well i have a 98 blazer i ordered some led tail light bulbs to replace my old reg tail light bulbs now heres the werid part i just plugged them in and they dont work i tried both ways no luck. so i just plugged them in where my white led reverse lights are they work with no problems. so i thought maybe something was messed up so i just plugged my led reverse lights in my tail light socket and they dont work either. now does this mean i need a resistor?

 

anyone?

 

It sounds like you have a wiring issue. I'd check to see if you have power to the bulbs at all first. If not, then check the grounds and go from there.

 

well thats what i thought but i had reg brake bulbs in and they worked just fine but when i plug in my led brake bulbs in the sockets they dont light up but when i turn my turn signals they turn on with no problems but then ill turn off my blinker they shut off

 

Ok there is a possibility that you got the CK style bulb, which would cause an issue like what you describe. Here is a diagram that shows how the regular and CK style are different.


This could be the issue. Take a look and see if your bulbs say CK on them somewhere.

 

thanks but i think i found the problem there single filament bulbs after the ebay seller told me they were dual filament bulbs i cant you cant trust ebay for that reason

 

so when i buy the next set of bulbs could you tell me what to buy someone told me to get dual filament bulbs is that right

 

Yes, dual filament. 3157 NOT 3156 they are not interchangeable.
