I was looking into possibly getting some 3157 LED Switchback bulbs to go in my new clear corner lights and have seen a few posts where people mention sometimes needing to get load resistors for these bulbs to prevent hyperflashing. Can anyone chime in with their experience with these bulbs and whether or not we need the load resistors, or if the need for them is dependent on individual car, year ...etc. In some posts, throughout multiple forums, people seem to say they didn't need them and others say they did for different types of cars. I was looking for a definitive answer for our cars if there is one. Thanks in advance

 

Just installed some. Definitely need the resistors or it will go haywire. I got mine from hidguy

 

yes, you need them no matter what type of car. V-leds.com is where i got mine. you need 6 ohm for the front if you are only running front led's OR you will need 3 ohm if you are running front and rear led's

 

this is such a common problem, why dont they make led replacement bulbs with resistors built-in?

 

Resistors generate a ton of heat. LED bulbs generate a fair amount alone. I imagine it would kill the bulbs.


+1 for resistors.

 

led's barely give off any hear, if any....

 

Ever seen a high powered LED bulb?
