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.

Simple yet perfect

Product arrived quickly to my home. At first noticed packaging was very simple and didnt give much insight on sizing or additional information. Opened and well packed along with pamphlet of instructions for care and Install. Quick and easy to replace with former bulbs and work great. Great look and absolutely brighter than standard. Worth the money.

Bright White, happy so far!

LED Lights look so much better than the original halogen. These LEDs are bright! I did notice the fit wasn’t perfect but it was close enough where I could wedge it in the socket and they work!

Flash very fast

These are quite bright, and seem to be of fairly good quality, but when installed in my truck they caused the turn signals to flash extremely fast, and this messed with my tailgate light bar, so I ended up not using them and went with my stock lamps.

I use them as reverse lights

I put these in as reverse lights in an 07 Silverado.I went from not being able to see the end of my own driveway, about 15 feet, to literally lighting up my neighbors garage door about 175 feet away at the darkest point in the night. Mind you I see this through 5% limo tint on the rear window.Are they bright? Yeah.Durable? Don't know yet.Do they strobe out? Mine don't.Would I buy more? Absolutely.
