They're all 12V... the easiest way to install the LEDs in your car safely is just by hooking a 1K ohm resistor up to either lead of the LED then just hooking the + and - up and you're good to go. The resistor limits the current (amperage) that goes to the LED and keeps it from "poping"...

I actually poped a few last night on accident while building my new tail lights.... damn short in the circuitboard... I wasn't happy I blew 6 $1.50 LEDs.... But I got all of them built... now this weekend's project is to do the final assembly and get my car back together...

I just put in 2 today.... they look great.. i swapped out those red lights on the door handles and put in an led.. i used 1 led and a 470 ohm resistor... had em in for a few hours and everything looks to be good
... 470 ohm is the correct resistor right? i used ohm's law to figure it out

So this means if you put the LED bulbs in your blinkers, they are gonna pop?

I bought some for my brakelights (red 3157), and after I put one in, my fuse blew. Any correlation, or just a coincidence? They are made by APC, and said they are a replacement for 3157 bulbs.

No, by pop they mean that the actual led bulb will bust not your fuse.

If you had a fuse pop after putting them in that means they are drawing too much of a load for the fuse you have. Just go and buy some lower watt bulbs to fix this, but I would first try a new fuse and see if it does it again if so then go buy soem lower watt bubls.
