United Pacific 90652 LED Flasher w/Polarity Reversing Adapter, Easy Plug-In Design, 12V DC System, 20amp - ONE Unit

I was having issues after installing led lights for parking lights and rear leds on my 62 impala,plus I had a new steering coulmn with adapters and new wiring and new mechanical flashers,first I thought it was a ground issue cause the front leds would flicker, turn signals were solid instead of flashing and online forums said try the led flashers with ground, so I bought 2,1 for my car fuse box and 1 for the adapter for 4 way flasher and it was it beautiful, every issue disappeared and EVERYTHING WORKS PERFECTLY,I almost put resistors on each light as some say it works also but others said if I put led flashers I wouldn't need the resistors and led flashers are much simpler to do first then adding resistors and now there's no need for resistors as these led flashers cured all problems

Installed LED brake/ turn signal lights on my 1970 Chevy C20. When using the turn signals the light would come on solid and not blink. This 100% fixes that. Would be 5-star except for. 1) The connection on the adapter was smashed and I had to open it up with a screwdriver, not a big deal but it felt like it was going to break at times. 2) The grounding cable is on the short side, it worked but to make it a clean install I'm going to have to lengthen the wire. Overall super happy with the product.

This worked great for my 1969 Mustang (Convertible)... I installed the U.P. sequential LED tail lights and with incandescent turning bulbs in the front, the old flashers worked fine - all based on current draw. However when one of the front bulbs burnt out, that side's rear LED tail light didn't work. I was able to use 90652 to replace both my turning and hazard flasher cans. The turning flasher did NOT require the reverse polarity adapter that comes with the 90652 kit. The hazard flasher however, DID require the use of the reverse polarity adapter.I spun my wheels on which of these United Pacific flasher units to get, but here's the break down - for the two prong flashers, they're all the 90650 flasher. The 90649 comes with the flasher, the reverse polarity adapter, AND extension wires which could be handy to have. The 90650 is just the flasher. The 90652 is the flasher AND reverse polarity adapter.

Works perfect for led replacement bulbs! Must have

I installed LED bulbs all around my 1969 Ford Fairlane for all the added benefits of LED. Blinkers wouldn't work so I had to buy a set of resistors but you have to have one resistor for each bulb that flashes. I should have researched and found this relay.I installed it and had to use the polarity reversing plate but no big deal. Works great and has a nice sound, the flash is consistent. The only problem I had is that my old relay has a nipple on the top and that holds the relay into position under the dash. This does not have that so I drilled a small hole in the top and used a screw and washer to hold it into place.If you have to drill a hole in the top please be careful on how far the bit or screw goes into the relay because it can hit a capacitor inside.

We bought two of these after converting my sons 1996 F-250 to all LED lights. It works perfectly. You need two of them for this truck. One for the turn signals (use the polarity reversing cap), and one for the four way/hazard flashers (without the polarity reversing cap).

Installed all LEDs in my 88 ram, and plan to in my 66 f100. I installed the flasher unit today in the hazard and another in the turn signal location. Everything works flawless. Looks like a modern vehicle, and the clicks are distinct.No hyper flash, no clicks after disengagement of the hazards or signals, easy to install.

Worked great on my 1983 CJ7 Jeep. I went with all LED's and needed these for the hazards and blinker lights on my fuse box. Very easy to replace the old ones with these.

This was installed after I converted my brake and turn signal lights over to LED. It was needed because of the reduced resistance and the old flasher unit would not flash the lights.

Excellent quality. Cheapest I have seen for same brand.

Quality products from this manufacturer, highly recommend to anyone.
