So I just bought some LED front turn signal lights (1157A) for my 2000 ES300. I put them in and tested them, and the car acts as if the bulbs are dead. It blinks really fast indicating that the bulb is "out" when it's actually working. Also, on the box for the LED lights it says that these LED's are "CanBus", which I think means that they should trick the car into thinking that it draws the same amount of power as a regular bulb. I've tried searching the forum for this issue, but i haven't had any luck. Is there any way that I could make this work? I'd rather not return them.

 

You have to add resistors. LED bulb's ohm is too low and will make the light blink fast. Canbus error-free LED won't solve this issue. Just add some resistors and the problem solved.

resistors only.

resistors kit:

(It said LED Decoder which is BS. It's just resistors surrounded by black plastic.)
Just samples, you can find any other products.

Another way is to switch the flash relay to LED flash relay. (I believe this is the best way)

But you have to find the location of the relay first, and it has to be easy to reach.

Hope this will help.

 

This helps a lot! However, it doesn't really seem worth it to me to pay so much money for just some LED's. But I will try out one of these resistor kit thingys and see how it goes. Thanks again for the help!
