United Pacific90656 LED Sequential Light Kit for Pre 1970’s Classic Cars, Hot Rods, Early Muscle Cars, Convert LED Taillight to Sequential - ONE Unit

Works really well I hardwired it into my flatbed LED tail/turn lights. The sequence works perfect with an LED flasher relay but not well with a standard relay. Tail and turn work fine, non-sequential brake function brake lights took some effort to get a wire from the brake switch to the brake input on each module, but the brake lights will still work if you choose not to do this they will just sequence on instead of come on simultaneously.It wasn’t needed for me but I remember the old school mustang ms that had the mechanical sequencers growing up and wanted the same.

This kit looked very clean and well made but i was fooled. Once i wired it in i had multiple problems with it. First one of the grounds wasn't working properly then the actual sequential part quit working. Not satisfied at all.

I just had to write a review for this since I've seen so many bad reviews from folks who obviously don't follow instructions! This product works perfectly when installed correctly. I converted a 1995 Cadillac to led with these in 2 hours and it's working wonderfully! The instructions are excellent and the supplied connectors are high quality. The brake lights do not sequence like the turn signals (FYI, because I was curious about this too). Anyone with basic 12 volt knowledge can handle this... So why all the bad reviews?!

I'll give it at least a 4 until I get it actually installed. If I don't run into issues, then it'll be a 5 start product. Unit was as advertised and I have only tested it on the bench which it seemed to work fine but a person never knows until under actually operating conditions. I needed to order LED bulbs and LED flasher before I can make the conversion since it will require both of those items besides the controller. That may have be a good thing to mention so people will know what they are going to run into and order them somewhere at the same time. It would make installation less strung out when you get ready to do it. Also I had to run 2 more wires to the 4 trunk lid lights on my '63 Chevy since each brake light socket needs it's dedicated wire back to the controller. Not a big problem in the older cars tho since that part is easily accessable and easy to run wires along side original wiring but be aware to order some automotive wiring with 2 different colors (if you want to make it easier to identify which wire you tied to controller without tracing it back or trial & error method. (I converted the Backup light on a '63 chevy to a tail/brake light to get 3 sequencial lites) I will update later after I get all the other items in and installed but so far I think I'll like the results.

Works great! I used it on my 66 mustang, using led taillights I made from basic 4" led bars glued to a circuit board that I cut to fit inside the taillight lenses.Another review talked about the lights going crazy when the headlights are on, and I sort of experienced that too, only it's just seen that way "on camera". The flickering doesn't have anything to do with the modules though, it's a typical led phenomenon, but it isn't visible to the human eye, only cameras.

All works good, but sadly enough one of the lights burn brighter when the light is turned on and also doesn't blink when the blinker goes on. Everything works fine with the lights turned off

If you know some of electric harness well you can use this because need hand's work but work perfectly fine

I have a custom taillight set up that I bought this kit for, it has 3 independent LED lights that act as running lights when lights are on and blink when turning. This kit theoretically would be an idea choice to go with. Well I installed this kit and installation wasn't too difficult considering I understood my custom setup/wiring. The kit worked great! BUT ONLY when the lights are turned OFF. If my lights are ON then the sequence goes all crazy and out of sync and too fast when signaling to turn. So something is telling the sequencer, when "lights on" go crazy. Im thinking I might need to put in a resistor somewhere for the sequencer to think that the lights are off when they're actually on, but that will be a project for another day. I read the other comment and 2 other guys seem to be having the same issue of not functioning correctly when the lights are on. The kit does NOT work as its supposed to. I can't picture a more ideal set up than the one I have to test this kit, I tested it and it ONLY SEQUENCES CORRECTLY WHEN LIGHTS ARE OFF, DOES NOT SEQUENCE CORRECTLY WHEN LIGHT ARE ON.
