Does the 3157 bulb really cause hyper flashing when used as blinker light?

short answer yes ( explanation ) in most cases yes, modern cars are designed to make your blinkers flash rapidly when you have a light out, if a bulb burns out then you have lower resistance or ( load ) in the circuit. LED use less power than a standard bulb so the system hyper flashes . you can add a load resistor to stop the flash , but you also lose the ability to tell if you have a light out also load resistor get very hot and if not installed correctly can cause damage, I would recommend replacing the relay with one designed to be used with LED . then everything will work the way it was intended. or just put the LED in and deal with the fact that your blinker will blink faster, and you will have to do a walk around your vehicle to check that all your lights work, just like we did before computers came along

Will this fit my 2005 surburban

These replace standard bulbs; I.e. 3057, 3157, etc., so I am fairly certain they will fit any vehicle that utilizes those bulbs

Would this fit a 2005 Subaru Forester?

check the number on your existing bulb, these lights work great and are really bright.
