IG Tuning Autolizer 3157 3057 3357 4157 Switchback LED Bulbs - White/Yellow Turn Signal Lights with 22 SMD for Standard Socket (Pair of 2, Not CK) - Perfect for Car, Truck, and Motorcycle Lighting Upgrades

I ordered these for my 2000 jeep wj hoping for a cheaper alternative than the Classy Auto switchbacks. Well the cheaper part was sure correct. Even the packaging screamed Chinese and horribly made. I plugged them into sockets as soon as I got them and was disappointed to find that they were wired backwards so they would stay amber and then merely flash the white LEDs with the amber still on when I turned on the turn signal. I turned them around in the socket but of course they only work one way so I was stuck with faulty bulbs. The next incidents was majorly my fault. In my infinite wisdom I decided to bend the leads of the bulb the opposite way expecting the current to flow the opposite way though the bulb's circuitry but instead I believe that it blew the turn signal relay so the signals didn't work at all. Giving up in frustration I left the turn signal repair up to professionals and is currently being fixed. It is possible that I just got a bad set but I would not take the chance again if I could redo it. Along with the money I will be spending to get Classy auto's the repair bill will put me in the hole a lot more than I "saved" by buying these bulbs. Do your car a favor and DONT.Shipped quickly and fit correctly. Since these are led's my truck unfortunately has hyperflash and i would need to buy a resitor to fix this. they fit correctly. The only problem i saw that was not my fault was that when it should have switched over to amber for the blinker the white light stayed on. This is no big deal to me but then again i could have done something (not sure what since its plug and play) wrong.I'm an international customer and I have to pay from USA to my destination country, I bought this item thinking that it comes with the load resistors for my ford fiesta HB. In the package only comes with the standard LEDs. I didn't taste the led yet however I'm very disappointed with this seller! \ Soy un comprador internacional y debo pagar adicionalmente el envío de Estados Unidos a mi país, compre estos leds pensando en que tenían los resistors y no los traen es un engaño solo para atraer cliente todavía no los he probador para saber la calidad pero estoy defraudado de este vendedor eran para mi Ford FiestaI put these bulbs in and found out not all the white LEDs work.I sent an e-mail telling them I needed a new bulb along with a picture.Im waiting for there reply.if they replace the bad bulb I will give them a better review !Got an e-mail and there sending me a new tested 3157 led bulb today!They work and are brite. But they do not work as they suppose to on a 2005 Cadillac SRX as DRLs.The bulbs are ok in a clear housing. The white lights dont turn off while yellow ones blink and yellow lights are not bright. I used them as reverse lights disabling the yellow one also I notice the why the white and yellow negative leads are bonded.No wiring instructionsFast shipping and accurate description. I would have gave 5 stars but one row of leds already went out after a week. It's probably just a defective bulb. I'll contact the company and find out about a replacement.
