one turn signal is blinking fast? Options

[DSToyo]

when i bought my car, the passanger side blinkers (front & back) blink twice as fast and half as bright, while the drivers side blinks and is bright normal
-i have replaced the bulbs in the front and it didn't do anything at all
-the wires don't look tampered or destroyed at all
i just want to get them to blink the same again and don't really know how to, ive read some other posts on topics like this but dont really get it.

i guess im going to change the bulb in the back to see if that helps
thanks for any help/suggestions

Either that or one of the bulbs that are pluged into a blinker outlet are LED's. And the other isn't because LED's in your blinkers make your blinkers blink faster
