don't do load resistors. just get a flasher relay from ijdmtoy to replace the one that came with the vehicle. so relays even have speed control so you can control the speed of your flashers.

btw, i have a pair of 3157 bulbs for sale for the front signals. these are the CK version which our vans need. i used them for a couple months then swapped to switchbacks. they are in perfect working condition and very bright. i originally paid $80 for the pair but will let them go for $30 shipped. PM if interested.

 

Ordered and pmd. Thanks Rob

 

How many relays do we need for front and rear turns?

 

1 relay will take care of all your flashers. you can convert front or rear, or both to led and will not hyper flash.

 

It shows the relay as applicable for 2012-2014. Does anybody know if it also fits 2011?

 

you can also try these... https://www.superbrightleds.com/mor...m_campaign=GoogleBaseChild&gclid=CNbZkbm2hsUCFQGTfgodVzYA1g#/tab/Specifications

the compatible part #'s are one the specs page to see if yours will work.

 

Thanks Rob. Guess the only way to check is actually pull the old one out to get part number? You aware anyone running it with 2011 SE?

 

i'm running them on my 11 SE and i know a few other 11's with them. the only one that had problems was actually a 13 model.

 

That is exactly what I wanted to hear. Not sure why most of the websites list it by year and don't include 2011 model. Will order one without pulling out old one to check. Too much of a hassle...
