3157 3156 T25 3057A 3357NA Led Light Bulb 5050 SMD Chipsets Replace for Turn Signal Back Up Reverse Brake Tail Stop Parking RV Lights,10Pack (white, 10pack)

I burend out about 6 of these within 10 minutes and kept blowing the fuses in the car.After dismaltiling a couple of the burned out ones, I discovered why... the pins are the wrong way around so it basically connects a +12v thorhough a resitor to 0v, so as soon as its turend on, pop goes the fues and teh resister bursn out instnalty.I re-wired a few of them to the correct pin-out..But the leds are all on the same bank, one though a resistor for side lights and the other without a resitor for the brigher brake light - but..... they both go into the same array so as soon the side-lights are on, current travels back though the pedal switch curcuit (teh wrong way) so the car thinks that the break peadal is pressed whenever the side-lights are on - which played havoc with the stop-start and push button start. Again I got around that by installing a diode onto the break light part of the curcuit but thats less than ideal so will be stopping in halfords this afternoon and going for standard bulbs I think.they look good, if you have the electronic knowelgde to dissmantle them, correct the pin-out and solder the all important diode then go for it, but for ease, I wouldnt bother.I would have sent them back for a refund but 8 of hem were omepltedly burned out and the other 4 I have pulled apart to try to find out what was going on.
