I just installed a pair of 7443 leds that I purchased from vleds. As soon as I installed them and started the car I had the light on the dash go on for a bad bulb. Not tragic I figured and thought I might need to add a resistor to fix the issue considering the lights were working fine. Fast forward to later in the day at first my rear lights were working fine , but after leaving a store I noticed none of my rear lights including my license plate lights are now working. So my question is..do I need to run a resistor with these bulbs? or can I not run these bulbs at all? Im gonna start tomorrow morning with checking the fuses and then if need be ill take out the led bulbs. Thanks, and Any help is appreciated

these are the bulbs also

i have those bulbs as well, but not from VLED.
no problems with them at all. no resistors needed.
did u put them in turn signal too?

 

just in the brake locations, not in the turn signals. Not sure what the deal is..

 

sounds like the fuse is blown, if it wasnt working at all i would say to turn the bulb around i know some leds, have to be plugged in a certain way

 

They were both working at first. I know if you put them in and they dont work to flip them for polarity, but that wasnt the case. I just got back from the garage and yes the fuse was blown, but there is worse news...what could cause the bulb to melt and break like this?

 

Does anyone know if our cars use standard bulbs or ck type bulbs? Difference being the grounds are either on the same side or opposite of each other...

 

Looks like a bad LED bulb. Return it to them and ask for a replacement. And just to be sure, check if the socket is wet or is there any way it's getting wet. But definitely it's a defective LED bulb.
