Led tail light bulbs #3157

dgs003 · Jul 19, 2015

Bought 3157 led bulbs to install in the tail lights
Installed as brake, tail, and reverse lights, and blew the same fuse twice for driver side tail light
I thought it was just plug and play with theses bulbs, do I need to add a resistor somewhere or is there another issue that would cause that fuse to blow
Thanks

I had no probs on my old 2010..Just showed on the dash that i had lights out and signals flashed faster was all..

You'll definitely have to add a resistor or two. The CANBUS thinks there's a short circuit, because of the low power draw on those LEDs, so you'll have to add a resistor to make it think the bulb is using the right amount of power.

I'm not an electrical expert, so I couldn't say exactly how big a resistor you'll need to use, but I imagine someone else will be able to chime in with a formula or something.

I was going to do this also and purchased leds and they also blew a fuse, I read somewhere that the bulbs are actually 3157 srck type. hope this helps.http://www.ramforum.com/f54/important_led_replacement_bulb_info_02-06_rams-3233/
