyper flashes thank you thank

No more hyperflash

Holy smokes that hyperflash is annoying! The connectors plugged right in, I just had to slightly shave the plastic on the base of my led bulbs to fit in the socket. No biggie. 2007 Dodge 2500.... fixed 😉!

Load Resistors work amazingly

I’m really impressed!! These load resistors really help with the hyperflash

Worked Great Besides Design

Resistors work as they should, my only complaint was how the wires were ran together. Made it difficult to mount the resisters since there wasn’t very much play

Quick and easy

The 3157 LED wiring upgrade has given me brighter tail lights with an easy install. No hyper flash any more.

Fantastic, Easy to Install

I was a little concerned after installation because my car was giving me an engine error that I couldn't put my finger on. But after starting the engine and letting it run for a little bit, brake tests and indicators worked just fine. No error codes, no hassle. And this fixed my hyperflash problem. These were also a much better solution than wiring the system manually. Thanks Underground.

Very good quality Vs Amazon shit

You can find these on Amazon for much less, but given the heat these generate I didn’t want to put that garbage on my truck. These are high quality, I’ve had them on for a month with no issues.

Great Product

Well built and easy to install. Customer support was great working through some issues with the USPS being so slow.

As described

Quick shipping and great customer support. Helped me figure out how to install these correctly and very responsive.

Perfect

This was exactly what I needed. Works flawlessly!

3157 plug and play

They are working great

very nice product. I had a hyper flash & my turn signal indicator light would light up when headlights we turned on. I installed these & no more problems. I highly recommend this product !

So far so good

They’re working good so far. No known issues. Does not hyper flash. I added some aluminum tape to the area I placed them as well as covering any adjacent wires for added heat protection.

The lights

The lights are great! Works perfectly. I would definitely recommend them.

Great Product

Very nice plug & play product. Works perfectly, and was easy to install.
