• Solution for "bulb out signal" / "OBC error message" after installing SMD LED light bulb.
  • Solution for Fast Turn Signal Blinking response after installing SMD LED light bulb.
  • Warning: Load Resistors heat up like halogen bulbs. They get really HOT when working. Mount them on metal surface, NOT plastic.
  • Installation is easy. Just connect the wires with the splice taps provided.
  • Each LED bulb installation requires one resistor connected in parellel (see picture below for instruction)

Worked like a charm for my 2015 Jeep Wrangler. I only needed to use 2 out of the 4. I figure it's good to have a couple extra in case I need them for anything. Error code went away and no more frantic schitzo blinking. Thank goodness. NOTE TO JK WRANGLER OWNERS: The 2 resistor wires attach to the black wire and the white wire with YELLOW stripe NOT the white wire with the PURPLE stripe.

I used this in a 2016 Hyundai Accent for my switchback led turn signals. I did install the lights and then tried them to see if I would be lucky enough to not need these, but I did experience hyperflash. I ended up only needing 2 of these (one on each rear light) as they are wired parallel. This was great because I don't think I would have been able to figure out where to put these on the front lights based on the way the wiring is set up. No hyperflashing, and while they do get pretty warm, I wouldn't call it "hot". I tested these for about 30 minutes nonstop on a 101 degree day and they never became too hot to handle. I would still mount these on metal only and make sure no wires or insulation/sound proofing or any other flammable material can touch them just to be on the safe side. This product is incredibly low priced, but is essential for anyone upgrading their vehicle to LED's.

Worked perfect, no longer have turn signals rapidly flashing. Mounted them with self tapping screws inside the area where the wiring runs up and out of the way.

Got these to prevent the hyperflash in my 08 ford edge. As it says in the description these things get freaking hot! They dont get nuclear or anything, about as hot as a normal bulb would get if you touched it. I was able to mount these to metal underneath my rear turn housing with enough space to keep them off the plastic so nothing gets melted. As for the front turns I have yet to actually mount them as I just have them zip tied up to keep them away from everything that could get melted. I could just leave them that way but I want a cleaner look in the future. I have had em for a couple of months now with no issues so far.

I swapped out the standard "always on" rear lights on my Volvo S60 with LED lights. The lights look great, but this car, like many nicer cars these days, have a system that tells you when a bulb goes out. The LED lights pull so little current, the CANBUS system in the Volvo can't tell they are there, and will tell you the bulb is out. To solve this, I had to get these resistors to increase the resistance in the circuit to a point that it would trick the system into believing the old style bulbs were still in place. I was told that only one resistor would do the trick but ended up discovering that wasn't true. One pulled too much current and would shut off the circuit totally. I had to link 2 in series to give me a 12 Ohm, 100 Watt load, and that worked perfectly. The resistors are mounted in aluminum finned heat sinks to dissipate the heat. There are tabs on the housing to use screws to mount to a metal surface, which will help dissipate heat even faster. It also includes the quick taps that let you make your electrical connections without having to cut any wires, which is really nice. If I had to have any complaint at all, it would be that the holes in the mounting tabs were too small for any normal size screw I had, and I had to drill them out a teeny bit. Other than that, these work great, and let me upgrade to the LED lights I had been wanting.

Works the way it’s advertised to work. For 2013 Chevy Silverado extended cab, driver side brake /running light and turn signal wires are black and yellow. Must also add resistor to to both bulbs. On passenger side your wires are black and green. Must add two resistors per bulb in order for both to stop hyper blink. On the bottom bulb add resistor to the black and yellow (driver side) and black and green ( passenger side ) to wires coming from the main feed of wires. Not from the wires leaving the bottom bulb to the top one. Same color wires in and same color out. Products is advised to be attached to hard surface due to the heat it generates and comes with mounting holes but doesn’t include self tapping screws. I guess one would have to look in junk screw box or make a trip to the store. Otherwise good product. I let mine hang thru the open ring of the frame where it doesn’t touch anything. Just hope the hanging position doesn’t wear out the connection over time.

Purchased these for taillights/turn signals on 2013 f150. These are incredibly easy to install. Took roughly 10 minutes per side. There is no wire cutting or stripping whatever involved. For anyone doing this for the first time as I was, it’s incredibly simple. You basically just clip one end into your turn signal wire, then clip the other end to the ground wire of your turn signal. I used JB Weld to attach the thing that looks like a little amplifier (the resistor) to underside of wheel well. Worked perfectly. Don’t hesitate if you’re nervous about installing these. It’s so easy, even a caveman can do it!

Just installed. Fixed my hyper flash issue. Items do get super hot like they say. Used self tapping screws to mount to the inside.

Worked exactly like it was supposed to. Easy to install in my 2008Chevy Silverado with dual blinker bulbs per side. I replaced all 4 of the flasher bulbs with LED that put it in hyper flash mode. One resister per bulb fixed it. Directions were clear. If you use the supplied quick install clamps, be sure to use pliers and completely set the cutting blade into the wires. I used the quick install to be sure it was wired correctly and test and then cut, soldered, and sealed the wires for a permanent install. If you wrap the quick install tightly with electrical tape, I think it would be fine. Do not leave the resistor touching any plastic as it will get hot.

These are needed if you install LED bulbs in place of 3057 like in my 2015 GMC Terrain Denali. Without these resisters the flash rate is hyper and the body control module actually increases the volume of the flasher sound that comes from the vehicle's speaker. It is very annoying. This package contains enough for four LED lights to be converted. You will need wire ties. The instructions say to mount the resisters to metal. I really didn't care to drill my video body to mount these. I made the wire connections, wire tied the wires together and made sure the resisters were not in contact with anything and that they were hanging free below the wire bundle. They work great and they don't seem to become overly hot. I wish there was a better option for correcting the hyper flash rate, but to date there is no better option as far as I know.
