Review on ✨ TUINCYN 50W 8 ohm LED Load Resistors - Fix Headlight LED Bulb Fog Lamp Hyper Flash Turn Signal Blink Light Error Code CANBUS Resistors Decoder (1 Pair) for 3157 3047 3057 3155 3457 by William Dean

Poor fit and does not work. I bought these for my 2014 Impala LT when I installed LED brake/turn signals. They didn't perform the function they were supposed to and rendered the turn signal useless. When installed, the turn signal did not flash. The light was on but not blinking. Fit and finish are poor. If the heatsink needs to dissipate the power listed on the side of the heatsink, then that's insane. I work in IT, have built countless desktop computers, and dabbled with coolers and Peltier heatsinks of all shapes and sizes. These very small cylindrical heatsinks CANNOT put out 50W of power. They are just too small and heat up EXTREMELY quickly. Even if they worked I wouldn't put them in a car because of the heat they generate. On a hot summer day with over 100F in the trunk I can only imagine how hot it would be in them. These heatsinks didn't have the surface area for adequate heat dissipation. The fit was poor at best. They went into the socket but the 3 notches that go into the standard harness lamp body went in and it pivoted to snap into place. They were just let loose and never fixed. This caused me to lose alignment of the three slots and I couldn't get the wire harness out once it was rotated (as I couldn't line up the slots. I was eventually able to get it out, but not before my LED bulb fell out of the wire harness and into my tail light so now I have to take my entire headlight off and fish out the LED bulb that fell into that poorly designed wiring harness I don't recommend it.
